Components
The indoor console unit functions as an evaporator coil during cooling mode, and as a condensing coil during heat mode.
Condensate is collected by a drain pan below the coil and condensate is drained directly to the outdoor or to a secondary
condensate pump via the provided condensate drain line
Console units may be operated with either a wired remote control or the wireless remote control provided with the unit.

Display
The indoor unit display communicates system mode, but
does not display temperatures or diagnostic codes. This
information is indicated on the wired or wireless control.
When servicing a diagnostic error always refer to the
outdoor unit code.

Ambient Sensor
The Ambient Temperature Sensor senses room
temperature. This sensor provides room temperature
information to the ECU for calculation of inverter capacity
and temperature control.
WiFi Module
Coil Sensor
The Coil Temperature Sensor senses indoor coil
temperature in the cooling mode and in the heating
mode. This sensor is used for Anti Freezing and Anti
Cold Blow cycles. The sensor also provides critical
temperature information to the ECU that may be used in
frequency adjustments.
Flare Connections
Condensate Drain
Lower Damper Motor
Upper Louver Motor
The louver motor is a stepper type motor that moves
the louver left/right. The motor is controlled by a pulsed
voltage that cannot be measured. If the louver does not
move when it should, check for a bind in the louvers.
Blower Fan (behind coil)
Blower Motor (behind coil)
The indoor unit features a multi-speed blower motor
that will change speed to match the capacity demand
from the outdoor unit. The blower motor is controlled
by both the remote control and by commands from the
outdoor unit ECU
