The shut-off valves are properly installed and fully open.
The stop valves (gas and liquid) on the outdoor unit are fully open.
The air purge valve is open (at least 2 turns).
The pressure relief valve purges water when opened. Clean water MUST come out.
The minimum water volume is guaranteed in all conditions. See "To check the water
volume and flow rate" in "8.5 Preparing water piping" [ 4 75].
The domestic hot water tank is filled completely.
11.4 Checklist during commissioning
The minimum flow rate during backup heater/defrost operation is guaranteed in all
conditions. See "To check the water volume and flow rate" in "8.5 Preparing water

11.4.1 To check the minimum flow rate
Mandatory procedure for the additional zone
1 Confirm according to the hydraulic configuration which space heating loops
can be closed due to mechanical, electronic, or other valves.
2 Close all space heating loops that can be closed (see previous step).
3 Start the pump test run operation (see "11.4.4 To perform an actuator test
run" [

4 Go to [6.1.8]: > Information > Sensor information > Flow rate to
check the flow rate. During pump test run operation, the unit can operate
below this minimum required flow rate that is needed during defrost/backup
heater operation.
Recommended procedure for the main zone
5 Confirm according to the hydraulic configuration which space heating loops
can be closed due to mechanical, electronic, or other valves.
6 Close all space heating loops that can be closed (see previous step).
7 Create a thermo request on the main zone only.
8 Wait 1 minute until the unit is stabilized.
9 If the additional pump is still assisting (the green LED on the right hand sided
pump is ON), increase the flow until the additional pump is NOT assisting
anymore (LED is OFF).
