Alerts
This chapter will outline the various alerts the thermostat will report to you and how to
respond to them.
1. Low Battery: This will appear in the message window when your batteries are
starting to run low on power and should be changed to avoid system interruptions,
(Figure 1). Change the batteries by gripping the sides of the thermostat rmly and
pulling straight back away from the wall, (Figure 1a). The batteries are located in
the backside of the thermostat. The thermostat requires 2 (AA) batteries to operate.
If you do not replace the batteries in a timely manner, the screen will go blank
except for the low battery warning, (Figure 1b). Your system will shut down and
will not operate until you replace the batteries. Replacing the batteries will clear
this alert.
Note: Settings will not be lost while replacing the batteries. They are stored in the
thermostat’s memory.
2. Filter Change: When this message appears on the screen, it indicates you should
check your furnace lter to see if it needs to be replaced. To reset this counter see
page 30.
