5.5 Connecting the room thermostat (“AUTO” mode)
The Fusion Hybrid Oil module is prepared for the connection of up to 2 room programmable
thermostats or room thermostats (see
“Connection Diagram”
), which will activate or stop the heating
and/or cooling service of the heating/air-conditioning installation, turning off the heat pump and the
supporting module when the desired temperature is reached in the home and turning it on when it
comes down again.
Connecting terminals
33 and 35 , will activate and deactivate the Cooling mode, and connecting
terminals 33 and 34 of the terminal strip (see
“Electrical Diagram”
) will activate and deactivate the
Heating mode, so that the operating modes of the heating/air-conditioning system will be remotely
and automatically managed (
“AUTO” mode), from the place where the installed room thermostats are
located.
Terminals
33, 34 and 35 are supplied from the factory with a jumper wire connected to each of them,
so, irrespective of the configuration of thermostats to be installed, it will be necessary to remove
both
jumper wires before connecting the room thermostats.
Depending on the types of thermostats used or their combination, up to 3 types of room thermostat
configurations can be installed. The following sections describe in detail the operation and installation
of each of these configurations.
DANGER: When handling the electrical installation, make sure that both the module and
the Dual Clima heat pump are disconnected from the mains.
Connecting a switched thermostat for Heating/Cooling with 3 wires (“AUTO” mode)
In addition to selecting the desired temperature and periods of operation, this type of thermostat,
if it is of the programmable thermostat type, offers users the possibility of selecting the mode of
operation (Heating /Cooling ) in the thermostat itself.
For its operation, this type of thermostat has 3 communication wires: one for the activation signal
of the Heating mode, one for the activation signal of the Cooling mode, and one for the common
signal. Depending on the status of each of the signals, the
Dual Clima heat pump will manage the
Heating/Cooling operating modes as follows:
