WARNING
Air purging heat emitters or collectors. Before you
purge air from heat emitters or collectors, check if or
is displayed on the home screen of the user interface.
▪ If not, you can purge air immediately.
▪ If yes, make sure that the room where you want to
purge air is sufficiently ventilated. Reason: Refrigerant
might leak into the water circuit, and subsequently into
the room when you purge air from the heat emitters or
collectors.

INFORMATION
When starting up the system in a cold climate, and NO
backup heater kit was installed, 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.
If the installation of the unit has been done correctly, the unit will
start up during test operation in the selected operation mode. During
test mode, the correct operation of the unit can be checked by
monitoring its leaving water temperature (heating/cooling mode) and
tank temperature (domestic hot water mode).
To monitor the temperature:
1 Go to Sensors.
2 Select the temperature information.
6.2.4 To perform an actuator test run
Conditions: Make sure all operation is disabled. Go to the
Operation menu and turn off Room, Space heating/cooling and Tank
operation.
Purpose of the actuator test run is to confirm the operation of the
different actuators (e.g., when you select Pump, a test run of the
pump will start).
1 Set the user permission level to Installer. See "To
change the user permission level"on page14.
—
2 Go to [A.2]: Commissioning > Actuator test run.

To stop the test run manually: —
1 Go to Stop test run.
2 Select OK to confirm.
Possible actuator test runs
▪ Booster heater test
▪ Backup heater 1 test (if applicable)
▪ Backup heater 2 test (if applicable)
▪ Pump test
INFORMATION
Make sure that all air is purged before executing the test
run. Also avoid disturbances in the water circuit during the
test run.
▪ Shut off valve test
▪ Diverter valve test
▪ Bivalent signal test
▪ Alarm output test
▪ C/H signal test

6.2.5 To perform an underfloor heating screed
dryout
Conditions: Make sure all operation is disabled. Go to the
Operation menu and turn off Room, Space heating/cooling and Tank

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.
