9.4.5
Underfloor heating screed dryout
This function is used for drying out the screed of an underfloor
heating system very slowly during the construction of a house. It
allows the installer to program and execute this program.
Conditions:
Make sure all operation is disabled. Go to the
Operation menu and turn off Room, Space heating/cooling and Tank
operation.
This function can be executed without finishing the outdoor
installation. In this case, the backup heater will perform the screed
dryout and supply the leaving water without heat pump operation.
When no outdoor unit is installed yet, then connect the main power
supply cable to the indoor unit via X2M/30 and X2M/31. See
"7.6.8 To connect the main power supply" on page 33
.
INFORMATION
▪ If Emergency is set to Manual ([A.6.C]=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
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 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.
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
The installer can program up to 20 steps. For each step he needs to
enter:
1
the duration in hours, up to 72 hours,
2
the desired leaving water temperature.
