1. A non-transitory computer-readable medium storing instructions for performing a method of conserving energy in a system, the method comprising:

  • determining a base setpoint value for a thermostat;

    receiving an indication of a duty cycling event having a duty cycling period;

    determining whether the duty cycling event is an offset-based duty cycling event;

    in response to determining that the duty cycling event is an offset-based duty cycling event,determining a first offset value for the duty cycling event,determining whether the system is in cooling mode,in response to determining that the system is in cooling mode,determining a first offset setpoint value based at least in part on the base setpoint value and the first offset value, andmodulating a setpoint of the thermostat between the determined base setpoint value and the first offset setpoint value, andin response to determining that the system is not in cooling mode,determining a second offset setpoint value based at least in part on the base setpoint value and the first offset value, andmodulating the setpoint of the thermostat between the determined base setpoint value, the second offset setpoint value, and a third offset setpoint value; and

    in response to determining that the duty cycling event is not an offset-based duty cycling event,modulating the setpoint of the thermostat between a fixed offset setpoint value and the base setpoint value.
