35 DUAL CLIMA R
Two room thermostat installation
In this type of configuration 2 simple room thermostats will be connected, one connected to C and
COM inputs (cooling room thermostat CRT ) and the other connected to H and COM inputs (heating
room thermostat HRT ). Each of them will manage a different operation mode, so every thermostat will
have to be of a type compatible with the functioning mode for which it has been installed. The room
thermostat connected to cooling input (
CRT ) has to be activated (close signal) when room temperature
is higher than the one desired (setpoint temperature), and in the same way, the room thermostat
connected to heating input (
HRT ) has to be activated (close signal) when room temperature is lower
than the one desired (setpoint temperature).
The DUAL CLIMA R heat pump will activate the Heating/Cooling modes depending on the signal
received from each room thermostat in the following way:
Heating mode Cooling mode
OFF (Stand By)
(temp. reached)
Manual mode
As it is described above, in case of adjusting the desired temperatures of the room thermostats in such
a way that both are activated simultaneously, the electronic controller of the heat pump will switch to
"Manual" operating mode, that is, the Heating/Cooling modes will have to be activate and deactivate
in the mainboard of the heat pump manually. To avoid this situation it will be essential
to ensure of
adjusting correctly the desired temperatures of each one in such a way that they do not
cross, preventing both thermostats from activating simultaneously.
The C , H and COM terminals are supplied from the factory with a jumper between each of them, so it
will be necessary to remove both jumpers before connecting the room thermostats, as it is described
in the following diagram:

IMPORTANT: Before carrying out any work on the electrical installation of the heat pump,
always ensure it is disconnected from the mains.
