7-3. Address Switches If you are installing more than 1 indoor unit (up to 2) in the same room, it is necessary for you to assign each unit its own address so each can be operated by its own remote control unit. You assign the addresses by matching the switch positions of each indoor unit with the switch positions of its remote control unit.
8. FUNCTION 8-1. Room Temperature Control Room temperature control is obtained by cycling the compressor ON and OFF under control of the room temperature sensor in the remote control unit. The room temperature (and other information) is transmitted every 3 minutes by the remote control unit to the controller in the indoor unit.
Dry operation uses the ability of the cooling cycle to remove moisture from the air, but by running at low level to dehumidify without greatly reducing the room temperature. The air conditioner repeats the cycle of turning ON and OFF automatically as shown in the chart below according to the room temperature.
8-4. Outdoor Fan Speed Control (CL Low ambient fan speed control This function protects the compressor from being damaged due to flowback of the liquid refrigerant to the compressor when the outdoor temperature is very low. When the air temp. thermistor (TH) on the outdoor units detects a change in temperature, the controller on the electrical component box activates to control the fanspeed automatically.

Freeze Prevention”) B. Short When thermistor is shorted, the air conditioner will be in the following conditions as the controller tries to detect extremely high coil temperature. In cooling mode: Function of freeze prevention will not work even when the frost builds up on indoor heat exchanger coil.
10. CHECKING ELECTRICAL COMPONENTS 10-1. Measurement of Insulation Resistance The insulation is in good condition if the resistance exceeds 2MΩ. 10-1-1. Power Supply Wires Clamp the ground wire of the power supply wires with the lead clip of the insulation resistance tester and measure the resistance by placing a probe on either of the power wires.
10-2. Checking Continuity of Fuse on PCB Ass’y Remove the PCB Ass’y from the electrical compo- nent box. Then pull out the fuse from the PCB Ass’y. (Fig. 5) Check for continuity using a multimeter as shown in Fig. 6. 10-3.

This illustration is based on the external appearance of a standard model. NOTE Consequently, the shape may differ from that of the air conditioner which you have selected. This air conditioner consists of an indoor unit and an outdoor unit.
TIMER lamp This section picks up infrared signals from the remote control unit (transmitter). This position is for operating the air conditioner with the wireless remote control unit. Set the selector normally in this position. Switch the selector to the OFF position if you are not going to use the air conditioner for a few days or longer.
