OPERATING CONTROLS

The following controls are located on the front of the control box door, under front panel. To obtain access to operating controls, remove the unit front panel as shown on page 2. See Figure 18.

■FAN CYCLE SWITCH — (Typically available at wall thermostat on RC or RP units.) This allows the fan to operate in two modes:

CON (Continuous) — This setting allows the fan to run continuously, circulating air even when the tem- perature setting has been satisfied. This switch helps to maintain the room temperature closer to the ther- mostat setting. Use this switch position when maxi- mum comfort is desired. This is the factory default setting.

CYC (Cycle) — This setting allows the fan to cycle on and off with the compressor during heating or cooling. The fan stops when the temperature setting is satis- fied. This results in longer unit off-time and wider variations in room temperature and humidity.

■OUTDOOR THERMOSTAT (52CQ and 52PQ HEAT PUMP UNITS ONLY) — If the setscrew is left at the factory setting (in the heat pump position), the unit will operate in the reverse cycle heating mode. See Figure 18. When the temperature of the outdoor coil reaches 20 F (approximately 35 F outdoor air tempera- ture), the compressor will shut down as unit is no longer capable of adequate heating in heat pump mode. The electric heater then becomes the primary heating source. The electric heater remains on until the temperature of the outdoor coil reaches 40 F; then the electric heater is shut off and the compressor is energized. Once the compressor is energized, the heat pump again becomes the primary heating source.

To set unit to operate in electric heat mode only, turn the setscrew to the electric heat position. See Figure 18.

IMPORTANT: If setscrew on standard heat pump unit is set to electric heat mode operation, the com- pressor is disabled for both heating and cooling operations. If setscrew on heat pump unit with wall thermostat control is set to electric heat mode operation, the compressor will be disabled only for heating operation.

OPERATING MODES (See Figures 19

and 20.)

■OUTSIDE AIR — To bring outside air into occupied space, turn the vent handle to the full open position. See Figure 17.

■OFF — The OFF mode terminates unit operation.

■FAN— The FAN mode will circulate air in the space at high speed and at high or low speed for cooling only models.

■HIGH HEAT OR HIGH COOL — Select mode and rotate temperature knob to desired comfort level. This function provides maximum heating or cooling, and is recommended to raise or lower the room temperature quickly.

■LOW HEAT OR LOW COOL — Select mode and rotate temperature knob to desired comfort level. This function provides minimum heating or cooling with maximum dehumidification and quietest operation.

■FAN SPEED CONTROL FOR 52P AND 52C WALL THERMOSTAT MODELS — For maximum comfort, fan speed is user selectable at the unit. See Figure 20.
