    THERMOSTAT LOCATION To ensure proper operation, the thermostat should be mounted on an inside wall in a frequently occupied area of the building. In addition, its position must be at least 18" (46 cm) from any out- side wall, and approximately 5', (1.5 m) above the floor in a location with freely circulating air of an average temperature.

    REMOVING THE THERMOSTAT FROM THE SUBBASE 1. Insert a flat blade screwdriver or coin 1/8" into the slot located in the bottom center of the thermostat case and twist 1/4 turn. When you feel or hear a click, grasp the case from the bottom two corners and sep- arate from the subbase as shown in the dia- gram at the left.
