Abstract

A method for regulating coolant temperature of an HVAC heat pump system with coolant heating. The method includes measuring temperature of coolant flowing through the system, and configuring a valve assembly of the system to direct coolant flow to a heater core from both an engine and an engine bypass line when temperature of the coolant is above a predetermined threshold.
