10.4 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 "7.2 Preparing water
piping" [ 4 53].
To perform an air purge .
To perform a test run .
To perform an actuator test run .
Underfloor screed dryout function
The underfloor screed dryout function is started (if necessary).
10.4.1 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 "10.4.4 To perform an actuator test
run" [
4
143]).
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).
10 Go to [6.1.8]: > Information > Sensor information > Flow rate to
check the flow rate.
10.4.2 Air purge function
Purpose
When commissioning and installing the unit, it is very important to remove all air in
the water circuit. When the air purge function is running, the pump operates
without actual operation of the unit and the removal of air in the water circuit will
start.
NOTICE
Before starting the air purge, open the safety valve and check if the circuit is
sufficiently filled with water. Only if water escapes the valve after opening it, you can
start the air purge procedure.
