On a Honeywell thermostat, “recovery” refers to a function that allows the system to efficiently return to a programmed temperature setting after a period of setback. This function typically operates after a period when the thermostat has been set to a lower temperature during cooler months (or a higher temperature during warmer months) to save energy. For example, if a thermostat is programmed to lower the temperature to 62F overnight and then return to a daytime temperature of 70F at 7:00 AM, the recovery function ensures the desired 70F is reached by the specified time. It achieves this by initiating the heating process before 7:00 AM, calculating the required lead time based on factors such as the current temperature, the desired temperature, and the system’s heating rate.
The implementation of this automated return-to-temperature setting is beneficial because it optimizes energy consumption without sacrificing comfort. Without it, the system would only begin heating at the set time, potentially leaving the space at an undesirable temperature for a period. This feature balances energy savings and user comfort, offering cost-effective climate control. This is especially relevant in modern homes and offices where occupancy schedules are predictable and energy conservation is a priority.
