First Claim
Patent Images
1. A method comprising:
- determining, by a controller comprising a processor, that a coil associated with a heat pump is subjected to a defrost cycle;
determining, by the controller, that at least one of;
a conditioned space is occupied, anda thermostat associated with the conditioned space indicates that an energy saving mode is not in use; and
enabling, by the controller, an auxiliary heat source based on the determination that the coil is subject to the defrost cycle and the determination that the conditioned space is occupied or the thermostat indicates that the energy saving mode is not in use.

Abstract
Embodiments are directed to determining, by a controller comprising a processor, that a coil associated with a heat pump is subjected to a defrost cycle, determining, by the controller, that at least one of: a conditioned space is occupied, and a thermostat associated with the conditioned space indicates that an energy saving mode is not in use, and enabling, by the controller, an auxiliary heat source based on the determination that the coil is subject to the defrost cycle and the determination that the conditioned space is occupied or the thermostat indicates that the energy saving mode is not in use.

11. An apparatus comprising:
-
at least one processor; and memory having instructions stored thereon that, when executed by the at least one processor, cause the apparatus to; determine that a coil associated with a heat pump is subjected to a defrost cycle, determine that at least one of; a conditioned space is occupied, and an energy saving mode is not in use in association with the conditioned space, and enable an auxiliary heat source based on the determination that the coil is subject to the defrost cycle and the determination that the conditioned space is occupied or that the energy saving mode is not in use. - View Dependent Claims (12, 13, 14, 15, 16)

17. A system comprising:
-
a sensor configured to provide an indication of whether a motion in an amount greater than a first threshold is detected within a second threshold amount of time; and a processor configured to; determine whether a coil associated with a heat pump is subjected to a defrost cycle, determine whether a conditioned space is occupied based on the indication provided by the sensor, and enable an auxiliary heat source that is located within the conditioned space when the coil is subject to the defrost cycle and when the conditioned space is occupied. - View Dependent Claims (18, 19, 20)
