A22-2453-70 Ranco SPDT Air Conditioner Thermostat

Product code: 2700144

The function of the A22-2453 Adaptable Control is to cycle an SPDT switch in response to changes of temperature.
Switch is operated by the expansion and contraction of the bellows in response to temperature sensing by a cross ambient fill bulb and capillary. Range adjustments are limited to the rotation of the dial for the required temperature set point. Differential screw adjustment in the insulator block is for factory calibration use only and is NOT to be adjusted in the field.
