Abstract
A condensate pump for an HVAC system includes a reservoir for collecting condensate water, a pump motor connected to an impeller pump for pumping the condensate water out of the reservoir, and a floatless pump controller. The floatless pump controller detects the water level in the reservoir and, based on the water level in the reservoir, controls the operation of the pump motor, and if necessary, sounds an alarm and shuts down the HVAC system. The floatless pump controller may employ an ultrasonic transducer or capacitance sensors to detect the level of condensate water in the reservoir.
