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.
3.- DYNAMIC SET POINT
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:

ADVANCED FUNCTIONS
4.- BMS COMMUNICATIONS
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.
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.
The setting parameters are explained in the following table:**
For further information, please see BMS communication 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 programme, set start time = end time.

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.
ADVANCED FUNCTIONS
WATER PUMP- WATER FLOW SWITCH (ECOLEAN / HYDROLEAN)
The water flow switch ensures that the water pump does not work when there is no water flow. At first, there is a by-pass during the first
150 seconds of water pump operation which operates according to the water flow 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.

If the pressure does not reach 30/35 bars within 8 minutes from the start of the defrost cycle, the cycle finishes 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 tempe-
ratures 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.
FAN SPEED
CONDENSER PRESSURE (bar)
NOTE
At start-up the fan works at maximum speed for 20 seconds, so
as to overcome the mechanical inertia of the motor.
1.2.- PROPORTIONAL CONTROL BASED ON PRESSURE TEMPERATURE
Models: ECOLEAN: . . . . . . EAC 251-812 SM
AIRCOOLAIR: . . ANCM 22E-86D
AIRCUBE:. . . . . . . KSCM 22E-86D
In this case too, it is a proportional fan speed control, which varies the voltage supplied to the fan.

CONDENSER TEMPE-
RATURE (ºC)
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 with regard to compressor start-up
(irrespective of the condensing temperature) in order to improve
temperatures probes reading.
1.3.- ON/OFF CONTROL BASED ON PRESSURE
Models: ECOLEAN: EAR* 1003-1804 SM
AIRCOOLAIR: ANHM* 112D-152D
AIRCUBE: KSHM* 112D-214D
ON/OFF, through the control and change between high and low fan speed through pressure switches.
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:

NOTE*: In these same models, but in cooling only version, the fan speed management is the same, apart from that, the ON/OFF signal
is provide by a pressure switch instead of the control.

is managed according to the outdoor temperature thermostat.

11.- FREE COOLING (AIRCOOLAIR)
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 (sufficient under
these conditions).
• >10ºC, the air intake gate opens and delays the compressors, which turn on only if there would be insufficient outdoor fresh air
to achieve the comfort setpoint.
The illustration below shows freecooling regulation.
With free cooling
Open air damper.
Close air damper.
Without freecooling

OPTION
To get a constant air renewal, when freecoling conditions are satisfied, the damper is mantained opened partially (20%), according to the
following values.
