the
used
external
room
thermostat
or
heat
pump
convector can only send a

Remote controller of the heat pump convectors
▪ The heat pump convectors are directly connected to the indoor
unit.
▪ The desired room temperature is set via the remote controller of
the heat pump convectors.
▪ The space heating demand signal is sent to one digital input on
the indoor unit (X2M/1 and X2M/4).
▪ The space operation mode is sent to the heat pump convectors by
one digital output on the indoor unit (X2M/33 and X2M/34).
INFORMATION
When using multiple heat pump convectors, make sure
each one receives the infrared signal from the remote
controller of the heat pump convectors.
