1. INTRODUCTION

Features of the e-drofan family:

• Remote terminal with elegant appearance and diversifi ed access to the various functions (set point modifi cation on front buttons, change operating mode etc. on side buttons). NTC probe on board;

• Built-in LCD terminal with on-board probe;

• Remote control with LCD on board;

• Dipswitch for simple confi guration by the installer;

• Control board with high number of I/O (5 digital inputs, 3 probes, 5 relay outputs);

• Possibility to create local broadcast networks (up to 5 slaves, max 30 m);

• Possibility to create extended networks (up to 1 km) using optional CANbus serial card. Flexible space management;

• Implementation of hydronic systems with synergy between the chiller controller-e-drofan using optional

CANbus serial card;

• Customisable supervisory system thanks to the numerous protocols supported (Modbus, CANbus, PlantVisor);

• Parameter programming key;

• Options for the control of modulating valves (3 point, 0/10 Vdc input).

drofan is an electronic controller for fan coil units that optimises the performance of the cooling/heating system in order to achieve maximum comfort and considerable energy savings. It is easy to install and use, and allows the rapid re-confi guration of the unit in the event where there are changes to the spaces being air-conditioned.

The network connection simplifi es the operations if the installation has a high number of fan coils, as well as offering advanced supervision and automation functions (time bands, energy savings etc.), thanks to the integration with the chiller (pCO)/heat pump or boiler controller.

The information provided below has been divided based on the area of interest: user, installation, and advanced settings (typically reserved for the manufacturer of the air-conditioning system). e-drofan - +030221266 - rel. 3.6 del 26.04.2010

The following section shows all the default functions available on the e-drofan; the device can in any case be reconfi gured by the manufacturer of the cooling/heating system or by the installer (according to the features of the installation), and therefore some functions may not be available; in particular, if a series of e-drofan are connected in a hydronic network (highlighted by the special symbol on the display), some settings are fi xed by the manager of the installation and cannot be modifi ed.

Important: in the event of power failures, the clock setting will be lost and needs to be reset (the time fl ashes). Modify the time using the UP and DOWN buttons, and confi rm by pressing the SET button, after which the terminal can be used. e-drofan - +030221266 - rel. 3.6 del 26.04.2010

2.1.1 Manual operation: cooling

Once the device has been switched on using the ON/OFF button, proceed by:

• Pressing the MODE button repeatedly until the cooling symbol comes on.

• Setting the set point (desired temperature) using the UP and DOWN buttons.

• Pressing the FAN button repeatedly to select the desired fan speed; if AUTO mode is selected the speed is decided by the electronic controller based on the deviation from the set point (the greater the deviation, the higher the speed).

The fan only starts if the temperature of the coil is low enough, so as to avoid undesired fl ows of hot air.

If this condition is not satisfi ed the cooling symbol fl ashes.

2.1.2 Manual operation: heating

Once the device has been switched on using the ON/OFF button, proceed by:

• Pressing the MODE button repeatedly until the heating symbol only or heating with heater symbol (if installed) comes on. In the latter case the electric heater is also used as a source of heat.

• Setting the set point (desired temperature) using the UP and DOWN buttons.

The fan only starts if the temperature of the coil is high enough, so as to avoid undesired fl ows of cold air.

If this condition is not satisfi ed the heating symbol fl ashes.

If the electric heater is installed (highlighted by the special symbol on the display) the fan continues operating for 20 s even after it has been stopped. This time must also elapse even if the unit is switched off using the ON/OFF button.

2.1.3 Manual operation: dehumidifi cation (DRY

Once the device has been switched on using the ON/OFF button, proceed by:

• Pressing the MODE button repeatedly until the dehumidifi cation symbol comes on;

• Setting the set point (desired temperature) using the UP and DOWN buttons;

• Pressing the FAN button repeatedly to select the desired fan speed; if AUTO mode is selected the fan

operates at minimum speed.

The fan only starts if the temperature of the coil is low enough, so as to avoid unwanted fl ows of hot and humid air. If this condition is not satisfi ed, the dehumidifi cation symbol fl ashes.

The e-drofan starts in cooling mode so as to bring the room temperature near to the set point (set point +

3 °C) using the set speed, then performs fan on/off cycles at minimum speed to remove the humidity.

2.1.4 Manual operation: fan

Once the device has been switched on using the ON/OFF button, proceed by:

• Pressing the MODE button repeatedly so that only the fan symbol (at the bottom of the display) and the corresponding bar are on.

• Pressing the FAN button repeatedly to select the desired fan speed; if AUTO mode is selected the speed is set to medium.

The fan only starts if the ambient temperature is within the range of temperature 15 to 35 °C, so as to avoid undesired fl ows of hot or cold air.

2.1.5 Automatic operation

Once the device has been switched on using the ON/OFF button, proceed by:

• Pressing the MODE button repeatedly until the automatic symbol comes on;

• Setting the set point (desired temperature) using the UP and DOWN buttons;

The mode (heating or cooling) is decided by the electronic controller based on the deviation from the set point; if the room temperature is higher than the set point the control performs the cooling function while if it is lower it performs the heating function.

The fan only starts if the temperature of the coil is suitable to perform the heating or cooling functions.

2.1.6 Comfort control

In some installations only automatic mode is available, and the set point is decided by the manager of the installation; in these cases the user can increase or decrease the set point up to 2 °C to compensate for the different perception of the room temperature.

The value is modifi ed by pressing the UP and DOWN buttons and is displayed for 5 seconds, after which the display returns to the previous situation.

2.1.7 Setting the clock and On/Off timer

e-drofan offers the possibility to perform programmed starts and stops if the room only needs to be air-conditioned at certain times of the day. To be able to use these functions, the internal clock needs to be set with the correct time, as shown below:

• Hold the timer button for 5 seconds (Fig. 2.11);

• Set the time using the UP and DOWN buttons (the time fl ashes, Fig. 2.12);

• Confi rm by pressing the SET button (the time is on steady, see Fig. 2.13).

Fig. 2.i

Fig. 2.h.b

Fig. 2.h.c

Important:

In the event of power failures, the clock setting will be lost and needs to be reset, as does the On/Off timer.

In this case, the time fl ashes and starts from 12:00. The clock can be hidden by suitably confi guring the parameters (see section “constructor”).

The timer ON (start) is set by:

• Pressing the TIMER button once;

• Setting the required start time with the UP and DOWN buttons (the time fl ashes);

• Confi rming the time with the SET button (the symbol is on steady and the current time is displayed).

The timer OFF (stop) is set as for the timer ON, with the difference that the TIMER button must be pressed twice.

The timer ON/OFF functions remain active even after the corresponding ON/OFF event has occurred; to disable these functions proceed as follows:

• Press the timer button: once to disable the timer ON or twice to disable the timer OFF (the time fl ashes);

• Press the clear button (the special symbol disappears).

2.1.8 Sleep operation

The SLEEP function is especially useful during the night-time, when the decrease in body temperature

(due to sleep) changes the perception of the room temperature.

In cooling mode the set point is increased by P18 for the number of hours set, after which the e-drofan returns to the previous situation (the SLEEP function is cancelled).

In heating mode the set point is decreased by the value of P19.

To set the sleep function, proceed as follows:

• Switch the device on using the ON/OFF button and select the operating mode;

• Press the SLEEP button repeatedly until setting the required number of hours for the function.

To cancel this function, proceed by pressing the SLEEP button again, after having waited 3 s since the button was last pressed, or pressing the button more than once until exceeding the maximum number of hours, that is 9.

The SLEEP function can be combined with the timer OFF (see Fig. 2.i).

e-drofan - +030221266 - rel. 3.6 del 26.04.2010

2.1.9 Remote off

When the remote off symbol is present the operating mode is set to automatic (with heater, if installed) and the user can: switch the unit on/off, modify the set point and set the fan speed; the other functions are not available.

2.1.10 Alarms

The “acqua” terminal displays any alarms relating to the malfunctions of the device, shown in the summary table below. In the event of alarms, contact the relevant personnel (manager of the installation or installer/maintenance engineer) and make note of the signal to assist the response.

2.2.2 Manual operation: Heating with or without heater

Once the device has been switched on using the ON/OFF button, proceed as follows:

• press the MODE button repeatedly until the heating symbol comes on. If the heater is installed it is always used;

• set the set point (required temperature) using the UP and DOWN buttons;

The fan only starts if the coil temperature is high enough, so as to avoid unwanted fl ows of cold air. If this condition is not satisfi ed, the heating symbol fl ashes.

If the electric heater is installed, the fan continues operating for 20 seconds after deactivation. This is also valid when the unit is switched off from the ON/OFF button.

2.2.3 Manual operation: Dry (dehumidifi cation)

Once the device has been switched on using the ON/OFF button, proceed as follows:

• press the MODE button repeatedly until the dehumidifi cation symbol comes on.

• setting the set point (desired temperature) using the buttons UP and DOWN.

• press the FAN button repeatedly to select the desired fan speed; if AUTO mode is selected, the fan operates at minimum speed.

The fan only starts if the coil temperature is low enough, so as to avoid unwanted fl ows of hot air. If this condition is not satisfi ed, the cooling symbol fl ashes.

The e-drofan starts in cooling mode so as to bring the room temperature to near the set point (set point

+ 3°C) using the set fan speed, and then performs fan on/off cycles at minimum speed to remove the humidity.

2.2.4 Manual operation: Fan

Once the device has been switched on using the ON/OFF button, proceed as follows:

• press the MODE button repeatedly until only the fan symbol (at the bottom of the display) and the corresponding bar are on;

• press the FAN button repeatedly to select the desired fan speed; if AUTO mode is selected, the fan speed is fi xed at medium.

The fan only starts if the room temperature is in the range of temperatures from 15 to 35°C , so as to avoid unwanted fl ows of hot or cold air.

2.2.5 Automatic operation

Once the device has been switched on using the ON/OFF button, proceed as follows:

• press the MODE button repeatedly until the automatic symbol comes on;

• set the set point (required temperature) using the UP and DOWN buttons;

The mode (heating or cooling) is decided by the electronic controller based on the deviation from the set point; if the room temperature is above the set point, the controller switches to cooling mode, while if it is below the set point, heating mode is activated.

The fan only starts if the coil temperature is suffi cient to perform the heating or cooling functions.

2.2.6 Comfort control

In some installations, the set point is decided by the manager of the installation; in these cases, the user may increase or decrease the set point by 3°C to compensate for the different perception of the room temperature.

The set point is changed by pressing the UP and DOWN buttons, and is displayed for 5 seconds, after which the previous display resumes.

Automatic mode with comfort active (Fig. 2.m.f).

Comfort setting in automatic (Fig. 2.m.g).

2.2.7 Sleep function

The sleep function is especially useful at night, when the decrease in body temperature (due to sleep) changes people’s perception of the room temperature.

In cooling mode, the set point is increased by P18 for the number of hours specifi ed on the panel, after which the e-drofan returns to the previous operation (the sleep function is cancelled).

SLEEP display active (Fig. 2.m.h).

In heating mode, the set point is decreased by the value of P19.

To set the sleep function, proceed as follows:

• switch on the device using the ON/OFF button and select the operating mode;

• press the SLEEP button repeatedly until setting the desired duration of the function in hours (exceeding the maximum number of 9 hours disables the function).

To see the remaining time for the sleep function, press the sleep button once (after having waited 3 seconds since last pressed), and press it again to leave the function.

The sleep function is always cancelled after a power failure.

2.2.8 Remote lock

When the remote lock symbol is present, the operating mode is fi xed on automatic (with heater, if installed) and the user can: switch the unit on/off, change the set point and set the fan speed; the other functions are not available.

• Pressing the MODE button repeatedly until the heating symbol only or heating with heater symbol (if installed) comes on. In the latter case the electric heater is also used as a source of heat;

• Setting the set point (desired temperature) using the UP set point and DOWN set point buttons;

The fan only starts if the temperature of the coil is high enough, so as to avoid undesired fl ows of cold air.

If the electric heater is installed the fan continues operating for 20 s even after it has been stopped. This time must also elapse even if the unit is switched off using the ON/OFF button.

Heating with heater (Fig. 2.p.b)

Heating without heater (Fig. 2.p.c)

2.3.3 Manual operation: dehumidifi cation (DRY)

Once the device has been switched on using the ON/OFF button, proceed by:

• Pressing the MODE button repeatedly until the dehumidifi cation symbol comes on;

• Setting the set point (desired temperature) using the UP set point and DOWN set point buttons;

• Pressing the FAN button repeatedly to select the desired fan speed; if AUTO mode is selected the fan operates at minimum speed.

The fan only starts if the temperature of the coil is low enough, so as to avoid unwanted fl ows of hot and humid air.

The e-drofan starts in cooling mode so as to bring the room temperature near to the set point (set point +

3 °C) using the set speed, then performs fan on/off cycles at minimum speed to remove the humidity.

2.3.4 Manual operation: fan

Once the device has been switched on using the ON/OFF button, proceed by:

• Pressing the MODE button repeatedly so that only the fan symbol (at the bottom of the display) and the corresponding bar are on;

• Pressing the FAN button repeatedly to select the desired fan speed; if AUTO mode is selected the speed is set to medium.

The fan only starts if the ambient temperature is within the range of temperature 15 to 35 °C, so as to avoid undesired fl ows of hot or cold air.

2.3.5 Automatic operation

Once the device has been switched on using the ON/OFF button, proceed by:

• Pressing the MODE button repeatedly until the automatic symbol comes on;

• Setting the offset (from -2 to +2 °C) from the set point in automatic mode (25 °C, the fi nal set point thus ranges from 23 to 27 °C), using the UP set point and DOWN set point button

The fan only starts if the temperature of the coil is suitable to perform the heating or cooling functions.

If the network connection is present, the set point is decided by the manager of the installation; in these cases, the user can only increase or decrease the set point by 2°C to compensate for the different perception of the room temperature.

• Set the time using the TIMER UP and DOWN buttons (Fig. 2.p.h);

• Confi rm by pressing the SET button (see Fig. 2.p.i).

Important:

In the event of power failures, the clock setting will be lost and needs to be reset (the time is displayed correctly on the remote control), as does the ON/OFF timer. To reset the clock, clock send any command to the e-drofan.

Fig. 2.p.l

Fig. 2.p.n

Fig. 2.p.g

Fig. 2.p.m

Fig. 2.p.h

Fig. 2.p.i

The timer ON (start, Fig. 2.p.l) is set by:

• Pressing the TIMER ON button once;

• Setting the required start time with the TIMER UP and DOWN buttons;

• Confi rming the time with the SET button (the symbol is on steady and the current time is displayed).

The timer OFF (stop, Fig. 2.p.m) is set as for the timer ON, with the difference that the TIMER OFF button must be pressed.

The timer ON/OFF functions remain active even after the corresponding ON/OFF event has occurred; to disable these functions proceed as follows:

• Press the TIMER ON/OFF button;

• Press the clear button (the special symbol disappears).

2.3.7 Sleep operation

The SLEEP function is especially useful during the night-time, when the decrease in body temperature

(due to sleep) changes the perception of the room temperature.

In cooling mode the set point is increased by P18 for the number of hours set, after which the e-drofan returns to the previous situation (the SLEEP function is cancelled).

In heating mode the set point is decreased by the value of P19.

To set the sleep function, proceed as follows:

• Switch the device on using the ON/OFF button and select the operating mode;

• Press the SLEEP button repeatedly until setting the required number of hours for the function.

The SLEEP function can be combined with the timer OFF (see Fig. 2.p.n).

When the SLEEP function is active the brightness of the LED on the IR receiver board decreases.

2.3.8 Keypad lock

When the keypad lock symbol is present, only the ON/OFF function is enabled. To activate the lock, press the CLEAR button for 5 seconds, and to deactivate the function repeat the operation.

2.4 Additional functions

Air-conditioned rooms are normally subject to the phenomenon of air stratifi cation, due to the fact that the hot air moves upwards while the cold air moves downwards. To overcome this, the e-drofan runs fan on/off cycles (at minimum speed) once the temperature set point has been reached, so as to create a uniform room temperature. To ensure the correct measurement of the room temperature, the e-drofan runs a fan cycle for 30 s on power-up and whenever the mode is changed.

In automatic mode, this cycle is used to decide whether to heat or cool the environment.

If control is performed using the probe on the acqua terminal, these fan cycles are not performed.

2.5 Troubleshooting

Problem

The fan on one slave doesn’t start

The fan does not work at the set speed

The e-drofan does not switch on/off at the set time

Solution

The temperature of the coil may not be hot or cold enough, or alternatively the room temperature has already reached the set point. Wait; if the fan remains off for an extended period contact the relevant personnel.

The temperature of the coil may not be hot or cold enough, the initial fan cycle at minimum speed may be in progress, or alternatively the fan is operating so as to ensure a uniform temperature in the environment.

A power failure may have occurred.

Acqua terminal: reset the time and the TIMER ON/OFF or SLEEP function.

Remote control: press any button to reset the clock and the ON/OFF timer, SLEEP functions.

If a local network (tLAN) is created and the remote control is used (the LCD terminal must not be fi tted), on the master (between terminals GN and V+) insert the 1.3 kOhm resistor, supplied. This operation assigns the corresponding e-drofan the role of master, and the receivers on the other e-drofans connected to the master tLAN will automatically be deactivated.

Warnings: All installation and maintenance operations must be carried out with the unit off;

Serial connections: do not use star connections (use chain connections, see the paragraph “tLAN and

Broadcast networks”). Connect the shield to terminal GN;

Avoid short-circuits between pins GN and V+ (power supply to the LCD terminal);

Adopt precautions against electrostatic discharges when handling the boards;

Do not earth terminal GN, as this may damage the instruments in the event of network connection.

3.3.3 Basic settings and functions available (dip-switch)

The dipswitches on the fan coil board can be used to select the predefi ned settings relating to the type of fan coil and installation. Each input/output can nonetheless be reconfi gured so as to guarantee greater fl exibility; in this case (as for the advanced functions) the terminal needs to be used to modify the parameters. To perform this operation, enter the special password (refer to section “constructor”).

Set the dipswitches as follows:

1 ON=

2 ON=

3 ON=

4 ON=

5 ON=

6 ON=

Enable heat/cool functions (probe B2 on coil). Probe B3 enabled only when DIP1= ON and

DIP4= ON;

Enable remote cooling/heating digital input (DI2);

Enable remote off (some functions are disabled: timer ON, timer OFF, sleep. The operating mode is forced to “auto”);

For 4-pipe fan coils (OFF=2 pipe);

Electric heater present (when DIP 4=ON the setting is ignored and the heater is not enabled);

Control performed using the probe inside the terminal, if OFF probe B1 is used.

3.3.4 Programming key (copy the confi guration)

Once having set the parameters, the confi guration can be quickly copied to other e-drofan controllers using the programming key. Proceed as follows:

1. Switch off the previously programmed e-drofan (source);

2. Set the dipswitches inside the programming key (underneath the battery cover) to reading mode (dip

1= OFF, dip2= OFF );

3. Insert the key in the special 4 pin connector on the adapter, and connect the 8-wire cable supplied (see

Fig. 3.18);

4. Disconnect the 8-wire cable on the IR receiver board (if present) from the e-drofan;

5. Insert the 8-wire cable from the programming key adapter to the IR connector on the e-drofan board

(source), see Fig. 3.19;

6. Press the button. The red LED and then the green LED come on in succession, if the operation has been completed with success. Other signals indicate problems (refer to the corresponding instruction sheet);

7. Remove the key and the adapter; set the dipswitch to write mode (dip 1= OFF, dip2= ON ) and repeat steps 3, 4, 5, 6 to write the data to the target e-drofan;

8. Once having completed the sequence reconnect the IR receiver board on the source and target edrofan.

Important: To avoid of excessively draining the batteries in the programming key, disconnect the normally closed digital inputs on the e-drofan. If this is not possible, use the key with the power supply. The e-drofan parameters (source) can be copied to devices with the same software version or lower.

3.3.5 LCD terminal

Avoid installing the terminal in places where the ambient temperature measurement may be altered: outside walls, near doors leading to the outside, exposed to the sun, etc. (the terminal should be fastened to the wall in a horizontal position so as to allow the recirculation of air through the slits on the rear cover fastened to the wall). The terminal is fi tted inside the plastic case and is only accessible by removing the front cover (see the following fi gure).

Avoid placing the terminal in places where the room temperature measurement may be altered: outside walls, near doors leading outside, exposed to the sun, near the fan coil etc. The terminal is located inside the plastic case and is accessible using a screwdriver.

Below is the sequence of operations for wall mounting:

• fasten the 3 gang support to the box for built-in installation using two screws;

• make the connections between the terminal and the wires in the shielded cable from the e-drofan. terminal meaning

• insert the terminal in the plastic support;

• insert the fastening “shoulders”;

• position the wallplate on the support.

The following wallplates can be used: BTicino Living International; Light; Light Tech; Matix VIMAR Idea;

Idea Rondò; Plana.

If the local network (tLAN) is used, the terminal assigns the role of master to the fan coil connected.

Warnings:

• all installation and maintenance operations must be carried out with the unit off;

• adopt precautions against electrostatic discharges when handling the board.

Fig. 3.k

Fig. 3.l

The diagram in Fig. 3.k describes the connections to be made to the e-drofan board.

3.3.7 Installing the modulating valves (3 point and 0-10V, with thermal actuator)

The e-drofan can control modulating valves using a P+I algorithm, see the “manufacturer“ section for the appropriate confi guration of the parameters.

3.3.8 Protection against electric shock and maintenance warnings

Important:

The system made up of the control board (HYFC0*****) and the other optional cards (HYVC000R0*,

HYPA******, HYIR******, HYSC00F0C*, pCO serial cards etc.) represents a control device to be incorporated in class I or II appliances.

The class of protection against electric shock depends on how the control device is integrated into the unit built by the manufacturer.

Disconnect the power supply before working on the board during assembly, maintenance, replacement and confi guration. The protection against short-circuits must be guaranteed by the manufacturer of the appliance that the control device in integrated into or by the fi nal installer.

3.3.9 Broadcast networks

In summary:

• Basic broadcast networks (max 5 slaves, max 30 m);

• Extended broadcast networks (up to 1 km, max 100 units) using the CANbus board;

• Simple reconfi guration from extended broadcast to hydronic system.

The network connection is used to simplify the operation of installations with multiple fan coils. For smaller environments, the tLAN can be used to create a small local network (basic broadcast) made up of a master and a maximum of 5 slaves (maximum total length: 30 m). In this case, the information is sent in one direction only: from the master to the slaves; all the settings on the master (the only unit fi tted with the terminal) are applied to the slaves. By setting DIPSWITCH 6 on the master to ON, all the fan coils perform the control functions using the probe on the terminal, while if set to OFF, each fan coil performs the control functions using its own internal probe B1.

tLAN networks can also be created using the remote control as the user interface; in this case, the e-drofan master must be fi tted with the IR receiver board and the resistor supplied must be connected between pins GN and V+.

Notes:

• A slave unit, disconnected from the network for at least 8 seconds, is automatically switched off;

• The panel only displays the status of the master;

• The slave alarms are managed locally and independently;

• If using the remote control, each fan coil performs the control functions using its own probe;

• The settings of the dipswitches present on the slave are ignored;

• The digital inputs on the slaves are disabled, with the exception of the ON/OFF and window alarm input;

• The parameters on a slave can be modifi ed by disconnecting the network and connecting the terminal.

Once the network is restored, the slave maintains the modifi cations (unless these concern the settings overwritten by the network);

• The following settings are sent by the master to the slaves: ON/OFF, mode (e.g. heating ..etc.), fan speed, SLEEP function, On/Off timer, set point, control probe (if DIP 6 on the master is ON).

Example of basic broadcast network

Fig. 3.m

e-drofan - +030221266 - rel. 3.6 del 26.04.2010

To cover distances greater than the 30 m (up to 1 km in total) or connect more slaves, CANbus communication is required, using the serial board code HYSC****** (on each controller).

The following fi gure shows an example of an extended/multi-zone broadcast connection.

Fig. 3.o

Fig. 3.n

The features of the CANbus connection are the following:

• Maximum number of units connected: 100;

• Maximum number of masters: 15;

• Maximum number of slaves: subtract the number of masters from 100;

• Maximum number of slaves for each master: all slaves available;

• Maximum length of the CANbus (total): 1 km with low communication speed (65 kbit); 500 m with high communication speed (125 kbit);

• Connection cable: Shielded cable, 2 wire + shield;

• Connect the two 120 ohm resistors to the ends of the CANbus (between terminals H+ and H-).

The behaviour is the same as in the case of the tLAN. The master has the control panel and sends all the slaves the status to be repeated.

Each controller must be fi tted with a serial board and each slave must have the same address as the master it serves.

The serial address is set on the group of 10 dipswitches located on the serial board (dips 1 to 7), see the following fi gure (Fig. 3.n).

In the extended broadcast, the available addresses range from 1 to 15; setting 0 allows the address to be entered from the acqua terminal (see the section on “advanced settings”), in this way the system can be reconfi gured by simply connecting the terminal.

An extended broadcast installation can be easily converted to a hydronic system by modifying the serial addresses and setting a few parameters (see the section on “advanced settings” and “hydronic systems”).

e-drofan - +030221266 - rel. 3.6 del 26.04.2010

The following table shows the settings required to confi gure the corresponding addresses (binary notation):

Dipswitch setting

Address associated

Default=1 (serial address set from the acqua terminal)

1 2 3 4 5 6 7 8 9 10

Table 3.b

Dipswitches 9 and 10 are used to set the communication speed on the CANbus and must be both set in the same position.

dip 9 and 10 ON= 125 kbit/s dip 9 and 10 OFF= 62.5 kbit/s dip 8= must always remain ON for the use of the serial board on the e-drofan.

After each variation made to the position of the dipswitches, the e-drofan must be switched off and on again to make the changes operational.

The serial board is fi tted with three LEDs to display the operating status. The green LED indicates that the serial board is on (power from the e-drofan) while the yellow and red LEDs indicate the serial communication status. When starting, the two LEDs (red and yellow) come on together, in normal communication fi rst the red LED goes off, then the yellow LED, and fi nally the yellow LED (data reception in progress) or red LED (data transmission in progress) starts fl ashing. If both the LEDs are off steady communication is interrupted (the red LED continues fl ashing on the master).

3.3.10 Procedure for testing the installation and alarms

Once the installation has been completed, the test procedure can be run to check the devices. The terminal is required for these functions. To enter test mode press the UP and DOWN buttons for 10 seconds with the unit connected to the power supply and in off status; the event is signalled by the buzzer, which emits a beep.

The test proceeds in steps, indicated on the terminal by the message “L” followed by an incremental number; pressing the UP button proceeds to the next step (signalled by the BEEPING of the buzzer).

After the last step, the procedure ends and the controller returns to normal operation.

4. ADVANCED SETTINGS

In summary:

• General functions: inlet water temperature control;

• Algorithm to overcome the phenomenon of air stratifi cation;

• Manual operation: cooling, heating (heater management, if present), dehumidify, fan;

• Automatic operation (heater management, if present);

• Set point compensation based on the outside temperature;

• occupancy: possibility to use a second set point if the environment is not occupied (energy savings);

• control of modulating valves: three point or with 0 to 10 Vdc input.

The e-drofan provides a number of additional functions compared to traditional controllers: 5 digital inputs that can be confi gured, 3 probes, 1 dipswitch for rapid customisation on site, possibility of tLAN network connection and advanced control algorithms.

The e-drofan comes with a family of accessories (see the description in section “installer”) including: the acqua terminal (with NTC probe on board) or the remote control with corresponding receiver board, the expansion card with 4 relay outputs and the CANbus serial board for creating hydronic systems; as an alternative to the latter accessory, the 485 serial board can be installed to create customised (PlantVisor) or open (Modbus) connectivity solutions.

The following section shows, in sequence, the description of the parameters, from the confi guration of the I/O to the setting of the control algorithms. The list of parameters is shown at the end of the section.

Important: avoid parameter settings that create situations of confl ict (for example, do no not confi gure 2 digital inputs on the same e-drofan for economy operation).

4.1 Confi guration of the I/O and installer custom settings

The inputs and the outputs can be confi gured by parameter, thus giving the manufacturer complete freedom in choosing the available functions, while at the same time the installer can simply make the custom settings relating to the installation in progress (2 pipe, 4 pipe, etc.) using the dipswitches (see section “installer”).

The parameters may be set from: the acqua terminal, the programming key and the serial connection.

The following section shows some examples that help describe the controllable loads (fan, valves, heater etc.) and the corresponding confi guration of the parameters.

Example of fan coil installation in two pipe system:

4.1.1. Modifying parameters

To display and modify the parameters, enter editing mode by pressing, with the device OFF, the mode and clear buttons for 5 seconds (password 22) and then entering the second password for parameter

P92 (password 66). To restore the default values, set parameter P91 to the value 44 (with the device

OFF).

4.1.2 Probes

The probe readings are affected by the position of the fan coil (on the wall or the fl oor), due to the phenomenon of air stratifi cation. To overcome this problem, different offsets can be specifi ed, depending on the operating mode (heating or cooling). Faults with the control probe or one of the probes on the two exchangers will stop the fan and close the valve. By default the use of the probes must be set by dipswitch, nonetheless for the use of modulating valves and the P+I function, the probes can be set directly by parameter (the parameters must be set for all the probes and P95=1).

4.1.3 Digital inputs

Digital inputs DI1 and DI2 have a fi xed confi guration, while the remaining inputs can be confi gured by parameter. The off status of the digital input has priority over the signals received via the serial communication, so as to allow the user (directly affected by the fl ow of cold or hot air) to switch the fan coil units off. notes when the input is closed the unit is off (even in the event of network connection). In the transition from OFF->ON the e-drofan is started, but may subsequently be switched off from the terminal or via serial connection. In the off status, the valve is closed and the fan is stopped (after any post-ventilation phase required for the heater).

Below is a possible example for 0/10V modulating actuators on 4 pipe fan coils with heating/cooling request:

• output No4: P39= 13 modulating 0 to 10 V cold water valve output;

• output No5: P40= 14 modulating 0 to 10 V hot water valve output;

• output No6: P41= 3 cooling request;

• output No7: P42= 4 heating request.

Do not set modulating and non-modulating outputs at the same time (e.g. P39=1, P40=16 or P39=6 and

P40=17 etc.), as with modulating actuators control is P+I (when suitably confi gured); in any case, the following outputs can still be used: chiller activation signal, boiler activation signal and alarm. Only one output can be set as a heater.

In case of installations where the fan coils are used in stand-alone mode, the controller cannot know in advance the value of the temperature of the water contained in the loop, the probes being in the coil therefore afterwards the valves. After a series of attempts at fi xed time intervals, it is possible to detect the temperature through the parameter P51 setting, minimum opening time, and P52, preset waiting time.

A series of attempts are performed to activate the hot/cold water valve until the exchanger reaches the temperature required to activate the fan (cool/heat enable), in which case the cycle of attempts is reset.

The hot/cold water valve is activated for the time equal to P51 and remains off respectively for the time

P52 after the fi rst attempt, for P52-5 minutes after the second attempt, for P52-10 minutes after the third attempt, off for P52 x 2 after the fourth attempt; following the four attempts the cycle restarts from point

2 (valve OFF for P52 - 5 minutes).

In summary:

• General functions: Heat enable, Cool enable, Flush, Extra fl ush, autofan, continuous ventilation;

• Manual operation: cooling, heating (heater management, if present), dehumidify, fan;

• Automatic operation (heater management, if present);

• Set point compensation according to the outside temperature;

• Timer ON/OFF and SLEEP function;

• P+I control algorithm for modulating valves.

Below is a description of the operation of the e-drofan, divided into general functions, manual and automatic functions.

4.2.1 General functions: heat enable (heating/automatic heating)

In order to avoid undesired fl ows of cold air, the fan is only operated if the temperature of the main coil (probe B2) is high enough. If this condition is not satisfi ed the heating symbol fl ashes. DIP1 must be set to ON. The fan speed allowed (limiting the request by the control algorithm) is described in the following graph.

In order to avoid undesired fl ows of hot air, the fan is operated only if the temperature of the coil is low enough. If this condition is not satisfi ed the cooling symbol fl ashes. The DIP1 must be set to ON. The fan speed is managed by the control algorithms or set manually.

4.2.3 General functions: Flush (fan on/off cycles)

To overcome the phenomenon of air stratifi cation, the e-drofan operates fan on/off cycles at minimum speed, even when the room temperature has reached the set point (the local/hot/cold valve remains closed). This helps ensure the correct measurement of the room temperature if the probe on the acqua terminal is not used (control probe B1). If control is performed by probe BT, the fl ush function is disabled.

The behaviour can be modifi ed depending on the operating mode: heating, cooling, dehumidify or automatic. The fan is started after a period of inactivity (due to the set point having been reached or the heat enable or cool enable functions), equal to the value of parameter P32.

The local/hot/cold valve should be installed to use the fl ush function.

4.2.4 General functions: Extra Flush

This function ensures correct operation when the acqua terminal is not fi tted (control probe B1), overcoming the phenomenon of air stratifi cation.

Whenever switching from OFF->ON or changing operating mode, the e-drofan runs a fan cycle at minimum speed (for the time P35) to make sure the room temperature is uniform.

At the end of this interval, normal operation resumes. This is especially useful in the event of automatic operation. It is deactivated if probe BT on the terminal is used for the control functions.

The local/hot/cold valve should be installed to use this function.

4.2.5 General functions: Autofan (fan speed selection based on the room temperature)

The Autofan function establishes the fan speed when this is not set manually by the user.

In cooling and heating mode the speed is higher the more the room temperature deviated from the set point (including automatic cooling, automatic heating). In fan mode the speed is fi xed at the medium value for the range set by parameters P30, P31, P06 (see the paragraph below). In dehumidify mode the speed is fi xed at the minimum value.

4.2.7 General functions: Comfort

This function, if activated by P36, disables the modifi cation of the set point, allowing only an offset of +/-

3°C from the set value (in heat, cool, dry and automatic modes).

On the e-drofan master, the set point can be set via a serial connection (see the corresponding paragraph), while the slaves receive the set point from the related master and apply any offset (set from the terminal).

The master automatically loads the set point saved for parameter p01 when starting; this is subsequently modifi able via a serial connection. Set the logic and dependence parameters suitably.

E.g. In a hydronic system, the set point can be set on the e-drofan master and the slaves only allow modifi cations of +/- 3 C.

E.g.. In a centralised system (hotel), the room set point can be set via serial, allowing the guest the possibility to change it by +/- 3 C.

4.2.8 General functions: Occupancy

This function is used to set a second set point applied if the environment is not occupied, allowing the air-conditioning system to consume less energy and thus achieve cost savings.

The set point is increased by the value set for parameter P18 in cooling/dry mode, or decreased by the value set for P19 in heating mode.

Three typical situations have been identifi ed, represented by parameter P93 “occupancy type”; each type can be optimised using time bands (set via a supervisory system) and occupancy sensors. status of the installation occupancy type room status e-drofan operation event activating control at the set point

2. Occupancy timer reset when pressing the sleep button or activation of the occupancy digital input.

Table 4.j.a

• In all modes the change ON+ECO->ON or OFF->ON sets the “occupancy timer”, that is, on power-up the e-drofan starts with set point equal to the set value.

• In all modes (except corridor), holding the sleep button for 5 seconds the e-drofan takes set point= set value without time limits until receiving the OFF command; the set point may return to economy by pressing the sleep button again or switching the unit OFF or alternatively by disconnecting and reconnecting power to the e-drofan.

In a hydronic network the occupancy function shares the same variables as the economy/sleep functions, meaning the slaves can be forced to follow the status of the master (simply set the function on the master). In any case, the occupancy on a slave can be managed locally (obviously this must be fi tted with a terminal) by activating the function using the corresponding parameter; in this case the activation request

(following the detection of occupancy on the master) is ignored. symbol on master terminal

4.2.9 General functions: P+I algorithm (cooling/heating/automatic)

The e-drofan features a P+I algorithm that is used to control modulating valves with 0 to 10 Vdc input and

3 point valves.

Control can be performed on the BT probe on the terminal (room temperature, enabled by dipswitch 6) or on one of the three probes on the e-drofan (e.g. air intake temperature), by setting the corresponding parameter.

The P+I algorithm is activated by enabling one of the modulating valve outputs and setting the proportional band and integral time parameters.

Below is a diagram showing the use of the modulating valves in heating mode.

100%

6 6

4 5

Fig. 4.h.b

The proportional band determines the temperature range within which the actuator moves from closed to maximum opening with control by the proportional term only. The extent of opening depends on the proportional and integral factors; the proportional factor opens the valve further the more temperature is below the set point, while the integral factor increases the opening of the valve if the device takes a long time to reach the set point (with the temperature above the set point the behaviour is symmetrical, that is, the valve is closed).

Low values of the proportional band cause a fast and intense response but cause system instability (swings between opening and closing of the valve); setting low values for the integral factor offers a fast response but, in this case too, the risk of the system becoming instable remains. The integral factor compensates for any misalignments between the theoretical position and the actual position of the valve (this is phenomenon typical of 3 point valves after a large number of operations).

To correctly set the proportional band and the integral time, run some tests on the fan coil system in the environment being air-conditioned, simulating high load and low load conditions and the typical variations in load. One example of the values that can be initially used is: valve proportional band P115= 30 (3°),

P114= 30 (3°) and integral time P108= 60 (that is, 600 s).

A parameter is featured that limits the movements of the valve so as to reduce wear and adapt the P+I output to the effective resolution in the position of the actuator; in fact, a minimum variation in the P+I e-drofan - +030221266 - rel. 3.6 del 26.04.2010

output can be established before effectively switching the output (parameter P99).

Parameter P109 is the dead band (to the sides of the set point); within this zone the algorithm accepts minimum variations of the control temperature without performing any action, the purpose is to avoid instability and limit the number of operations of the actuator in steady operation (the integral factor remains constant, while the proportional factor is equal to 0). In cooling mode, the behaviour is symmetrical.

For the effective use of the actuators, the fan is activated when the P+I output is other than zero, the fan speed can be set manually or determined by the autofan function (in this case, at least the minimum speed is guaranteed).

The position of the valve can be displayed on the Acqua terminal in the place of the set point (see parameter P37).

If a series of actuators are used with overlapping set points and proportional bands, the activation is performed in sequence, starting from the resource with the lowest cost (e.g. valve) and ending with the resource with the highest cost (e.g. heater).

The “bumpless transfer” parameter is featured that, in response to modifi cations of the P+I algorithm control parameters during the normal operation of the unit, is used to dampen any swings or over-corrections of the system, especially if the algorithm interacts with a series of devices or actuators.

The P+I parameters are shown in the following table (for the settings corresponding to the various types of valves, see the following paragraphs).

4.2.10 General functions: modulating valve management

The management of modulating valves requires the algorithm P+I to be enabled.

Synchronisation

When the e-drofan is shutdown (switched from ON ->OFF), powered up, or when total closing is requested (in this case, the minimum time between two synchronisation cycles is 6 hours), a complete closing cycle is performed to ensure correct alignment between the position determined by the P+I algorithm and the real position, as there may in fact be misalignments due to mechanical wear after a signifi cant number of operations. The synchronisation procedure is only performed on the 3 point valves, while for the valves with 0 to 10 V input, the function is managed by the electronics on the actuator.

The return to normal operating conditions after a synchronisation cycle is managed according to the normal dynamics of the P+I algorithm, given that the extent of the error at the moment of synchronisation cannot be known.

Small deviations between the theoretical and the actual position are automatically compensated for by the integral factor.

Antistick

To prevent the valves from blocking (due to impurities or the entrainment of solid residues in the water circuit), set movements of the valve are performed periodically. These operations are effected only after a certain period in which the valve is inactive (for example, when the set point has been reached or when the device is off). For the valves with 0 to 10 V input, this function is managed by the electronics on the actuator.

4.2.14 Manual operation: dehumidify

Based on the set point set by the user, fi rst the room temperature is controlled, by cooling if necessary, and then the dehumidifi cation function starts.

In dehumidifi cation mode, the hot/cold water or only local/cold water valve is always open and fan on/off cycles are performed at minimum speed.

The cool enable function is always active to ensure that the temperature of the exchanger is low enough to ensure the condensation of the water vapour.

When the room temperature reaches the set point the dehumidifi cation function stops, the fan stops and the hot/cold water or only local/cold water valve is closed.

For modulating actuators, the valve is controlled as completely open or completely closed.

In this mode, the hot or cold water valve is always closed and the fan operates at the speed selected by the user (in autofan, it works at medium speed). The fan only starts if the room temperature is within the range of temperatures specifi ed by parameters P31 and P30, so as to avoid undesired fl ows of hot or cold air.

4.2.16 Automatic operation

In automatic mode, the e-drofan measures the room temperature and decides which mode to activate

(cooling or heating) based on the set point defi ned by the user, the criterion is described in the graph on the side.

The fan and local/cold/hot water valve are managed as in heating/cooling mode (the fl ush function is not active). The heater is also managed as in heating mode. In automatic OFF the local/cold/hot water valve is closed and the fl ush function is active. If when entering automatic mode the room temperature falls within the hysteresis, priority is given to heating mode.

COMFORT: This function, when activated, does not allow the set point to be changed (fi xed or sent via serial connection) but only the setting of an offset of +/- 2°C around the set point.

When cooling mode is activated, the control set point is equal to the set point + P02, while in heating mode, the control set point is equal to the set point - P03.

P+I ALGORITHM: Heating or cooling mode is determined according to the graph shown on the side, subsequently the P+I algorithm is activated to manage the outputs. The mode is changed only after the deactivation of all the actuators, as a consequence the internal parameters are reset each time. It should be noted that P02, P03, P04 and P05 ensure a further activation hysteresis (in addition to the P+I dead band) and consequently the parameters need to be set appropriately. The values of parameters P04 and

P05 should be set lower than the dead band.

4.3 Notes on the serial connection settings

A serial connection (PlantVisor or Modbus) can be used to check all the e-drofan parameters and set those that are not write protected. Below is a short description of the most signifi cant variables (for the settings see the parameter summary table).

Control probe

Set point setting

Control set point

Digital inputs and heat/cool request

Lock keypad from panel

Meaning

This variable contains the reading of the probe used to control the e-drofan (B1 or BT). The value

Type SV add Modbus add R/W

A 74 74 Read only considers any offsets, hysteresis values, control algorithms, etc.c.

Used to read and where required overwrite the value of the set point that has been set on the panel.

Especially useful if the e-drofan is operating with the comfort function active (e.g. centralised systems, such as hotels, offi ces, etc.) his variable is used to read the value of the set point used to control the e-drofan. The value considers

211

Read/write

Read only the hysteresis settings, compensation factors, offsets (e.g. SLEEP function), algorithms, etc.

Heat/cool request: the bits are set when the unit is in ON and the set point has not been reached.

Especially useful for energy saving functions.

Used to disable the buttons on the terminal to prevent accidental settings. Useful for centralised systems (hotels, offi ces etc).

Table 4.r

The hydronic network, if suitably confi gured, can disable some buttons on the terminal (see section

“hydronic systems”).

Enabling the TIMER ON and TIMER OFF functions (on the parameter P38) also enables the clock and the corresponding display (otherwise this is not visible).

4.4.1 Programming the events: timer ON, OFF and sleep

See the information in section “user” and the corresponding settings for the parameter P38. When the sleep function is active, in cooling mode, the set point is increased by the value set for parameter P18; in heating mode, the set point is decreased by the value contained in P19.

4.5 User interface (remote control and IR receiver)

The IR receiver board displays the status of the unit when the remote control is used. It also features a button for setting operation if the remote control is not available (e.g. fl at batteries); pressing the button repeatedly changes the mode, in the following sequence: automatic, cooling, dehumidify, fan, heating, off.

When setting the mode on the button the fan operates at minimum speed and the set point is equal to the value of parameter P01 (automatic mode set point).

5. HYDRONIC SYSTEMS

In summary:

• Synergy between chiller controller (pCO) and e-drofan;

• Algorithms focused on energy savings;

• Algorithms focused on comfort;

• Building automation functions;

• Flexible space management;

• Reduced times for the propagation of the commands;

• Type of networks: hydro bus (dedicated area controller or built into the chiller controller), integrated hybrid (area controller built into the chiller controller);

• Possibility to install the terminal on the slaves;

• Feedback on the alarms relating to the slaves (on chiller controller/area controller and e-drofan master);

• Control of all units by the supervisory system or area controller.

The use of the CAN serial board on the e-drofan allows the creation of hydronic systems with the purpose of creating synergy between the chiller controller (pCO) and the fan coil. This interaction gives the chance to apply advanced energy savings and comfort algorithms (resident on the chiller controller), as well as implement useful building automation functions.

The CAN board has been designed to minimise the activation of the operators in the event of variations in the spaces to be air-conditioned (quite common in some installations, e.g. offi ces); in this case, simply redefi ne the roles of the master and slave on the acqua terminal or pCO controller (if present).

5.1 Structure

The single node structure is used in the hydronic systems, in which the fl ow of data is bi-directional

(unlike the broadcast structure, in which it is mono-directional); there are many consequent advantages: display the slave alarms on the master, acquire useful values for the management of the system, fi t the acqua terminal on the slaves... etc.

The address set using the group of 10 dipswitches on the CAN board defi nes the operating mode: note

The address can be set on the acqua terminal, parameter P67 (switch off and on again to make the new setting operational); consequently, the mode can be confi gured. Without these settings P67=1 and the e-drofan fi tted with the terminal becomes the master.

Master and slave must have the same address

Each unit (master or slave) must have different addresses

After each variation made to the position of the dipswitches, the e-drofan must be switched off and on again for the changes to become operational.

In this mode, the information that the master must send to all the slaves (LOGIC parameter) can be set, as well as the information accepted by each individual slave (DEPENDENCE). The set of a master and its slaves is a “zone”. All the settings are performed on the master from the panel.

IMPORTANT:

Before modifying a parameter on the master (related to the confi guration of the network), the e-drofan must be set as a slave (P66= 0); once the operation has been completed, the e-drofan can be confi gured as the master.

The pCO chiller controller can deactivate some buttons on the e-drofan terminals via the hydronic network.

Following the setting of the DEPENDENCE parameter, a number of buttons on the e-drofan slave terminals are deactivated. These restrictions are required to avoid confl icts between the operation set by the master and any settings made by the user on the e-drofan slaves (using the acqua terminal).

Description of the LOGIC parameter:

• LOGIC 1: The same as the broadcast, with the addition of displaying the alarms relating to the slaves on the master terminal.

• LOGIC 2: Operation as per broadcast, with the addition of displaying the alarms relating to the slaves on the master terminal; all the e-drofans in the zone are controlled based on the probe value sent by the chiller controller (pCO). Useful for algorithms resident on the pCO.

• LOGIC 3: Operation as per broadcast (with slave alarms displayed on the master terminal) but data sent only at power-up of the master. Modifi cations can be made to operation by the user controlling the slave (e.g. change fan speed to reduce noise). Useful for aligning the status of the slaves in a zone with the corresponding master (e.g. Start-up in the morning).

• LOGIC 4: The master propagates ON/OFF, ECONOMY/SLEEP and control probe; all the remaining functions can be modifi ed on the slaves. The control probe reading is the average of the probes (B1 or

BT) on all the slaves in the zone. Useful for giving priority to control of the average temperature in an environment rather than single point control (see Fig. 5.2).

• LOGIC 5: Operation as per broadcast (with slave alarms displayed on the master terminal). The master propagates different set points for each slave (these can be set on the master terminal). Useful in zones featuring slaves without terminals.

• LOGIC 6: Operation as per broadcast (with slave alarms displayed on the master terminal). The master propagates different set points for each slave (these can be set on the master terminal as offsets from the set point). Useful in zones featuring slaves without terminals.

• LOGIC 7: Reserved for future uses.

The off status, determined by ON/OFF digital input, has priority over the command sent by the master; this operation is required to allow the user to turn off the fan coil to stop the fl ow of cold air.

The area controller/chiller controller can nonetheless force the settings on the e-drofan irrespective of the dependence setting (useful in some extreme situations) and can acquire some useful information

(status of digital inputs, heating/cooling request...etc.); for this information and for the further algorithms

(comfort, energy savings.. that reside on the chiller controller (pCO)), refer to the corresponding user manual.

IMPORTANT:

If communication is interrupted between a slave e-drofan and its master (e.g. disconnection ...etc.) the slave stops automatically, nonetheless, it can be re-activated if fi tted with the acqua terminal or remote control (in this case, the device has full control over all the functions).

In these applications (typical in single homes) the chiller controller (pCO) carries out the functions of both chiller management and area controller (that is, sends the commands required for the management of the units connected in the network and monitors the status). A maximum of 16 e-drofan masters can be managed by the chiller controller.

e-drofan - +030221266 - rel. 3.6 del 26.04.2010

5.1.3 e-drobus

If only the CANbus connection is used, there is still the possibility to create networks in which the pCO acts as both chiller controller and area controller (that is, manages the 16 masters connected in the network).

To exceed the limit of 16 master units (necessary for multi-storey buildings), systems must be adopted in which one pCO only acts as area controller, while the chiller is controlled by a dedicated device

(connected to the area controller, e.g.: pCO, µCH2).

In this case, a maximum of 64 e-drofan masters can be connected to the area controller, and the remaining units (up to a maximum of 100) can be assigned as slaves to the e-drofan masters. The area controller has complete control over the masters directly connected, while as regards the slaves assigned to the master, it can only act on the related logic and dependence parameters (resident on the master).

Fig. 5.e

5.2 Signals and diagnostics

The CANbus serial board has three LEDs to display the serial communication status relating to the device it is installed on.

The green LED is always on when power is connected.

When the board is initialising, the red and yellow LEDs fl ash in specifi c sequences. After around 20s, when initialisation is complete, the following situations may occur: green LED yellow

5.2.1 Alarms

The acqua terminal displays the alarms on the e-drofan it is connected to, as well as those on the corresponding slaves. When it displays the alarms on its own e-drofan, the signal starts with “A” (e.g. A04), while when displaying those relating to the slaves in the zone, the signal starts with “S” (the second number indicates which slave it refers to (from 0 to 9), while the third number indicates the alarm code).

The codes for the slave alarms (third number) are the same as described in section “constructor”, with Sn0 add: (n = Slave address): Slave not present.

The alarms on the master have priority over the slaves (see section “constructor”), the alarms on the different slaves are displayed in sequence (for each slave, the alarm with the highest priority is displayed).

The e-droset terminal only displays the index of the slave with the alarm.

1. slave alarm;

2. slave;

3. room probe fault.

5.2.2 Notes on confi guring hydronic networks

During the confi guration of the hydronic networks, the following instructions should be observed:

IMPORTANT:

Avoid settings that create situations of confl ict.

3 note description

1 If confi guring a series of e-drofans, fi rst confi gure the slaves and then the corresponding master, or alternatively perform the settings with the CANbus disconnected.

With logic 5 and 6 do not connect the acqua terminals on the slaves.

The logic must be set on the master before the dependence on the slaves.

Some functions can be activated both locally (digital inputs) and remotely (via serial connection). To avoid confl icts, install the ON/OFF, ECONOMY and PRESENCE digital inputs only on the e-drofan master. The slaves can only be connected to the inputs relating to the alarms

(window alarm, circulating pump alarm and local stop).

related events

If this sequence is not observed, some buttons on the terminal connected to the slave may be locked due to of the dependence set on the master, thus preventing the correct confi guration of the slave/slaves.

The information propagated via the CANbus may be lost.

The related parameters (dependence P81-P90) may have different meanings

(see logic 5 and 6) when the logic changes. When logic is 5 (different set points) the limits are 7 to 35°C, when logic is 6 (offset from the set point on the master) the limits are -5 to +5.

The status of an e-drofan slave is continuously controlled by its master. The master is set by the area controller/chiller controller just once, which allows the subsequent modifi cation of its status (e.g. from the presence or ON/OFF inputs etc.). The continuous or periodical control of the master must be included in the area controller/chiller controller application.

In the event of confl icts between the digital input and the area controller/chiller controller, operation is not affected, however there will be intense traffi c in the serial communication, causing a decline in performance.

So as to avoid confl icts, the cooling/heating function (to be installed on the master only) must be set only by digital input or via serial communication.

The same must be applied to the remote off (settable by dipswitch).

In this regard, the dependence is set to 0 when DIP 2 or 3 is ON (only when starting), while there is still the possibility to change the dependence from the area controller/chiller controller.

The specifi cations provided for the acqua terminal are also valid when using the remote control, with the exception of the keypad lock. In fact, if a function is locked, the remote control still sends the data, which are however ignored by the e-drofan; consequently, there may be discrepancies between the information shown on the display of the remote control and the operation of the device.

The slaves should be fi tted ON/OFF digital inputs (without acqua terminal or remote control, or if ON/OFF is disabled). In this way, the user can switch the unit off to stop the fl ow of hot/cold air.

Table 5.f

5.2.3 Notes on the serial address settings

The serial address in a CAREL or Modbus ® network is assigned by the e-drofan board using parameter

P69 “local network address”.

In a CANbus network, on the other hand, the device network address is assigned by parameter P67

“CANbus serial address”. For correct communication between the CANbus serial board and the e-drofan, parameter P69 must be set to 1 (this is the default setting).

6. NON-HYDRONIC SUPERVISORY SYSTEMS

6.1 Introduction

The 485 serial board can be used to create customised supervisory systems, for example PlantVisor.

The same accessory can be used to integrate the e-drofan into ModBus systems (enable Modbus with parameter P54= 1).

6.2 Easy way Acqua (wireless network)

The “Easy Way Acqua” system is an evolution of the e-dronic system. Exploiting ZigBee wireless technology, this system ensures communication between e-drofan devices without a wired network. The e-drofan interfaces to the wireless system by fi tting a router board that acts a gateway on the supervisor serial connection.

The logic implemented in the Easy Way Acqua system is similar to tLAN and CANbus broadcast mode, as the different e-drofan devices in the same hydronic zone have identical behaviour.

In the Easy Way Acqua system, the main hydronic zone operating parameters are always accessible to the supervisor.

For details on operation of this system, see the corresponding manual.
