Terminal Block

The outdoor unit is powered by 208/230 Volt Single Phase
electricity connected at the Outdoor Unit Terminal Block.
Terminals 1 and 2 on the outdoor unit terminal connect
this voltage to the system. The number 3 terminal is a
communication terminal that connects wiring between the
indoor and outdoor units. An earth ground source terminal
connects the outdoor unit to the line voltage power source.
Condensate safety switches should break wire 1.
The indoor unit is also powered by the same electrical supply
as the outdoor unit. #14 AWG wire is connected to the wiring
terminal block at the outdoor unit and is run to the indoor unit
wire terminal block.
When installing the field supplied wiring, make certain the
wire gauge is correct. There should not be any electrical
wiring splices between the indoor unit and outdoor unit
wire. Wire #3 is used to carry communication data between
the indoor and outdoor units. A wiring splice where wires
are twisted in a wire nut may cause deformation of the
communication of the data signal. If communication is lost
between the indoor and outdoor units, an ERROR CODE E7
will occur.
Power Factor Reactor
The Reactor is an inductive filter that will aid in correction of
electrical power factor influence of inverter capacitance. It is
unlikely to ever have an electrical failure of this component.
The Reactor is electrically connected to the Module Board on
terminal connections CN-7 and CN-8.

OUTDOOR UNIT CONTROLS & COMPONENTS

Compressor

The compressor is a three phase DC inverter driven Rotary
type. The compressor is capable of variable speed operation.
The compressor operating frequency will be determined by
the temperature difference between set point and room or
outdoor air temperature. (Cool Mode versus Heat Mode)
The compressor is electrically connected to the Module
Board on terminal connections CN-2, CN-3 and CN-4.
The compressor has an internal temperature overload that
will open if the compressor becomes too hot. Additional
protection of the compressor will be provided by the
Compressor Discharge Temperature Sensor and Suction
Line Temperature Sensor.

Outdoor Fan Motor

The outdoor fan motor is a variable speed motor. The
required motor speed is calculated by the Main Control
Board. The motor is electrically connected to the Main
Control Board via PLUG CN-21.
In COOL MODE operation, the motor will slow down as
outdoor air temperature falls. In HEAT MODE operation, the
motor will increase speed as the outdoor air temperature
falls.
