Mount control to a flat surface with screws through holes provided in back of frame.

Important: On rough mounting surfaces, use the top two mounting holes only. When these controls are mounted on an uneven surface using screws in all four holes, the case can be twisted enough to affect the thermostat’s calibration and operation.

Mount the control where it is exposed to the average temperature of the controlled space. Do not mount where it will be affected by unusual heat or cold, such as directly over an animal stall, in sunlight, or on an outside wall. Avoid locations near a door, window or hay chute.

Important: Do not dent or deform the sensitive bulb of this thermostat. A dent or deformation will change the calibration and cause the thermostat to cycle at a temperature lower than the dial setting.
