Your contractor has connected an external heat gener-
ator as a second heat source to your heat pump.
Emissions test mode for testing flue gas from your
external heat generator must only be activated by your
flue gas inspector during the annual inspection.
Have the emissions test on the external heat generator
carried out during the heating season if possible.
Emissions test mode must be turned on separately,
first on the heat pump programming unit and then
on the external heat generator.
As soon as emissions test mode is turned on for the
heat pump, the heat pump shuts down. The
hydraulic components of the indoor unit are connec-
ted up so that the entire thermal energy from the
external heat source is transferred to the heating/
cooling circuits or to the separate buffer cylinder if
installed.
Ensure, therefore, that there is adequate heat trans-
fer in the heating/cooling circuits, e.g. by opening
thermostatic valves.
Note
The flue gas inspector can activate emissions test
mode on the heat pump programming unit even if the
control panel is locked.
Switching on emissions test mode
Tap the following buttons:
1. On the heat pump programming unit:
2. "Test mode"
3.
4. On the external heat generator:
Switch on emissions test mode on the external
heat generator.
Follow the operating information for the external
heat generator.
