When starting up the system in a cold climate, it may be
required to start up with a small water volume. To do this,
gradually open the heat emitters. As a result, the water
temperature will gradually rise. Monitor the inlet water
temperature ([6.1.6] in the menu structure) and make sure
it does NOT drop below 15°C.

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.

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
▪ [D‑01]=0
▪ [4‑08]=0
▪ [4‑01]≠1
