▪ Efficiency. Although the external room thermostat only sends ON/OFF signals, it
is specifically designed for the heatpump system.
▪ Comfort. In case of underfloor heating, the wireless external room thermostat
prevents condensation on the floor during cooling operation by measuring the
room humidity.

▪ For more information about connecting the electrical wiring to the unit, see
"8.2 Overview of electrical connections for external and internal
actuators"[480].
▪ 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/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.
