11.4.3 Operation test run
Purpose
Perform test runs on the unit and monitor the leaving water and tank
temperatures to check if the unit is working correctly. The following test runs
should be made:
▪
Heating
▪
Cooling (if applicable)
▪
Tank
NOTICE
Before starting a space heating test run, make sure all emitters are open.
During
the space heating test run, the unit measures the time to achieve a certain
temperature increase in the system. This timeframe is then used in the logic to
activate the backup heater (see
191]). When (part of) the emitters
are closed, this might result in more frequent backup heater operation.
INFORMATION
The test run only applies to the additional temperature zone.
INFORMATION
When performing a space heating test run, the backup heater is NOT checked. To
check backup heater operation, perform the
Backup heater 1
and
Backup
heater 2
test (see
222]).
To perform an operation test run
Conditions:
Make sure all operation is disabled. Go to [C]:
Operation
and turn off
