NOTICE
The installer is responsible for:
▪
contacting the screed manufacturer for the maximum allowed water
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.
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
