Carrier® Condensate Overflow Switch Accessory

FEATURES

The condensate overflow switch accessory kit includes an electronic controller and sensor for use in 3-28 ton light commercial rooftop units. The sensor can be used in downflow or side discharge units to shutdown the unit depending on the unit controller, after 120 seconds of constant water contact, if the drain trap becomes plugged. It requires 2 minutes to reset after the water has cleared. See Table 1 for sensor control logic.
