摘要：
The disclosure provides a proportional control signal circuit (PCSC), an HVAC controller employing the same and an HVAC system including the HVAC controller. In one embodiment, the PCSC includes: (1) a signal input configured to receive a pulse width modulated signal, (2) a control input configured to receive an integration signal, (3) a signal output and (4) control circuitry, coupled to the signal input, the control input and the signal output, configured to provide either the pulse width modulated signal or a DC signal to the signal output based on the integration signal.
