User’s Guide                         

Inside the hinged door of the thermostat is the SuperstatTM 

User’s Guide. This guide is designed to assist the installer in 

explaining to the end user how to operate their new thermo-

stat, as well as serve as a handy future reference for the end 

user.

We recommend that the installer fill out pages 1, 5, 7 and 8 

(where applicable) and explain to the user how the thermo-

stat operates, what settings may be changed, and how the 

time clock schedules are used.
