- 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.

Abstract
A facility for performing setpoint adjustment-based duty cycling techniques by adjusting the setpoint of a device or component is described. The facility reduces energy consumption for a system, such as an HVAC system, or device by adjusting or modulating an associated setpoint or temperature setting. The facility modulates the setpoint between a base setpoint value and another setpoint value based on a mode of the system. When the system is in a cooling mode, the facility modulates the temperature between the base setpoint value and a higher setpoint value. When the system is in heating mode, the facility modulates the temperature between the base setpoint value and a lower setpoint value. The facility may modulate the setpoint between the two setpoint values based on an offset value or a fixed setpoint value.
