DUAL CLIMA R
Connecting a 2-wire Heating/Cooling switching thermostat
This type of thermostat allows the user to select the desired temperature and operating periods for
chrono-thermostats. Unlike the 3-wire heating/cooling switching thermostat, the 2-wire thermostat
does not allow selection of the operating mode (Heating /Cooling ) only on the thermostat itself.
It will be necessary to select the operating mode on both the thermostat and the heat pump. For this
room thermostat management to operate correctly, the heat pump and the thermostat must be
configured
solely for
the Heating or Cooling operating mode
As indicated in the figure, if the thermostat signal requires it, the electronic control of the heat pump
will start to operate in "Manual" mode, that is, the Heating/Cooling operating modes must be selected
manually from the remote control.
OFF (Stand By)

Terminals
C
,
H
and
COM
are supplied from the factory with a jumper connected to each of them.
Therefore, to install this type of thermostat, it will be necessary to remove
the two
jumpers and
connect the thermostat as described in the following figure, with a bridge being required between
inputs
C
and
H
:
IMPORTANT: Before carrying out any work on the electrical installation of the heat pump,
always ensure it is disconnected from the mains.
