The desired room temperature is set via the remote controller of the heat pump
convectors.
▪
The space heating/cooling demand signal is sent to one digital input on the
indoor unit (X2M/35 and X2M/30).
▪
The space operation mode is sent to the heat pump convectors by one digital
output on the indoor unit (X2M/4 and X2M/3).
INFORMATION
When using multiple heat pump convectors, make sure each one receives the
infrared signal from the remote controller of the heat pump convectors.
