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.
