temperature, to avoid cracking the screed,
▪
programming the underfloor heating screed dryout schedule according to the
initial heating instructions of the screed manufacturer,
▪
checking the proper functioning of the setup on a regular basis,
▪
performing the correct program complying with the type of the used screed.

supply the leaving water without heat pump operation.
