Removing Stat from Quick-Mount Backplate
Use Thermostat Tool CCT735A (MQT735A) and the following
procedure to remove a stat from a Quick-Mount backplate:
1. Insert blade of Thermostat Tool between stat body and
backplate tab. Push in about 1/4 in. (Fig. 52).
2. Move Tool outward to lever stat body from backplate.
