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 "Commissioning"), room frost protection will be
automatically disabled for 12 hours after the first power-on.
If the screed dryout still needs to be performed after the first 12 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.
NOTICE
For the underfloor heating screed dryout to be able to start, make sure the following
settings are met:
▪
[4‑00]=1
▪
[C‑02]=0
▪
[D‑01]=0
▪
[4‑08]=0
▪
[4‑01]≠1
