Alerts
This chapter will outline the various alerts the thermostat will report to
you and how to respond to them.
1. Low Battery: This icon will appear 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, (Figure
1a). The batteries are located on 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 icon appears on the screen, it indicates
you should check your furnace lter to see if it needs to be replaced.
