Thermostat/Controller Operation - OCEANAIRE OWC QC Series Engineering, Installation And Service Manual

DELUXE ELECTRONIC CONTROLLER
The OWC QC controller is equipped with many features for a more precise level of
cooling and operation. With the addition of a remote sensor, the controller can sense
temperatures in another space or in ductwork. Doing that, you override the temperature
sensing bulb behind the evaporator grille.

humidity within the conditioned space. Every 4 hours, the fan is started, circulating the
air, and the air temperature is recorded by the controller. The cooling cycle is
started for one hour, or until the room temperature drops 2°, which ever comes first.
This cycle repeats every four hours.
FAN SPEED
—The operator can select between AUTO or MANUAL fan speed control.
Pressing the FAN SPEED button will switch speed from AUTO to MANUAL. In
MANUAL mode, pressing the FAN SPEED button will change fan speed from low (1) to
high (6). In AUTO mode, the fan speed is controlled automatically. In cooling mode, the
controller automatically adjusts the fan speed to high, and as the inside temperature
approaches the set point, the fan speed will decrease.
