The underfloor heating (UFH) screed dryout function is used for drying out the
screed of an underfloor heating system during the construction of the building.
The UFH screed dryout function can be executed without finishing the outdoor
installation. In this case, the backup heater will perform the screed dryout and
supply the leaving water without heat pump operation.
If the outdoor unit is not yet installed, connect the main power supply cable to the
indoor unit via X2M/30 and X2M/31. See
