Discharge Temperature Sensor

Defrost Temperature Sensor

TheDefrost Temperature Sensor is a negative coefficientthermistor that will change resistance in response to outdoorcoil temperature changes. TheMain Control Boardmonitorsthe temperature of the outdoor coil to determinewhen thesystem is needing to perform a defrost cycle. The sensor alsomonitors outdoor coil temperature during defrost cycles todetermine termination conditions.

This sensor connects to theMain Control Board at PLUGCN-19.

TheDischarge Temperature Sensor is a Negative Coefficientthermistor that senses the temperature of the compressorhot gas. TheMain Control Boardmonitors the temperature ofthe compressor hot gas andwill make inverter speed changesin response to input from this device.


Outdoor Ambient Temperature Sensor

Suction Line Temperature Sensor

The Suction Line Temperature Sensor is a negativecoefficient thermistor that senses the temperature ofthe suction line. TheMain Control Boardmonitors thetemperature of the suction line to determine EEV orifice sizein an attempt tomaintain proper operating superheat.


TheOutdoor Ambient Temperature Sensor is a negativecoefficient thermistor that will change resistance in responseto outdoor air temperature changes. TheMain Control Boardmonitors the temperature of the outdoor air to determineoutdoor fan speed requirements and inverter speed. Thesensor also plays a role in calculation of required defrostconditions.



ENG

LIS

H4-Way Valve

Electronic Expansion Valve

Themetering device is an electronic expansion valve typeEEV.EEV.EEV The valve consists of an electrical operator and a valvebodywith internal variable size orifice.When operating,theMain Control Boardwill send pulses of voltage to theelectrical operator. The operator will thenmagneticallymovethe position of themetering orifice pin to vary its size.

Themetering device position is determined by input froma Suction Line Temperature Sensor located in the outdoorunit. The EEVwill change the internal orifice size tomaintain asuperheat level of around 10°F.

The 4-Way Valve redirects the flowof refrigerant in the pipingcircuit to allow the system to swap the functions of the indoorand outdoor coils. When de-energized in COOLMODE, thevalve will direct the refrigerant hot gas to the outdoor coil.When energized in HEATMODE, the valve will direct the hotgas to the indoor coil.

The valve flow direction capability is controlled by anelectrical solenoid.When energized by 240 Volts, line voltage,the solenoid will magneticallymove an internal slide withinthe 4-Way Valve to change the direction of refrigerant flow.

The 4-Way Valve is electrically connected to theMain ControlBoard at PLUGCN-10.

Accumulator

The Accumulator is located in the suction line circuit at theentrance to the compressor. The accumulator helps preventliquid refrigerant from entering the compressor during runoperation.

Refrigerant Filters

The systemhas debris catching filters that protect internalsystem components from contaminants in the refrigerant.The filter is a permanent part that is not typically replaced.

During COOLMODEoperation, the valvemeters lowpressure refrigerant to the indoor coil. During HEATMODEoperation, the valvemeters low pressure refrigerant to theoutdoor coil.

*Indoor fan control manual control: You can choose high, medium, low and automatic speed control. Automatic: When Tr<Ts, high speed. When Ts≤Tr≤Ts+2 , medium speed. When Tr> Ts+2 , low speed. When the airflow speed has no delay from the high to low switching, the speed should be delayed for 3 minutes (remain at high speed for 3 minutes.) before the next switch. *Airgate location control: the location for the airgate can be set according to your needs. Coldair proof operation 1. The indoor operation within 4 minutes after the start up is as the following diagram, the air speed can be raised only after the speed has reached a certain level.

2. 4 minutes after the start up of the indoor fan, the light airflow and the low airflow will be turned to the set speed airflow. 3. In the cold air proof operation, the fan won’t stop after the start up. 4. During the cold air proof operation, the indoor system will continuously send ‘indoor high speed’ signals to the outdoor system. * Residue heat sending. The indoor fan will send the residue heat at a low speed for 12 seconds. If other conditions are satisified, when the compressor stops, the indoor system will operate at a light speed. The indoor fan will stop when the coil temperature is below the ‘heat start temp 4’. * Defrosting. When the system receives the defrosting signal from outdoors, the indoor fan will stop and the indoor temperature display won’t change. At the time, any indoor coil malfunctions will be neglected. When the outdoor defrosting finishes, the coil malfunction will still be neglected until the compressor has been started up for 30 seconds. The indoor temperature display will not change and the system operates at the cold air proof mode. * Automatic heating temperature compensation: when the system enters the heating mode, the temperature compensation (4) will be added. When the status is switched off, the compensation will be erased.
