NOTICE
The energy measurement for heating or cooling can be conducted without an addi-
tional energy meter. The measurement can be used for the internal distribution of
heating and cooling costs or for system monitoring. As the heating and cooling
quantity measurement is not calibrated, it cannot be used as the basis for billing.
NOTICE
For constant recording of the heating/cooling quantity without interrupting data re-
cording, the pump must only be switched on/off via the DI input with EXT. OFF.
There is no data recording when the mains voltage is switched off.
