Temporary and Permanent Hold
Feature
Temporary Hold:
The thermostat will display
HOLD and RUN SCHED on the bottom of your
screen when you press the + or - key. If you
do nothing, the temperature will remain at this
setpoint temporarily for four hours. Your program
setpoint will then replace your temporary setpoint.
Permanent Hold:
If you press HOLD key at the
bottom of our 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.
To return to program: Press the RUN SCHED
key at the bottom of your screen to exit either
temporary or permanent hold.
Filter Change and Other Reminders
If your installing contractor has configured the
thermostat to remind you when the air filter
needs changed, you will see FILT in the display
when your air filter needs changed. FILT will be
shown in the display after your system has run
long enough to require an air filter change.
Resetting the filter change reminder: When
FILT reminder is displayed, you should change
your air filter and reset the reminder by holding
down the third button from the left side of the
thermostat for three seconds.
Auto Changeover
If 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.
Programmable Fan
The programmable fan feature will run the
fan continuously during any time period 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 desired.
This thermostat also has other maintenance
reminders (Humidity Pad, UV Lamp and IAQ
Cell), that are reset with the same procedure.
