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 38.
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.
A Note About Programmable Fan:
The programmable fan feature will run the fan continuously during any
