Reminders

Once a reminder has been turned on and set, the elapsed time can be 

checked by navigating to its tech setup step.  The elapsed time will then 

appear in the text field.  It can also be reset at that time by holding down 

the set time/run sched button for 3 seconds.  Resetting an expired 

reminder can be done without entering tech setup, by holding down 

the set time/run sched button for 3 seconds from the home screen.

(If using programming)

All our programmable thermostats are shipped with an energy saving default 

program. You can customize this default program by following the 

instructions in the 

set program schedule section

 starting on page 24.

Programming

Your thermostat can be programmed to have each day of the week 

programmed uniquely (7 days), all the weekdays the same with a separate 

program for Saturday and a separate program for Sunday (5+1+1), or 

non-programmable. For the 7-day and 5+1+1 programming modes, there are 

three time period options. 

1. “4” Residential 

(WAKE, LEAVE, RETURN, SLEEP) 

2. “2C” Commercial 

(OCCUPIED, UNOCCUPIED) 

3. “4C” Commercial 

(OCCUPIED 1, UNOCCUPIED 1, OCCUPIED 2, UNOCCUPIED 2)
