Carrier’s 7-day, 5/2-day, or 1-day commercial programmable thermostats offer flexibility, quality, and reliability. The wall-mounted, low-voltage thermostat maintains room temperature by controlling the operation of an HVAC (heating, cooling and ventilation) system. Separate heating and cooling set points and auto-changeover capability allow occupied and unoccupied programming for energy savings. Humidity sensing model allows control of humidity along with room temperature.
