OPERATING CONTROLS

The following controls are located on the front of the chassis. To obtain access to operating controls, remove the unit front panel as shown on page 2. See Figure 14.

IMPORTANT: When unit is first started, high humidity conditions can cause condensation to form on discharge grille. Keep doors and windows closed. Room humidity decreases and moisture evaporates.

■FAN CYCLE SWITCH — (Not available 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 HEAT PUMP UNITS ONLY) — If the setscrew is left at the factory setting (in the heat pump position), the unit will oper- ate in the reverse cycle heating mode. When the tem- perature of the outdoor coil reaches 20° F (approxi- mately 35° F outdoor air temperature), the compressor will shut down. The electric heater remains on until the temperature of the outdoor coil reaches 35° F

(approximately 45° F outdoor air temperature); then the electric heater is shut off and the compressor is energized.

IMPORTANT: Once in electric heat mode, the com- pressor is disabled for heating and cooling.

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

OPERATING MODES (See Figures 15

and 16.)

■OUTSIDE AIR — To bring outside air into occupied space, turn the vent handle to the full open position. See Figure 13.

■OFF — The OFF mode terminates unit operation.

■FAN— The FAN mode will circulate air in the space at high speed.

■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.

NOTE: 52C wall thermostat units have a blank plate. See Figure 14.
