Underfloor heating screed dryout
This function will be used to dry-out the screed of an underfloor
heating very slowly during the construction of a house. It allows the
installer to program and execute this program.
Make sure that the leaving water temperature home page, room
temperature home page, and domestic hot water home page are

INFORMATION
▪ If Emergency is set to Manual ([A.5.1.2]=0), and the
unit is triggered to start emergency operation, the user
interface will ask confirmation before starting. The
underfloor heating screed dryout function is active even
if the user does NOT confirm emergency operation.
▪ During underfloor heating screed dryout, pump speed
limitation [9‑0D] is NOT applicable.
NOTICE
The installer is responsible for:
▪ contacting the screed manufacturer for the initial
heating instructions to avoid cracking the screed,
▪ programming the underfloor heating screed dryout
schedule according to the above instruction of the
screed manufacturer,
▪ checking the proper functioning of the setup on a
regular basis,
▪ selecting the correct program complying with the type
of the used screed of the floor.
NOTICE
Room frost protection is default disabled ([2‑06]=0). Do
NOT enable this function until the underfloor screed dryout
function is completed successfully. Ignoring this notice can
result in cracking of the screed.
