Overriding Your Comfort Schedule
There are two ways to override your comfort schedule.

By pressing the HOLD/END button to turn on the HOLD icon, the
thermostat will maintain the current temperature settings and
ignore the comfort schedule for an indefinite period of time. The
word HOLD will appear in the display. Press the HOLD/END
button a second time and the thermostat will return the temperature
settings to the programmed comfort schedule. Pressing
HOLD/END will not alter your programmed comfort schedule.
Method 2 — Temporary Override

temperature setting will appear on the display. Pressing the UP or
DOWN button again will temporarily change the setpoint as
needed. At the next programmed time, the programmed comfort
schedule will resume.
AUXILIARY AND EMERGENCY HEAT
Auxiliary Heat
If the system has determined that it’s too cold outside for your heat
pump to heat the house without help, the AUX HEAT icon will
indicate that the system is getting help from the electric heaters.
This happens automatically.
Emergency Heat (EMHT)
If the heat pump is not working properly, you can manually turn
on the emergency heat by pressing MODE until EMHT appears.
You’ll know there’s a problem if the house can’t seem to get warm
when it’s cold outside. You want to avoid using emergency heat
continuously, though, because it’s the most expensive option. If
you suspect a problem with your heat pump, call your heating and
cooling dealer immediately.
CHANGING BATTERIES
In some situations, two AA batteries are the power source for the
thermostat. If batteries are used with your equipment, then they
should last about one year. As the batteries lose their power, a
battery icon appears on the display showing one black bar and then
none. As the icon becomes empty, you will begin to lose
thermostat functions because the batteries are losing their power.
When the batteries are completely dead, you won’t be able to use
the thermostat.
When using batteries for power, we recommend you replace them
with two AA alkaline batteries. They are in a compartment under
the removable faceplate of the thermostat.
You do not have to
remove the thermostat from the wall to replace the batteries
Simply use your thumb and forefinger to grasp and pull the
branded faceplate away from the thermostat to expose the batteries.
Lift out the batteries, and replace them.
Be sure to orient batteries in the direction indicated by the
embossed symbols shown on the plastic.
