4.2 Unit PCBs
4.2.1 Types
Heat pump has two types of PCBs – one for the hydraulic system and the other for the refrigerant
system. All models share the same hydraulic system PCB. The number of PCBs of each model is
for reference to Table 4-2.1 below.

The locations of each PCB in the unit electric control boxes are shown in Figures 4-2.1, 4-2.2,
4-2.3, 4-2.4, 4-2.5. For 8/10/12kw, Inverter module and refrigerant system module constitute an
integrated PCB which is called drive PCB. For 14/16kw, Drive PCB and refrigerant system PCB are
separate.
