5.3I Temperature Cutout Programming

Ultra-Aire units produce heat when dehumidifying. Depending on outside conditions, the ventilation function may introduce warm air into the space. Occasionally, the operation of the Ultra-Aire may produce enough heat to drive temperatures up. The temperature cutout feature disables all Ultra-Aire operations if temperatures reach cutout setpoint. In most installations this

feature will not need to be used. If temperature cutout is desired, program the setpoint by pressing the “program enter” button. Press RH until “temp cutout” is flashing. Use “RH” up or “RH” down to adjust setpoints.
