ADAPTIVE HEAT PUMP RESISTANCE HEAT CONTROLLER
First Claim
1. An electrical heating apparatus, comprising:
- a primary heating stage heat pump;
a secondary heating stage resistance heating circuit having a plurality of heating elements;
an adaptive resistance heat controller connected to said resistance heating circuit, said adaptive resistant heat controller including a duty cycle monitor that monitors a duty cycle of said electrical heating apparatus, said controller selectively energizing one or more of said plurality of heating elements in response to changes in said duty cycle so as to provide adaptive heating control to meet actual heating demand while reducing overall peak energy consumption; and
a two-stage thermostat connected to said controller.

Abstract
An electrical heating apparatus includes a primary heating stage heat pump, a secondary heating stage resistance heating circuit having a plurality of heating elements, an adaptive resistance heat controller and a two-stage thermostat. The adaptive resistance heat controller is connected to the two-stage thermostat heat pump and resistance heating circuit. The adaptive resistance heat controller includes a duty cycle monitor that monitors the duty cycles of the thermostat primary and secondary stages. The controller selectively energizes one or more of the plurality of heating elements in response to changes in the duty cycles so as to provide adaptive heating control to meet actual heating demand while reducing overall peak energy consumption.
