CONTROL DESCRIPTION
DC41 terminal is an optional keypad that allows to manage Climatic 40 controller from a remote position. The buttons and
indications on the display faithfully reproduce the Climatic 40 user interface.
1.1.1.- TURN ON/OFF THE UNIT
In order to turn on the unit, press for 2 seconds the “ ” button, for the heat pump mode, or the “ ” button, for the cooling
mode.
The display shows unit’s operating mode together with the symbols of the working elements (compressors, water pump etc.).
In order to turn off the unit, press for 2 seconds the “ ” button (if the unit is working in heat pump mode) or the “ ” button (if the
unit is working in the cooling mode).
1.1.2.- SELECTING THE UNIT´S OPERATING MODE
If the unit is in stand-by, the operating mode is selected in the start-up (as explained above).
In the case the unit is working in cooling or heating mode, in order to change the operating mode, you have to turn off the unit
before, and only then you can turn it on in the operating mode you want.
1.1.3.- SELECTING THE WATER TEMPERATURE OF THE SYSTEM
To modify unit working set point you have to change r1 parameter (cooling set point) or r3 parameter (heating set point).
To see how to change a parameter see chapter 3 MENU (SETPOINT SETTINGS AND OPERATING HOURS DISPLAY MENU
paragraph).
1.2.1.- TURN ON/OFF THE UNIT
The unit turns on closing On/Off contact and turns off opening it (see section 1, advanced functions, for more details).
1.2.2.- SELECTING THE UNIT´S OPERATING MODE
Heating mode is selected opening remote changeover contact while cooling mode is selected closing it (see section 2, advanced
functions, for more details).
NOTE
Set point has no meaning in Aircube units because the compressors are directly controlled by remote contacts.

ADVANCED FUNCTIONS
1.- REMOTE ON/OFF
This function allows you to turn on/turn off the unit by a simply remote contact (contacts 95-96).
Close contact = ON; Open contact = OFF.
2.- REMOTE CHANGEOVER WINTER/SUMMER
On heat pump units (also in Aircoolair cooling only + electrical heater), it is possible to select cooling or heating mode by a remote
contact (contacts 97-98).
Close contact = Cooling.; Open contact = Heating.
To activate this function set parameter H06=1.
3.- DYNAMIC SET POINT
With this function, which needs to incorporate an additional outdoor temperature probe, it’s possible to have a dynamic adjustment
to the set point based on ambient temperature.
The set point value can be increased or decreased when the external conditions are more advantageous, so an extra energy sa-
ving can be achieved.
Dynamic setpoint must be activated in the factory.
User must set the parameters as shown in the graphics below:

4.- BMS COMMUNICATIONS
Since the unstoppable growing trend of Building Automation, driven by the powerful ever evolving connectivity, controller climatic 40
offers the possibility to communicate to Building Management Systems (BMS) via Modbus protocol.
Modbus standard interface is integrated in the control, so you don’t need any sort of gateway, router, etc.
In order you to connect to RS485 serial line we provide, as optional, TTL-RS485 converter for Ecolean and Aircube units.
Aircoolair units don’t need the converter (it’s integrated) but they need ambient or duct remote sensor option.
5.- TIME BANDS PROGRAM (Ecolean)
Controller Climatic 40 allows to program 2 time bands every day, each one with a different set point.
Settings parameters are explained in the following table:
For further information, please see BMS communiction manual.
EXAMPLE (Cooling):
WARNING
Set internal clock before programming time bands (t01=hour, t02=minutes, t03=day, t04=month, t05=year).
To deactivate time bands program, set start time = end time.

6.- LOW NOISE
This function is available only in the following units:

AIRCOOLAIR ANCM + kit -15ºC y ANHM 22E-86D
AIRCUBE KSCM + kit -15ºC y KSHM 22E-86D
This function moves the condensing pressure set point so as to lower the fan speed and consequently reduce noise (specically at
night). If low noise is active in 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.
Furthermore set the following parameters:
Low noise cooling mode shift is illustrated in the following picture.

COMPRESSOR- WATER PUMP (ECOLEAN)
In both heating and cooling modes, the compressors start 150 seconds after the water pump has started in order to stabilize the
water system.
In addition to that, the water pump stops 4 minutes later than last compressor has stopped, in order to take advantage of the remai-
ning thermal energy in the exchanger.

The defrosting process is activated during heating mode in heat pump units, when the outside temperature is low and the outdoor
coil could become 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, consequently the pressure switch is disabled in this mode.
Defrost cycle is illustrated in the following picture.

ADVANCED FUNCTIONS
WATER PUMP- WATER FLOW SWITCH (ECOLEAN)
Water ow switch assures that water pump does not work when there is no water ow. There is a by-pass during the rst 150
seconds of water pump operation because of water ow switch signal. When the alarm has been activated, water pump is stopped.
Water pump starts again every 90 seconds during a time of 150 seconds, to try to reset the alarm. This procedure is repeated 5
times and after that the pump remains stopped until the alarm does not reset manually.

If the pressure does not reach the 20 bars before 8 minutes from the beginning of defrost cycle, the cycle nishes because of maxi-
mum time and in the display appears “dF1” or “dF2” (according to the circuit).
Time between two defrost cycles for the same circuit: 40 minutes. Time between two defrost cycles of both circuits: 10 minutes.

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

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

NOTA
At start-up the fan works at maximum speed for 20 seconds, so
as to overcome the mechanical inertia of the motor.
The same time is observed in reference to the start of the com-
pressor (irrespective of the condensing temperature) in order to
bring forward the sudden increase in pressure (which does not
necessarily correspond to a likewise rapid increase in tempera-
ture in the area where the probe is located) and consequently
to improve control.

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 drawing below:
HEATING MODE (only heat pump units). The low/high fan
speed is managed according to the ambient thermostat. See the

ADVANCED FUNCTIONS
11.- FREE COOLING
This option takes advantage of external conditions for cooling mode.
The freecooling is enabled when outdoor temperature is 1ºC lower than indoor temperature and when the rst one is:
- < 10ºC, deactivate compressors and open completely air intake gate in order to refresh only by outdoor air (enough in this conditions).
- >10ºC, open air intake gate and delay compressors, which turn on only in the case outdoor fresh air would not be sufcient to
achieve comfort setpoint.
Picture below shows freecooling regulation.
With free cooling
Open air damper.
Close air damper.
Without free cooling
Stop air damper.

OPTION
To get a constant air renovation, the damper can be partially open, according to the following values.
