WC A U T I O N • • Do not exceed ratings of the device(s). • Thermostats with guards that restrict air flow must have heating or cooling anticipation. The thermostat is not designed for service in any location where condensation may occur. Avoid locations where excessive moisture, corrosive fumes, or vibration is present. NEMA Type 1 covers are intended for indoor use primarily to provide a degree of protection against contact with the enclosed equipment.

WC A U T I O N Do not breathe on the thermostat or handle excessively as this affects the accuracy of the final calibration. 3. If the contact blade is made to the left (red lead) contact, use a 1/8" blade screwdriver to turn the calibration screw counterclockwise (looking at head of screw) until the blade floats between the contacts. NOTE Each complete turn of the screw changes calibration approximately 15°F (8°C). 4.
