In split- or MONO-block heat pumps, the connectors for the adapter cable are in
different places on the main PCB. On the main PCB, the connectors are labelled with
"CN-REMOTE" for a split-heat pump and "CN-REMOTE2" for a MONO-block heat
pump. When replacing the cables, the power to the heat pump and the controller must
be switched off.
When the basic parameters in the HPM have been adjusted, the other end of the
adapter cable must be connected to the BUS interface of the HPM. The heat pump
will emit a beep if the connection was successful.
As an accessory there are 2 different adapter cables available for the connection
between HPM and the heat pump. They have been developed especially for the
communication with Panasonic split- and MONO-block heat pumps and only work in
the right combination.

Cascade via contact activation
Controlling the heat pump(s) via a contact signal permits control of up to 3 heat
pumps in a cascade. This requires using the right external connections for the heat
pump. Depending on the system in question, either terminal 9/12 or terminal 17/18
must be used.
