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.
Your thermostat can be programmed to have each day of the week
programmed uniquely (7 days) or non-programmable. For the 7-day
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)
This thermostat has a programmable fan feature, which allows you to run the
fan continually during any time period.
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.
Staging Delay Note: This step will not appear if using an outdoor
balance point temperature.

A Note About Auto Changeover:
In Auto you have the ability to switch between Auto Heat or Auto Cool
by pressing the system key. This can be done once the current mode has
reached its setpoint. For example: if in Auto Heat, the heat setpoint must
be satisfied before the thermostat will allow you to switch to Auto Cool.
You can switch out of Auto by holding down the system key. To get back
into Auto, you must toggle the system key to Auto.
