1 If wires will be connected to both RC and R on the new thermostat, remove metal jumper wire between RC and R. Leave metal jumper wire in place if only one of the terminals, RC or R, will be connected on the new thermostat.
2 If wires were connected to both R and RH terminals on the old thermostat, remove metal jumper wire between RC and R on the new thermostat. Connect the old R to the new RC and the old RH to the new R.
3 If two C and/or C1 wires were connected to the old thermostat, do not connect them to the new thermostat. Wrap the bare end of each wire separately with electrical tape and do not use.
4 If one C and/or C1 wire was connected to the old thermostat, the wire should be connected to the “C” letter designation on the new thermostat.

Understand Temperature Recovery Feature
Your thermostat comes with a feature called Adaptive Intelligent RecoveryTM, which eliminates all guesswork when setting your schedule. How long does it take the furnace to warm your house in the morning before you get out of bed or how long does it take the air conditioner to cool your house in the afternoon before you return from work? No problem. The thermostat determines that for you.
Simply set your program schedule to the time you want the house to be at your comfort temperature. The thermostat then turns on the heating or cooling at just the right time to have your home reach your scheduled temperature at your scheduled time.
For example–you get out of bed at 6:00 AM and want the temperature to be 70°F. Set the Wake period for 6:00 AM and 70°F. The thermostat then turns on the heat before 6:00 AM to raise the temperature to 70°F by 6:00 AM.
The thermostat alerts that the heating or cooling system is coming on before a scheduled time when “Recovery” shows on the screen.

It takes about a week for the thermostat to adjust to local weather, your schedule, the construction of your home and your heating and/or cooling system. Each day it adjusts the next day’s recovery start time accordingly.

Review Battery Tips
1. Replace the batteries as soon as LO Batt flashes in the display. The LO Battery indicator flashes in the display one month before the batteries run down completely.
2. Always use fresh AA alkaline batteries. Non-alkaline batteries do not last as long and can leak, causing thermostat damage.
3. Although the thermostat has a Low Battery indicator, replace the batteries once a year to prevent the thermostat and heating/cooling system from shutting down due to lack of battery power.
4. As a precaution, replace the batteries when leaving your home for more than a month to prevent your heating/cooling system from shutting down if the batteries run down completely.
