A Note About Programmable Fan:
The programmable fan feature will run the fan continuously during
any time period when it is programmed to be on. This is the best way to
keep the air circulated and to eliminate hot and cold spots in your
building. If using IAQ mode, set fan to IAQ for any time period.

Temporary Hold: The thermostat will display HOLD and RUN SCHED
on the bottom of your screen when you press the

temporarily for a selected amount of time. After this, the program
setpoint will then replace your temporary setpoint.
Permanent Hold: With a temporary hold set, if you press the HOLD
key at the bottom of your screen, you will see HOLD appear below
the setpoint temperature in the display. The thermostat will now
permanently stay at this setpoint and can be adjusted using the
or keys.
