Underfloor screed dryout function
The underfloor screed dryout function is started (if
necessary).
8.2.1

To check the minimum flow rate

1 Check the hydraulic configuration to find out which
space heating loops can be closed by mechanical,
electronic, or other valves.
2 Close all space heating loops that can be closed.
3 Start the pump test run (see
actuator test run" [ 4 38]).
(a)
4 Read out the flow rate and modify the bypass valve
setting to reach the minimum required flow rate + 2 l/
min.
(a)
During pump test run, the unit can operate below the minimum
required flow rate.
If operation is...
Cooling
Heating/defrost
Domestic hot water production

To perform an air purge

Conditions: Make sure all operation is disabled. Go to [C]:
Operation and turn off Space

Air purging heat emitters or collectors
We recommend to purge air with the unit's air purge function (see
above). However, if you purge air from the heat emitters or
collectors, mind the following:
WARNING
Air purging heat emitters or collectors. Before you
purge air from heat emitters or collectors, check if
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.

operation, the unit may NOT operate or may NOT deliver
the required capacity.
To monitor leaving water and tank temperatures
During test run, 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 temperatures:
1 In the menu, go to Sensors.
2 Select the temperature information.
