Modifying Your Weekly Comfort Schedule

You are ready to set the new starting time for the morning period. One press of the TIME/TEMP button and you are ready to set the new morning temperature. To set values for other periods, use the PROGRAM button. To set values for other days, use the DAY button. Press HOLD/END and you are finished.

Overriding Your Comfort Schedule

There are two ways to override your comfort schedule.

Method 1 — Manual Operation

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

At the first press of the UP or DOWN button, the current 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.

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. As the batteries get weaker, the icon goes down to 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 lid on top of the thermostat. You do not have to remove the thermostat from the wall to replace the batteries. Simply open the lid, lift out the batteries, and replace them like you would any other battery operated device.

TROUBLESHOOTING

What if AUX HEAT appears on the display? (Heat pump model only)

If auxiliary heat is on, you will see AUX HEAT indicator in the display. When it is on this means the system has determined that it’s too cold outside for your heat pump to heat the house without help, so it’s getting help from the electric heaters. This happens automatically.

NOTE: This indicator does not mean there is a problem with your system.

What if E-Heat appears on the display?

If the heat pump is not working properly, you can manually turn on the emergency heat for extra help in heating. 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, though, because it’s the most expensive option. And, of course, if you suspect a problem with your heat pump, call your heating and cooling dealer immediately.
