This thermostat has been pre-programmed to provide optimal energy savings. No programming is necessary. We recommend you run these programs for a few days before adjusting your programming. If it is necessary to change these settings, use the scheduling table on the next page to record your new settings. You will also find the default schedule there as well.

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 firmly and pulling straight back, (Figure 1a). The batteries are located in the backside of the thermostat. The thermostat requires 2 (AA) alkaline 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 filter to see if it needs to be replaced. To reset this counter see page 32.

3. Auxiliary Heat: On multi-stage heat pumps this alert indicates your second stage heat is running.

Energy Saver Bar

The Energy Saver Bar indicates estimated energy savings. The preset schedules in the thermostat have been designed to give you optimal energy savings, five bars. Altering these schedules has a direct impact on the energy saver indicator. Altering the temperatures and/or times that the schedules run could decrease the estimated energy savings.

1. Example 1 shows the thermostat running the default schedules in the thermostat.
2. Example 2 shows the thermostat running altered schedules. This example could indicate the “At Home” schedule running for a longer time frame, or the temperatures may have been altered to where there is less of a gap between the “At Home” and “away” or “Asleep” temperatures.

Note: The Energy Saver Bar is only to be used as a guide to potential energy savings. Due to varied energy consumption costs, regional temperatures, and personal comfort levels, this bar cannot be equated into actual dollar or energy amounts.
