To perform an underfloor heating screed
dryout
Prerequisite: Make sure there is ONLY 1 user interface connected
to your system to perform an underfloor heating screed dryout.
Prerequisite: Make sure that the leaving water temperature home
page, room temperature home page, and domestic hot water home
page are turned OFF.
1 Go to [A.7.2]:
> Installer settings > Commissioning > UFH
screed dryout.
2 Set a dryout program.
3 Select Start dryout and press
4 Select OK and press
.
Result: The underfloor heating screed dryout starts. It stops
automatically when done. To stop it manually, press
and press
.
INFORMATION
In case no outdoor unit is installed, the user interface will
ask if the gas boiler can take over the entire load. After
allowing this, restart the screed dryout program to make
sure all actuators are operating.
NOTICE
To perform an underfloor heating screed dryout, room frost
protection needs to be disabled ([2‑06]=0). By default, it is
enabled ([2‑06]=1). However, due to the "installer-on-site"
mode (see "Checklist before commissioning"), room frost
protection will be automatically disabled for 36 hours after
the first power-on.
If the screed dryout still needs to be performed after the
first 36 hours of power-on, manually disable room frost
protection by setting [2‑06] to "0", and KEEP it disabled
until the screed dryout has finished. Ignoring this notice will
result in cracking of the screed.
