First Claim
Patent Images
1. A setback thermostat for a gas engine heat pump, and a method for controlling the gas engine heat pump, said thermostat providing a load signal to a gas engine heat pump controller, the gas engine heat pump controller increasing or decreasing the gas engine heat pump'"'"'s operating level relative to said load signal, the thermostat ramping said temperature up when an increase in the setpoint occurs the method comprising the steps of:
- A. determining if a programmed setpoint change has occurred;
B. when a programmed setpoint change has occurred monitoring the load signal;
C. decreasing the ramp rate if auxiliary heat is turned on; and
F. returning to step A.
