ADVANCED FUNCTIONS

1.- REMOTE ON/OFF

This function allows you to turn the unit on/off by a simply remote contact :

• Contacts 95-96 for ECOLEAN and AIRCOOLAIR units,

• Contact 890-891 for HYDROLEAN,

• Contacts 88-89 for AIRCUBE units

Close contact = ON; Open contact = OFF.

2.- REMOTE CHANGEOVER WINTER/SUMMER

On heat pump units (HYDROLEAN and AIRCOOLAIR in cooling only + electrical heater), cooling or heating mode can be selected by a remote contact :

• contacts 97-98 for AIRCOOLAIR units

• Contact 892-893 for HYDROLEAN units

Close contact = Cooling.; Open contact = Heating.

To activate this function set parameter H06=1.

WARNING

On Aircoolair units, remote changeover doesn’t work if the automatic mode has been selected by DC40.

3.- DYNAMIC SET POINT

OPTION

With this function, which needs to incorporate an additional outdoor temperature probe, it’s possible to adjust the set point dynamically based on ambient temperature.

The set point value can be increased or decreased when the external conditions are more advantageous, thus achieving extra energy saving.

Dynamic set point must be activated in the factory.

The user must set the parameters as shown in the graphics below:

4.- BMS COMMUNICATIONS

OPTION

Given the growing and unstoppable trend towards Building Automation, driven by powerful and ever-evolving connectivity, the Climatic

40 controller offers the possibility of communicating with Building Management Systems (BMS) via Modbus protocol.

The Modbus standard interface is integrated into the control, so you don’t need any sort of gateway, router, etc.

In order for you to connect to the RS485 serial line, we provide the TTL-RS485 converter as an option for Ecolean and Aircube units.

Aircoolair units don’t need the converter (it’s integrated) but they do need the ambient or duct remote sensor option.

MODBUS

ECOLEAN

AIRCOOLAIR

For further information, please see BMS communication manual.

5.- TIME BANDS PROGRAM (Ecolean)

The Climatic 40 controller allows 2 time bands to be programmed for each day, each with a different set point.

EAC + kit -15ºC y EAR 251-812 SM

ANCM + kit -15ºC y ANHM 22E-86D

KSCM + kit -15ºC y KSHM 22E-86D

This function moves the condensing pressure set point in order to lower the fan speed and thus reduce noise (specifi cally at night).

If low noise is active during cooling, the condenser control set points are increased by 5º bar. If low noise is active in heating, the set points are reduced by 1º bar.

Set F15=3 to active this function.

WATER PUMP- WATER FLOW SWITCH (ECOLEAN / HYDROLEAN)

The water fl ow switch ensures that the water pump does not work when there is no water fl ow. At fi rst, there is a by-pass during the fi rst

150 seconds of water pump operation which operates according to the water fl ow switch signal. When the alarm has been activated, the water pump is stopped. The water pump starts again every 90 seconds for 150 seconds, in order to try to reset the alarm. This procedure is repeated 5 times and after that the pump remains stopped until the alarm is reset manually.

9.- DEFROST (HYDROLEAN)

The defrosting process is activated during heating mode in the heat pump units, when the outside temperature is low and the outdoor coil is likely to be frozen. To melt the ice, the defrosting function will switch the unit to cooling operation for a short period.

During defrosting mode, the low pressure is at minimum level, so the pressure switch is disabled in this mode.

The defrost cycle is illustrated in the following picture.

If the pressure does not reach 30/35 bars within 8 minutes from the start of the defrost cycle, the cycle fi nishes because of maximum time and the display shows “dF1” or “dF2” (according to the circuit).

The time between two defrost cycles for the same circuit is 40 minutes. The time between two defrost cycles of the two circuits is 10 minutes.

10.- CONDENSER FAN SPEED CONTROL (EXCEPT HYDROLEAN)

The function of the fan speed control is to prevent very low condensing temperatures during cooling mode operation at outside temperatures of between 0ºC and 46ºC.

Depending on the unit, this function could be:

1.1.- PROPORTIONAL CONTROL BASED ON PRESSURE

Models: ECOLEAN: . . . . . . EAC + kit -15ºC and EAR 251-812 SM

AIRCOOLAIR: . . . ANCM + kit -15ºC and ANHM 22E-86D

AIRCUBE:. . . . . . . KSCM + kit -15ºC and KSHM 22E-86D

In this case, it is a proportional fan speed control, which varies the fan voltage supplied to the fan.

NOTE

At start-up the fan works at maximum speed for 20 seconds, so as to overcome the mechanical inertia of the motor.

The fans for these models incorporate 2 speeds. The fans work on high or low speed according to :

COOLING MODE:

The on/off and low/high fan speed is managed according to the condensing pressure. See the illustration below:

11.- FREE COOLING (AIRCOOLAIR)

OPTION

This option takes advantage of external conditions for cooling mode.

Freecooling is enabled when outdoor temperature is 1ºC lower than indoor temperature; when the former is:

• < 10ºC, the compressors are deactivated and the air intake gate fully opened in order to refresh with outdoor air only (suffi cient under these conditions).

• >10ºC, the air intake gate opens and delays the compressors, which turn on only if there would be insuffi cient outdoor fresh air to achieve the comfort setpoint.

The illustration below shows freecooling regulation.

SAFETY DEVICES

ANTIFREEZE PROTECTION (ECOLEAN / HYDROLEAN).

This protection is activated by the control of the unit when the outlet water temperature probe (b2), located inside the water exchanger, measures +4.5ºC and deactivates when the outlet water temperature probe reaches +5.5ºC again.

When the protection is activated, the following occurs:

- If the unit is operating in STAND-BY mode: the water pump goes on, as does the electrical heater for the water exchanger and the electrical heater of the water tank (if included).

DO NOT TURN OFF THE POWER TO THE UNIT. WHEN THE POWER IS OFF THE ANTI FREEZE PROTECTION WILL

NOT OPERATE.

- If the unit is operating on cooling mode: it powers the electrical heater of the water tank, the electrical heater of the water exchanger, and it activates the hot gas injection valve (if the unit incorporates these options).

LOW WATER TEMPERATURE ALARM (ECOLEAN / HYDROLEAN).

This alarm is activated when the outlet water temperature probe (b2) measures a value of + 3 ºC (in standard unit).

The unit is stopped. The alarm can be reset manually when the outlet water temperature reaches + 8ºC (in standard unit).

NOTE : Low water temperature options can change the values of antifreeze protection and low water temperature alarm.

ANTIFREEZE PROTECTION (AIRCOOLAIR).

The unit is protected by means of a temperature probe located in the indoor piping, when the indoor temperature goes drops 2ºC:

WITHOUT FREECOOLING

- The compressors shut down and the antifreeze alarm goes on.

- The alarm is reset automatically when the temperature reaches 7ºC.

WITH FREECOOLING

- Air intake gate closes,

- Once the gate is completely closed, the compressors shut down and the antifreeze alarm goes on.

When the air intake gate is closing, if the temperature in the indoor piping goes up 2ºC, the gate stops and stays in the position reached; then, if the temperature reaches goes over 7ºC, the air damper starts to open or, if the temperature goes down 2ºC, the damper start to close again.

In addition to that, in order to prevent frozen air discharging when freecooling without the compressors working (outdoor temp. <10ºC), if the temperature in the indoor piping goes down 7ºC, the air intake gate starts to mix outdoor air with return air, thus increasing the temperature of the discharge air.

ALARMS

ALARMS/WARNINGS DISPLAY

The unit self-protects by means of safety devices; when any of these safety devices detects an anomaly, this is shown on the Climatic

40 display and, in Aircoolair units only, also on the DC41 display (even if it has a different alarm code), in order to warn the operator.

Depending on the type of anomaly, Climatic 40 shows:

• Alarm. Serious anomaly. This is one that has a direct effect on the operation of the unit.

• Warning. Non-serious anomaly. This is one that has no direct effect on the operation of the unit.

The activation of an alarm results in:

- Alarm code being shown on Climatic 40 display alternately with the main menu.

- Only in Aircoolair units, an alarm code (different from the one for the Climatic 40) being shown on the DC40 display alternately with the main menu.

- A red bell appears on the Climatic 40 display and the alarm relay is activated. (contacts 99-100).

- In some cases, depending on the type of alarm, some of the outputs may be blocked, thus stopping the unit.

The activation of a warning results in:

- A warning code being shown only on the Climatic 40 display, alternately with the main menu.

ALARM/WARNING RESET

Some alarms are reset automatically. When the cause is no longer present, they disappear from the display.

Others alarms are reset manually and, once the alarm conditions have disappeared, they need to be reset by the user as shown below:
