▪ The heat pump convectors are directly connected to the indoor unit.
▪ A shut-off valve (field supply) is installed before the underfloor heating to
prevent condensation on the floor during cooling operation.
▪ 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).
