69-1538 38REPLACING THE BATTERIES (T8665C ONLY)IMPORTANTThree AA alkaline batteries are included with the thermostat. Batteries must be installed for programming and operation of the thermostat and the heating/cooling system.1. Install batteries in wallplate so positive terminals all point up (as shown).2. If the thermostat is already mounted on the wall, remove the thermostat by placing your thumb between the thermostat and wallplate and pulling the thermostat up and away as shown on the next page.M10622INSTALL 3 AA ALKALINE BATTERIES AS SHOWN, POSITIVE (+) TERMINALS TOWARD TOP.WALLPLATEBRRCOWYGDay
39 69-15383. When batteries are running low, a REPL BAT message flashes for one to two months before batteries run out com-pletely. Replace batteries as soon as pos-sible after message flashes.MPORTANTAlthough thermostat has a low battery indicator, replace batteries yearly to prevent leakage and thermostat and heating/cooling system from shutting down due to lack of thermostat battery power.4. If you insert new batteries within 20 to 30 seconds of removing old batteries, the system retains current time and day. If the display is blank, batteries are dead or installed incorrectly. You must reset time and day. See Setting the Clock section.As a precaution, when leaving home for longer than a month, change batteries before leaving to prevent system shutting down due to lack of power.M164248090706090807060
69-1538 40Always use fresh alkaline batteries. Non-alkaline batteries do not last as long and can leak, causing damage to the thermostat and wall surface.ADAPTIVE INTELLIGENT RECOVERY™ CONTROLYour new thermostat is so smart, it’s almost human. You perceive temperature from a variety of sources, not only from the air in the room, but also from your surrounding walls, windows and furnishings. Humans feel differences in temperature as slight as two degrees Fahrenheit. Common household thermometers and standard thermostats sense only air temperature, which may not reflect how hot or cold the room actually new thermostat reads both the temperature of the wall and in the air, and responds to temperature changes as little as one degree Fahrenheit, so room temperature is more likely to feel right to you and your family.The thermostat acts like a computer. When calculating the time to turn on your heating or cooling system, it considers air temperature, wall temperature, and the time you want to reach the comfort temperature. After considering these three things, Adaptive Intelligent Recovery™ control gradually changes the temperature from the energy savings setting to the comfort setting (for example, from a heating temperature of 62° at night to 70° in the morning).The system runs continuously until the comfort temperature you choose is reached without overshooting the setting. This saves energy.
41 69-1538How do you know when the system is in recovery? The thermostat displays “Recovery” whenever the thermostat activates Adaptive Intelligent Recovery™ control. (See display.) “Recovery” displays during recovery time from Sleep to Wake and from Leave to Return.After installation or new schedule programming, your thermostat learns from experience. Each day it checks how closely it hit the recovery target (for example, 70° at 6:00 AM) and adjusts the next day’s recovery start time accordingly. After four to eight days, the thermostat has adjusted to local weather, your lifestyle, the construction of your home, and your heating and cooling system. Optimum Comfort and Energy SavingsIn Fig. 3, Adaptive Intelligent Recovery™ control starts to recover at 5:00 AM and reaches the comfort temperature of 68° at 6:30 AM. Recovery time varies with the starting temperature and the comfort temperature you choose.AutoSystemFanWakeMonAMRoom RecoverySet ProgramSet Day/TimeEm Ht Aux HtHeatM20895
