Control unit wiring

Figure 21 shows the control unit wired to a wall display unit and the HVAC system. Wire colors are typical thermostat wiring colors. The fuse is a mini ATO 2 amp.

Note: For heat pump HVAC systems, the orange wire (O) is the changeover valve.

HVAC system transformer

Most central HVAC systems have a common heating and cooling transformer. This is the factory default setting for jumper JP1. In some cases you may have separate heating and cooling systems, each with their own transformer. In that case, cut jumper JP1 and wire the heating transformer red wire to the RH terminal and the cooling system transformer red wire to the RC terminal. Wire the cooling system’s 24 VAC Com to the control unit’s 24 VAC Com terminal. Do not connect the heating system’s common wire to the control unit.
