A digital setback thermostat automatically adjusts temperature settings when a space is unoccupied. In hospitality environments, this helps reduce energy use in empty guestrooms while maintaining comfort when rooms are in use.
The best setback temperature depends on your property’s comfort standards, HVAC system, and operating goals. Many hotels set limits that balance guest satisfaction with energy conservation, using programmable ranges configured by qualified staff.
Optimax ST includes a built-in passive infrared motion sensor, supporting automatic setback operation based on room occupancy.
In guestrooms, Thermostats perform best when installed in an open area with normal room activity. Proper placement helps ensure accurate motion detection and consistent temperature control.
HotelTech works directly with hospitality teams to match the right model, support your setup, and deliver a thermostat built for guestroom performance.
