Heating power meter (water heater) |
Energy insight monitors how much power the water heater is adding to the airflow to heat it up.
The formula for added power calculation:
Where:
Heater valve leakage monitors ΔT then output of the heater's sequence is 0% (no need for active heating). The increase of the ΔT by more than 2 oC indicates the leak of the heater valve and triggers alarm 1085 Leakage heater valve.

Heater valve leakage delta-T |
[2.0] oC |
Alarm 1085 Leakage heater valve is triggered if the heater is adding more than +2 oC to the passing air then heating is not required (indicating valve leakage) |
