Description
The Honeywell Q7300D1038 is a switching subbase used for two-compressor heat pump systems. It serves as a communication link between the thermostat and the control system of the heat pump and controls the two compressors. It positions the compressors depending on the need for heating or cooling and, in the process, maximizes efficiency and comfort. In HVAC systems that use dual-compressor heat pumps, this subbase enables the system to change between the stages seamlessly thereby avoiding fluctuation in temperatures and consequently damage to the equipment. Advantages are better system performance, energy saving due to staged operation, and better comfort due to constant temperature.
