A INV Comp. Inverter Compressor
The inverter compressor’s speed is controlled based on coil pressures monitored by the
unit's pressure transducer (PT)
BT5
Compressor discharge
temperature sensor
Used for compressor discharge temperature protection and EEV control in heating mode.
C HPS High Pressure Switch
— High Pressure Switch opens at P > 580 PSIG, the compressor and outdoor fan
stop.
— High Pressure Switch closes at P < 435 PSIG, the compressor and outdoor fan
restart.
D RV Reversing Valve Used to switch mode between cooling and heating.
E Fan Outdoor Fan Used for heat exchange
F T3 Outdoor Coil temperature sensor
— Used for discharge temperature protection
— Fan control (cooling mode)
— Defrost control (heating mode)
G T4 Outdoor Ambient Temperature sensor Used for ambient protection and fan control in heating mode, and defrost control.
H EEV Electronic Expansion Valve
Fully open during cooling mode and adjusted during heating mode. Controlled in heating
mode via compressor discharge superheat.
I CV Check Valve Open during cooling and closed during heating.
J PT Pressure Transducer
— Compressor frequency control
— Electronic Expansion Valve (EEV) control (heating mode only)
— High pressure protection (heating mode)
— Low pressure protection (cooling mode)
KTf
Control board heat dissipation
temperature sensor
Used for control board heat dissipation temperature protection.
L Th Compressor Suction temperature sensor Used to monitor suction temperature
M T3L Liquid Line temperature sensor Used to monitor condenser outlet temperature
N PEV Pressure Equalizer Valve Used to balance pressure before compressor starts
O TXV Thermal Expansion Valve Used only in cooling mode to control superheat and protect compressor
P Bi-Flow Filter Drier Bi-Flow Filter Drier Used to remove refrigerant impurities in order to protect compressor
