Room auiomation solution

1 Overview

1.1 Room automation solution with SBC Serial S-Net or L on

W orks

®

The PCD7.L6xx room controllers, based on SBC Serial S-Net, LonWorks

BACnet

®

®

or

MS/TP networks, are mainly used for HeaVAC applications with FanCoil devices, radiator/cooled ceiling combinations or VVS systems. The extension module for light and shade allows the electrical systems to be easily integrated in to the room automation solution. Customer-specific operating concepts can be produced with the wide range of room control units. these room control units are connected to the room controller by cable, infra-red or wireless receivers.

Manufacturer-independent room control units

Control units with L on

W orks

®

communication can be connected directly to the

LON room controllers. To connect EnOcean room components there is a receiver module that can be connected directly to the room controller via the internal RC bus.

If the user control requirements should still not be met in terms of form, design or functionality, the system integrator can use the open interfaces to the automation station or analogue room control units to combine the room controller with third-party systems.

1.2 Possible uses for the PCD7.L6xx series

1.2.1 Standalone control with no communication

The controller regulates the room temperature without any connection to a bus system. Control is handled entirely by the individual room controller based on the specified default parameter settings.

The outputs are driven by a control algorithm depending on the measured temperature.

The default set-point setting of 21 °C can be modified by the set-point control (according to the device).

1.2.2 Standalone control with communication to the automation station

The controller is run as a slave station with a unique Bus address within a SBC

Serial S-Net, L on

W orks

®

or BACnet

®

network.

Control is handled by the individual room controller with its own control algorithm.

The control functions - time or event-driven - are passed to the individual room controller by the automation station via suitably configurable function objects or network variables. This supports individual parameterisation and operation of the room controller. The device, and hence the control function, can also be influenced at any time via the Saia PCD

®

master station.

For parameterisation, there is a function object available in the library for every room controller type. In the case of open network connections, this is handled via network variables or network objects.

Commissioning instructions

Safety instructions


Safety instructions

To guarantee safe operation, the PCD7.L6xx devices should only be operated by qualified staff according to the details given in the operating instructions and in compliance with the technical data. Qualified staff are people familiar with the assembly, commissioning and operation of the devices and suitably trained for their job.

When using the system, the legal and safety regulations applicable to the specific type of use must also be observed.

The room controllers have undergone a comprehensive pre-delivery inspection, ensuring that they left the factory in perfect condition.

Before commissioning, the devices should be checked for damage arising from incorrect transport or storage.

Removal of the identification numbers will invalidate the warranty.

Please ensure that the limits specified in the technical data are not exceeded. Failure to do so may result in defects in the modules and the perpiherals connected to them.

We can accept no responsibility for damage arising from improper deployment and use.

The plugs must never be inserted or removed with the power on. When installing or de-installing the modules, all components must be switched off.

Please read this manual carefully before assembling and commissioning the modules. This manual contains instructions and warnings that must be observed to assure safe operation.

Assembly instructions

Assembly instructions

■ The individual room controllers must only be installed and connected by an expert in accordance with the wiring diagram. Existing safety standards must also be observed.

■ The individual room controller can only be used to regulate the temperature in dry, closed rooms. The maximum permissible relative humidity is 90%, noncondensing.

■ Precise temperature measurement is subject to certain requirements as to the positioning of the temperature sensors. This applies both to the room control device itself and to the externally connected temperature sensor.

■ The device can be mounted directly on the wall or flush-mounted within a pattress box.

Avoid direct exposure to sunlight or light from powerful lamps.

2

Do not install next to windows and doors because of draughts.

Do not install next to heat sources such as heaters, refrigerators, lamps etc.

Please ensure

● that all wires are screwed down tight

● that the connecting plug is properly engaged

● that the ventilation slots are placed above and below (positioning)

● that the device is mounted horizontally.

3.1 Communication

3.1.1 Functions, commissioning

Automatically detecting the SBC Serial S-Net baudrate

After the current is switched on, the room controllers attempt to detect the baudrate on the S-Bus for themselves. During this time, the controller does not function. For this, it is necessary for the communication master to send telegrams on a cyclical basis. Where a Saia PCD

®

is used, this task is handled by the "Setup" FBox from the "PCD7_L60x room controller" group. Once the room controller has detected the baudrate, it stores this information. After a restart, it will begin by setting this baudrate. Only when the room controller cannot establish any communication with the last used baudrate does it restart baudrate detection.

3

The picture shows a SASI interface initialisation and the Setup FBox.

The activated Setup FBox makes cyclical attempts to establish a connection to station address 252 (see service pin on the room controller). As the service pin is not normally activated on any room controller, station address 252 is not present. The

LED for the SASI S-Bus master FBox is then red.

After successful commissioning of the room controllers, it is therefore advisable to deactivate the Setup FBox via the "Enable" input. If proper communication is established, the LED for the SASI S-Bus master FBox should stay green.


3-1


Function

Communication

Setting the SBC S-Bus service pin

When the "Service pin" button is pressed, the room controller enables an additional station address 252 for a minimum of 15 minutes. The controller can use this address to communicate with the master independently of all other software components.

Provided that the room controller is receiving telegrams via this address, the timer for time monitoring is restarted each time. Only when the timer expires (after 15 minutes) is station address 252 deactivated.

Please note that two controllers cannot be activated at the same time via the service pin.

3

To terminate the timer prematurely, register 60 can also be manually set to 0, e.g. via the Setup FBox, a communication FBox or the debugger.

Function

Communication

Setting the station address

The station address can be parameterised via the Setup FBox or directly in register

Function

Communication

Automatic configuration

The room controllers can be configured automatically via the Config and Room

FBoxes. After every restart, a flag is passed to the Room FBox to tell it that the controller has been restarted. The FBox then checks that the configuration matches the associated Config FBox. If this is not the case, all the control parameters are copied over automatically from the Config FBox to the room controller. This option reduces commissioning to the address-setting operation. This means that after a device replacement in the course of support work, functionality can be reliably restored by the Saia PCD

®

alone.

Functions, settings

Functions, settings

The L60x room controllers have an integrated, parameterised control program. The parameters can be used to define the behaviour of the individual functions such as the room control unit, hardware, regulation and light and shade.

The settings can be entered automatically or manually via the "Config" FBox, or set via individual S-Bus registers. This constitutes configuration using the Config FBox.

The associated registers and their values are shown in tables in the appropriate places.

Use of the "Config" FBox

Enable

With the "from station address" and "to station address" parameters, a range of

S-Bus addresses can be defined for which the subsequent configuration applies.

Where automatic configuration is used, the Config FBox will automatically copy the configuration to all stations in the range.

If automatic configuration has not been activated, the configuration can be written manually by pressing the "Write" button on the controller with S-Bus address "from station address", " to station address".

The current contents of a controller can be displayed in the online parameters by entering the S-Bus address in the "from station address" parameter and then clicking on the "Read" button.

All parameters can also be written individually as registers without using the Config

FBox.

All 4 light bands can be assigned to up to 4 independent groups of lights. A blind control comprises a relay for "Up" and one for "Down". Each of the 4 blind outputs can be used to control up to

4 independent groups of blinds. It is immaterial whether an output is used in multiple groups, or not at all.

The function is controlled via a room control unit with display (PCD7.L644), a mobile control unit with IR or wireless interface, and/or with the S-Bus master. Switching instructions are always given to the group and not to the individual output. This provides a high level of flexibility, e.g. on a North/South axis.

A configuration parameter (register 101) can also be used to make ventilation independent from the mode. This allows one to specify e.g. that in winter, only heating is possible, and in summer, only cooling (see Config FBox hardware, ventilation mode).

Parameter to set a specific operating mode (register 36).

1, Reduced The mode can be set to Comfort for a definable period via the room control unit or the communication function (see Function, setting, control parameter register 0). At the end of this time, the mode automatically switches back to Reduced operation.

2, Standby When a presence is detected by a room control unit or the communication function, the controller switches to Comfort mode.

Where no presence is detected, the controller switches directly back to Standby mode.

0, Comfort The controller switches directly to Comfort mode.

5, Permanent The controller works permanently in "Reduced" mode. The

"Reduced" Presence detection is deactivated. This mode is especially suitable to maintenance and service activities at times when the room is not in use. With on-demand systems, this makes it very easy to prevent the whole installation, including climate control, from switching on when not required.

Function

Functions, manual output control

3.7.1 Concept

As a rule, the channel reference of the RS485 interface and the S-Bus station address of the desired room controller are parameterised in the Room FBox. The Room

FBox can then communicate with the room controller. The "L60x AO", "Light" and

"Sunblind" FBoxes can be attached to the Room FBox. For this, an FBox name must also be configured in the Room FBox. NOTE: The name must be unique within the project. The room name is then entered as a reference into the "L60x AO", "Light" and "Sunblind" FBoxes.

3.7.2 L60x AO, analogue outputs

The "L60x AO" can be used for remote control (RIO) of outputs not used by the selected application. See sections on "Functions, settings, application" and

"Functions, settings, hardware".

3.7.3 L60x AO, definition of output

Defines the output to be controlled.

All outputs are basically analogue outputs. Outputs Y3 and Y4 work proportionally with 0-10V. The switching elements such as Triac (Y1 and Y2) and the relay contact output (K1/K2) are pulse-width modulated (PWM). The cycle time is entered in the hardware settings. Values between 0.1 and 99.9 define the pulse/pause ratio. A value of 0 switches off a PWM output permanently, while 100.0% keeps it switched on.

The internal parameter "Send value" is used to determine the communication

Function

Functions, manual output control behaviour of the FBox. The value at the input can be transferred to the room controller cyclically or only after a change of value.

For a transfer after a change of value, the "Hysteresis" parameter defines the minimum change to the input value (compared to the last value sent) required to trigger a fresh communication.

Regarding the maximum outputpower for 24 V outputs of the PCD7.L604 controller, attention should be paid to the technical data PCD7.L604 in chapter 6.2.5 .

3.8 Functions, master/slave

Function

Functions, master/slave

3.8.1 Concept

In master/slave operation, it is possible to use one (master) room controller to control other (slave) controllers remotely. For this, the master simply uses the outputs from the slaves to control conditions in the room.

Master/slave operation is generally implemented via the Room FBoxes. The master/ slave system used here is then so flexible that a Room FBox only has to be told which S-Bus station address is the master for this room controller. Many controllers can also be chained together. This allows e.g. a slave to be the master for another device etc. A typical application would be in rooms that can be divided in different ways, e.g. meeting rooms in conference facilities.

The master controller transmits its output signals for heating valve, cooling valve, electric reheating and fan speed to the slave. The hardware configuration in the slave then decides in turn which outputs should actually be used. As described above, the unused outputs in the slave can also be controlled independently via the S-Bus (RIO).

3.8.2 Room, master/slave parameters

The "Room controller working" parameter is used to define the operating mode as

Master = "standalone" or Slave = "as slave".

In "as slave" mode, the master station address also has to be entered.

In the "Master" function, the parameter "Master station is station" has no meaning.

3.9 Functions, light and shade

3.9.1 Concept

As a rule, the channel reference of the RS485 interface and the S-Bus station address of the desired room controller are parameterised in the Room FBox. The

Room FBox can then communicate with the room controller. The "L60x AO", "Light" and "Sunblind" FBoxes can be attached to the Room FBox. For this, an FBox name must also be configured in the Room FBox. NOTE: The name must be unique within the project. The room name is then entered as a reference into the "L60x AO", "Light" and "Sunblind" FBoxes.

3.9.2 L60x Light, light control

3

The "L60x Light" FBox can be used to switch up to 4 independent light groups. The individual light outputs are assigned to the groups in the configuration. See section on

"Function, settings, light"

The FBox inputs only react to a change of value. The internal parameter "Send value" currently has no effect. To assure compatibility with future versions, "Value change" should be set.

In the FBox, Light master/slave operation can be defined independently of the Room

FBox. If the FBox is configured as a slave, the Blind outputs are passed to the slave after a change of value on the master.

Definition of master/slave mode Slave; standalone light control

Function


3.9.3 L60x Sunblind, blind control

3

The "L60x SB" FBox can be used to switch up to 4 independent blind groups. The individual up/down outputs are assigned to the groups in the configuration. See section on "Function, settings, blinds"

The FBox works on the "read/modify/write" principle. After a change of value at one of the FBox outputs, the current blind status is read from the controller. The information read is modified according to the changed inputs. Data where the associated

FBox inputs have not changed are retained. The new status is then returned to the controller once more.

“Send value”

The FBox internal parameter "Send value" currently has no effect. To assure compatibility with future versions, "Value change" should be set.

Function


“Lighting control in operation“

In the FBox, Blind master/slave operation can be defined independently of the Room

FBox. If the FBox is configured as a slave, the Blind outputs are passed to the slave after a change of value on the master.

Example applications


General

The programming of the PCD7.L60x product family presented here uses the SBC

"RoomControler PCD7_L60x" FBox family. The library is supplied by SBC free of charge, and can be obtained from Saia-Burgess Controls AG in Murten.

At start of project, the HeaVAC library and the serial interface need to be initialised.

The picture shows the configuration for a PCD3 using the integrated serial RS-485 interface "Channel2".


4-2


Configuration


4

The room controllers can be parameterised very efficiently. Where a set of room controllers with consecutive SBC S-Bus addresses are to be configured with the same basic parameters using the Autoconfiguration function, a single Config FBox can distribute the parameters to all the room controllers automatically. To do this, the start and end addresses are entered into the Config FBox in the "from station address" and "to station address" parameters and "Autoconfiguration" is set to

"active".

Configuration can also be carried out manually. To do this, the "Autoconfiguration" parameter is set to "inactive". The "Write" button then causes the whole parameter set to be copied over to all station addresses from "from station adddress" to "to station address".

If a station address within a selected range was not configured successfully, the

Config FBox interrupts Autoconfiguration at this point and displays "Error" in the right of the window next to the Write button, with the relevant station number below.

When writing, whether automatically or manually, all parameters are stored directly in the room controller's EEPROM. The previous settings are then lost.

To read the parameters, it is sufficient to enter the SBC S-Bus address in the "from station address" parameter. The "Read" button causes the data to be passed from the room controller to the FBox.


4-3


Function


4

In order to use the Autoconfiguration function or individual communication with a room controller, one Room FBox per room controller is required. See section on

"Functionality, actual values". The room controller can then operate standalone (as a master) or as a slave.


4-4


Control of free outputs


Free outputs, i.e. outputs not used by the selected application (see Configuration), can be controlled at will via the Saia PCD

®

. This requires the use of a Room FBox with a unique FBox name. The outputs are passed to the Room FBox by the analogue output FBoxes. The Room FBox is entered into the analogue output FBox as a reference. (See also "Function, manual output control".)

Regarding the maximum output power for 24 V outputs of the PCD7.L604 controller, attention should be paid to the technical data PCD7.L604 in chapter 6.2.5 .

Remote IO


Instead of standalone control operation, internal regulation and control can also be completely disabled. The outputs are then dependent only on the communication master. For this RIO (remote input-output) operation, the RIO FBox is provided.

The new room controllers from hardware version 1.2 have a high impedance and place only a small load on SBC Serial S-Net. They have an 8x higher impedance than the old room controllers (hardware version 1.1 and older) or a standard receiver.

Limited by the electrical load on the SBC Serial S-Net system, a segment (without repeater) can have no more than 32 Saia PCD

®

controls, or 31 .L60x room controllers with hardware version 1.1 and older, or 248 room controller with hardware version 1.2 connected to it.

The overall power consumption of the valves have to be a maximum of 7 W. This should be noted particularly for applications where multiple valves are considered to be controlled simultaneously. If the accumulated power consumption of the valves in the planned configuration is beyond 7W, there are two possibilities: the use of valves with low power consumption or the use of the 24 V

Terminal

RC

Description

The PCD7.L679 is connected to the room controller with the PCD7.L670 directly to the controller, or where extension modules are used for light and shade, to the last module. The

PCD7.L670 connecting cable is preconfigured at both ends and is 10 m long. The maximum length between the room controller and the room control unit must not exceed 11 m.

Configuration

The parameters are selected by entering a letter and a numeric code. Parameters in group "L" can be read, while parameters in group "E" can also be modified.

The module starts up when it is connected to the the room controller in the read group with the first parameter, and display shows "L.01".

The small round button is used to switch between reading end editing parameters.

The arrow keys are used to select the desired parameter. The parameter is retrieved with the oval key. Pressing the key again returns to the parameter selection menu.
