HKK PCB
There are 3 connection groups on the HKK PCB:
A1 (Only for one HC)
A2 (For HC or TWE)
A3 (For HC, TWE, SOL or internal electrostatic precipitator)
The connections of a connection group belong
together. The appliances for a specific heating circuit
must be connected to the connections of a group.
For a detailed overview of connection options, see
ZPK 2.03 PCB in chapter "Connection and wiring dia-
