1. For the thermostat guard, refer to G Series Thermostat and Humidistat Guards Catalog Page, LIT-1922145.
2. Can also be used where one unit provides both heating and cooling by adding a jumper between terminals 2 and 3. (See Typical Wiring Diagram and Electrical
Ratings for Line Voltage Thermostats Catalog Page, LIT-1922600.)
3. Includes a faceplate for horizontal mounting. The plate is for on-the-job installation over a vertical plate.
Can field-convert to other configurations.
