"9.2 Connections to the outdoor
▪ The heat pump convectors are directly connected to the outdoor unit – or to the
external backup heater kit, if there is one.
▪ 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 controller of the heat pump
convectors. There are different controllers and setups possible for the heat pump
convectors. For more information, see:
- The installation manual of the heat pump convectors
- The installation manual of the heat pump convector options
- The addendum book for optional equipment
▪ The space heating/cooling demand signal is sent to one digital input on the
outdoor unit (X2M/35 and X2M/30).

the outdoor unit to:
- The heat pump convectors
- The shut-off valve
