Example of thermostat display. 9 69-1536­3 ADAPTIVE INTELLIGENT RECOVERYTM CONTROL Your 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 feels to you. Your 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 10 RecoveryTM 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 until the comfort temperature you choose is reached without overshooting the setting. This saves energy. How do you know when the system is in recovery? The thermostat displays "Recovery" whenever the thermostat activates Adaptive Intelligent RecoveryTM control. See Fig. 3. So, "Recovery" displays during the recovery time from Sleep to Wake and from Leave to Return. System Heat Recovery AM Mon Sleep Room Heat Fan Auto M20148 Fig. 3. Example of "Recovery" indication. 69-1536­3 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 Savings In Fig. 4, Adaptive Intelligent RecoveryTM 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. 11 69-1536­3 At 7:00 AM System Operating in Comfort Mode System Heat AM At 6:00 AM Recovery Continues Fan Mon Wake Room Auto TEMPERATURE System Heat Recovery AM At 5:00 AM Recovery Continues System Heat Fan Mon Sleep Room Auto Recovery AM 1 Fan At 4:00 AM Recovery Begins System Heat Mon Sleep Room Auto Recovery AM Fan Mon Sleep Room Auto ENERGY SAVINGS PERIOD RECOVERY FROM ENERGY SAVINGS TIME COMFORT PERIOD THE THERMOSTAT USES THE SAME SCHEME TO RETURN GRADUALLY TO LOWER COMFORT TEMPERATURE DURING THE COOLING SEASON. 1 IF Recovery IS DISPLAYED, PRESS TO SEE THE COMFORT SETPOINT.

By now you may be wondering how to program your thermostat and how to use some more time and energy-saving features. First, let's look at features you'll be using often, like setting the System and Fan keys, how to override the current programming mode or to hold the thermostat at a specific temperature while you go on vacation. You can even program the thermostat to return to your regular programming schedule on your last day of vacation so you are comfortable when you return and yet save energy while you are away. Setting System and Fan Keys Use the System and Fan keys to change the system and fan settings. The fan settings can be set for each schedule period individually. The system selection is for all the schedule periods. CAUTION Equipment Damage Hazard. Can cause permanent damage to the compressor or other equipment. To avoid possible compressor damage, allow the compressor to remain off for five minutes before restarting. To avoid possible equipment damage, do not operate cooling when the outside temperature is below 50°F (10°C). See equipment manufacturer instructions. 13 69-1536­3 Setting the System Key Press the System key until the desired system (Heat, Off, Cool, or Auto) displays. System Setting the Fan Key Press Fan key until the desired mode (On or Auto) displays: Fan Heat: The thermostat controls the heating. Off: Both the heating and cooling are off. Cool: The thermostat controls the cooling. Auto: The thermostat automatically changes between heating and cooling operation, depending on the indoor temperature. Thermostat will satisfy system demand on a first call basis. For example, if zone 2 (any zone) is calling for heating ZONING and then zone 1 (any zone) asks for cool ­ the system will satisfy zone 2 before turning on the cool for zone 1. On: Fan operates continuously. Auto: Fan operates only when heating or cooling. displays when the thermostat is calling for the fan in this zone. NOTE: The thermostat may delay turning on the fan until another zone ZONING has completed its call for heat or cool before initiating the fan call for this zone. 14 69-1536­3 Setting Temporary Temperatures You can override the current schedule period to temporarily change the temperature setting until the next schedule period, or you can change and hold the temperature setting indefinitely. You can also change the temperature setting until a designated day and period (for example, while you are on vacation). Changing Temperature to Temporary Setting Until Next Schedule Period Press increase or decrease until the desired temperature setpoint displays. The temporary temperature setting you select displays for approximately three seconds. The display reads "Temporary" until the next period begins or when you cancel the temporary temperature setting. Temporary Setting M14563 While selecting a temporary setting, only the setpoint displays. 15 69-1536­3 Press the Run Program key to cancel the temporary temperature setting before the designated time.

Batteries must be installed for programming and operation of the thermostat and heating (cooling system). The batteries are located in the wallplate. See illustration. WALLPLATE IMPORTANT Although the thermostat has a low battery indicator, replace the batteries once a year to prevent leakage and to prevent the thermostat and heating/cooling system from shutting down due to lack of battery power in the thermostat. 1. When the batteries are running low, a REPL BAT message flashes from one to two months before the batteries run out completely. Replace the batteries as soon as possible when the message flashes. B R RC O W Y G INSTALL 3 AA ALKALINE BATTERIES AS SHOWN, POSITIVE (+) TERMINALS TOWARD TOP. M10622 21 69-1536­3 2. Remove the thermostat by placing your thumb between the thermostat and wallplate and pulling the thermostat up and away as shown. If you insert new batteries within 20 to 30 seconds of removing the old batteries, the system retains the current time and day. If the display is blank, the batteries are dead or installed incorrectly. You must reset the time and day. Refer to Setting the Clock section for instructions. As a precaution when leaving home for longer than a month, change batteries before leaving to prevent the system from shutting down due to lack of power. Always use fresh alkaline batteries. Nonalkaline batteries do not last as long; they also can leak, causing damage to the thermostat and the wall surface. Honeywell recommends Energizer® batteries. 70 80 60 90 70 80 M16424 22 90 60 69-1536­3 Using the (Information) Key AM System Heat The (information) key provides information at your fingertips.

Each day can be the same or different. Program Periods: WAKE The program period when you want the house at a comfortable temperature when you get up and while you get ready for work or school. (This is a higher temperature during the heating season and a cooler temperature during the cooling season.) LEAVE The program period you can set for an energy saving temperature while you are away at work or school. (This is a lower temperature during heating season, and higher temperature during cooling season) and it follows the WAKE period. RETURN The program period when you want the house at a comfortable temperature for activities before bedtime. (This is a higher temperature during the heating season and a cooler temperature during the cooling season) and it follows the energy-saving LEAVE period. SLEEP The program period you set for an energy-saving temperature while you are sleeping. (This is a lower temperature during heating season, and higher temperature during cooling season) and it follows the RETURN period. 28 69-1536­3 7-Day Preprogrammed Schedule Your thermostat is preprogrammed with the schedule shown in Table 1 (same schedule for all days of the week). You may keep this schedule or develop your own. Before starting the programming procedure, use Table 2 to plan your schedule. Instructions: 1. Write the time you want for each program period. 2. Write the heating and cooling temperatures you want for each period. 3. Draw a circle around the fan operation you desire for each period. Table 1. 7-Day Preprogrammed Schedule.
