The basic connection of the 30AWH__H heat pump can be controlled by binary signals. The heat pump is equipped with a compressor with the inverter technology, which provides both heating and cooling and is produced in several performance versions. For detailed information on the assembly and electrical connection, see the heat pump instruction manual.

The following figure shows an example of possible connection to the C-HM-0308M module (heat pump control) and measuring the heat pump current by the ED11.M electricity meter.

Notes:

  1. The binary input of the heat pump must be controlled by contacts with at least 25 mA 12 V switching current.

  2. Terminals of the heat pump: 3: Off/ON, 6: cooling/heating, 7:Normal/Economic.

  3. The value of the 230 V power supply input protection depends on the type of the heat pump – see the heat pump documentation.
