What Does Hold Mean On Honeywell Thermostat

Complete Explanation

On a Honeywell thermostat, the “Hold” function is a command that instructs the device to ignore its programmed schedule and maintain a specific temperature indefinitely or for a set duration. This feature is primarily used when a resident’s routine changes, such as during a holiday or an unexpected guest visit, requiring a deviation from the standard heating or cooling cycle.

• Permanent Hold: This setting locks the thermostat at the current temperature. The system will not return to the programmed schedule until the user manually presses the “Run Schedule” or “Cancel Hold” button.
• Temporary Hold: This setting maintains a specific temperature until the next scheduled time period begins. Once the next programmed time block is reached, the thermostat automatically reverts to the pre-set temperature for that period.
• Manual Override: By adjusting the temperature arrows while a schedule is active, many Honeywell models will automatically enter a temporary hold state to provide immediate comfort.

History / Background

The evolution of the “Hold” function coincides with the transition from manual bimetallic strip thermostats to programmable digital controllers. In the late 20th century, as energy efficiency became a priority, programmable thermostats were introduced to lower temperatures during sleep or away hours. However, static schedules often failed to account for the unpredictability of human behavior. The “Hold” feature was developed as a necessary user-interface solution to provide flexibility, allowing users to benefit from energy-saving schedules without being locked into a rigid temperature regime.

Importance and Impact

The Hold function significantly impacts both user comfort and energy consumption. By allowing for a “Permanent Hold,” users can prevent pipes from freezing during winter vacations by setting a minimum temperature regardless of the daily schedule. Conversely, the “Temporary Hold” prevents the common issue of a thermostat switching back to a high heat setting while a user is still asleep, thereby reducing unnecessary energy expenditure and wear on the HVAC system.

Why It Matters

Understanding the distinction between hold types is critical for homeowners to avoid unexpected utility bills or discomfort. A user who accidentally activates a Permanent Hold may find their home too hot or cold the following day because the system failed to transition to the scheduled night or day settings. Proper use of the Hold feature ensures that the HVAC system operates efficiently while remaining adaptable to the user’s immediate needs.
