7.2.5 To perform an underfloor heating screed
dryout
Conditions: Make sure all operation is disabled. Go to [C]:
Operation and turn off Room, Space heating/cooling and Tank
operation.
Conditions:
▪ Make sure all operation is disabled. Go to [C] Operation and turn
off [C.1] Room, [C.2] Space heating/cooling and [C.3] Tank
operation.
▪ Make sure [2.7] and [3.7] Emitter type is set to Underfloor
heating.
1 Set the user permission level to Installer. See "To
change the user permission level"[428].
—
2 Go to [A.4]: Commissioning > UFH screed dryout.
3 Set a dryout program: go to Program and use the
UFH screed dryout programming screen.
4 Select OK to confirm.
Result: The underfloor heating screed dryout starts.
It stops automatically when done.
To stop the test run manually: —
1 Go to Stop UFH screed dryout.
2 Select OK to confirm.
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
Resume after power failure
If power is restored after a power failure, underfloor heating screed
dryout automatically resumes its operation.
7.2.6 To start or stop 10-day brine pump
operation
If a brine buffer vessel is part of the brine circuit, or in case a
horizontal brine loop is used, it may be required to let the brine pump
run continuously for 10 days after the system is commissioned. If 10
day brine pump operation is:
▪ ON: The unit operates as normal, except that the brine pump
operates continuously for 10 days, independent of compressor
status.
▪ OFF: Brine pump operation is linked to compressor status.
Conditions: All other commissioning tasks have been completed
before starting the 10 day brine pump operation. After you have
done this, 10 day brine pump operation can be activated in the
commissioning menu.
1 Set the user permission level to Installer. See "To
change the user permission level"[428].
—
2 Go to [A.6]: Commissioning > 10 day brine pump
operation.
3 Select On to start the 10 day brine pump
operation.
Result: The 10 day brine pump operation
starts.
During the 10 day brine pump operation, the setting will be
displayed as ON in the menu. Once the procedure has been
completed, it will change to OFF automatically.
NOTICE
The 10-day brine pump operation will only start if there are
no errors present on the main menu screen and the timer
will only count down if either an underfloor heating screed
dryout is started, or if Space heating/cooling or Tank
operation is enabled.
