PART NO. 37-5323E Replaces 37-5323D 0004 INSTALLATION REMOVE OLD THERMOSTAT 1. Shut off electricity at the main fuse box until installation is complete. Ensure that electrical power is disconnected. 2. Remove the front cover of the old thermostat. With wires still attached, remove wall plate from the wall. If the old thermostat has a wall mounting plate, remove the thermostat and the wall mounting plate as an assembly. 3. Identify each wire attached to the old thermostat using the labels enclosed with the new thermostat. 4. Disconnect the wires from old thermostat one at a time. DO NOT LET WIRES FALL BACK INTO THE WALL. 5. Install new thermostat using the following procedures. ELECTRIC GAS Electric/Gas switch ELECTRIC HEAT OR SINGLE-STAGE HEAT PUMP SYSTEMS Figure 1. Back of thermostat base Read entire paragraph before setting electric heat switch. If you are unsure of your application, contact a qualified serviceperson. If you have a single-stage heat pump system, OR your system uses central electric heat, where the blower is energized by a separate circuit through the fan relay (meaning that the fan turns on immediately on call for heat), then the switch on the back of the thermostat base must be moved to the “ELECTRIC” position (see fig 1). If the thermostat is energizing electric heat sequencers, the switch MUST remain in the “GAS” position. Alkaline batteries (3 "AA"– install "+" ends to the left) Screw anchors If you must move the switch to the “ELECTRIC” position (to the left), use a small screwdriver or pencil. ATTACH THERMOSTAT BASE TO WALL W 1. Remove the packing material from the thermostat. Gently pull the cover straight off the base. Forcing or prying on the thermostat will cause damage to the unit. If necessary, move the electric heat switch (see ELECTRIC HEAT SYSTEMS, above). 2. Connect wires beneath terminal screws on base using appropriate wiring schematic (see figs. 3 through 10). 3. Place base over hole in wall and mark mounting hole locations on wall using base as a template. 4. Move base out of the way. Drill mounting holes. 5. Fasten base loosely to wall, as shown in fig. 2, using two mounting screws. Place a level against bottom of base, adjust until level, and then tighten screws. (Leveling is for appearance only and will not affect thermostat operation.) If you are using existing mounting holes, or if holes drilled are too large and do not allow you to tighten base snugly, use plastic screw anchors to secure subbase. 6. Push excess wire into wall and plug hole with a fire-resistant material (such as fiberglass insulation) to prevent drafts from affecting thermostat operation. RH RC B G Y O Mounting holes Figure 2. Thermostat base HYDRONIC (HOT WATER OR STEAM) HEATING SYSTEMS BATTERY LOCATION This thermostat requires 3 “AA” alkaline batteries to operate. Batteries are installed in the thermostat at the factory with a battery tag to prevent power drainage. You must remove the battery tag to engage the batteries and provide power to the thermostat. This thermostat is set to operate properly if you have a forcedair heating system. If you have a hydronic heating system (a system that heats with hot water or steam), you must set the thermostat to operate properly with your system. While in the HEAT mode, change the setting by pressing SET TIME/SET TEMP and VIEW PRGM buttons at the same time until the correct setting is displayed (A for forced air; H for hydronic systems). If there is a loss of battery power, or when you change batteries, you must repeat this operation once battery power is restored. If the word BATTERY is displayed, the batteries are low and should be replaced with fresh “AA” Energizer® alkaline batteries. To replace batteries, install the batteries along the top of the base (see fig. 2). The batteries must be installed with the positive (+) ends to the left. 2 JUMPER WIRE THERMOSTAT THERMOSTAT B Y O G W RC B RH Y O G W RC RH SYSTEM SYSTEM Heating System Figure 3.

Now you are ready to program your thermostat. This section will help you plan your thermostat’s program to meet your needs. For maximum comfort and efficiency, keep the following guidelines in mind when planning your program. • SIMULTANEOUS HEATING/COOLING PROGRAM STORAGE — When programming, you can enter both your heating and cooling programs at the same time. There is no need to reprogram the thermostat at the beginning of each season. • TEMPERATURE OVERRIDE — Press or • When heating (cooling) your building, program the temperatures to be cooler (warmer) when the building is vacant or during periods of low activity. • During early morning hours, the need for cooling is usually minimal. Look at the factory preprogrammed times and temperatures shown below. If this program will suit your needs, simply press the RUN PRGM button to begin running the factory preset program. until the display shows the temperature you want. The thermostat will override current programming and keep the room temperature at the selected temperature until the next program period begins. Then the thermostat will automatically revert to the program. • HOLD TEMPERATURE — The thermostat can hold any temperature within its range for an indefinite period, without reverting to the programmed temperature. Press HOLD TEMP/ADV DAY button. HOLD will be displayed. Then choose the desired hold temperature by pressing • • • • or FACTORY PREPROGRAMMING Cooling Program for Heating Program for ALL Days of the Week: ALL days of the Week: PERIOD 1st 2nd 3rd 4th . or TEMP 68°F 68°F 68°F 64°F PERIOD 1st 2nd 3rd 4th TIME 6:00 AM 8:00 AM 5:00 PM 10:00 PM TEMP 78°F 82°F 78°F 78°F If you want to change the preprogrammed times and temperatures, follow these steps. The thermostat will hold the room temperature at the selected setting until you press RUN PRGM button to start program operation again. °F/°C CONVERTIBILITY — Press SET TIME/SET TEMP and HOLD TEMP/ADV DAY buttons until the temperature display is in Celsius (°C). To display Fahrenheit (°F), repeat the process. 12-HOUR/24-HOUR CLOCK DISPLAY — The clock is set to display 12-hour time, which means that the clock will display AM and PM time (12:00 AM is midnight; 12:00 PM is noon). However, you may want to display a 24-hour clock (military-style time). The 24-hour clock display will show 1:00 PM as 13:00, 2:00 PM as 14:00, and so on. To change to the 24-hour clock display, press SET TIME/SET TEMP and RUN PRGM buttons at the same time. In the 24-hour clock mode, AM and PM are not displayed. LOW BATTERY INDICATOR — If the 3 “AA” alkaline batteries are low and should be replaced, the display will be blank except for the word BATTERY. When the batteries are low, pressing any button will cause the display to operate for ten seconds. After ten seconds, the display will be blank except for the word BATTERY. You cannot program with low batteries, but you can override setpoint temperature. TEMPERATURE DISPLAY ADJUSTMENT — Your new thermostat has been accurately set in our factory. However, if you wish, you may adjust your new thermostat temperature display to match your old thermostat. This can be accomplished (within a ±4° range) as follows: 1. Press VIEW PRGM and HOLD TEMP/ADV DAY buttons at the same time. 2. Press TIME 6:00 AM 8:00 AM 5:00 PM 10:00 PM 1. Determine the heating and cooling temperatures you want to use. You may select up to four heating temperatures (HEAT 1, HEAT 2, HEAT 3, and HEAT 4), and up to four cooling temperatures (COOL 1, COOL 2, COOL 3, and COOL 4). Use the table below to write down the temperatures you have selected. Heat Temperatures Cool Temperatures 1 2 3 4 1 2 3 4 Your selected temperatures* Factory pre-programmed 68°F 68°F 68°F 64°F 78°F 82°F 78°F 78°F temperatures* * You may only program heating temperatures you have selected into the heating program and cooling temperatures into the cooling program (for example, you cannot program the COOL 1 temperature into your heating program). You may program the temperatures you choose in any order, and you may use the same temperature in consecutive program periods (for example, you may program period 1 with temperature 1 and periods 2, 3, and 4 with temperature 2). You do not have to use all possible temperature choices (for example, you may want to select temperatures for HEAT 1 and HEAT 2 only – in this case, the HEAT 3 and HEAT 4 temperatures would stay the same as previously programmed). 2. Determine the time periods during which you will program the temperatures you have just selected. You must program four periods for each day (periods 1, 2, 3, and 4). However, you may use the same heating and cooling temperatures for consecutive time periods. Also keep in mind that, for any given day, you can only program one set of times for both heating and cooling (for example, if you select 5:00 AM to begin heating period 1 on Monday, then your cooling period 1 for Monday will also begin at 5:00 AM). However, you may select different time periods for each day separately (for example, heating/cooling period 1 on Monday may begin at 5:00 AM, but heating/cooling period 1 on Saturday may begin at 9:00 AM). Use the table on the following page to plan your program time periods, and the temperatures you want during each period. You may also want to look at the sample program table to get an idea of how the thermostat can be programmed. to adjust the displayed temperature to your desired setting. 3. Press RUN PRGM to resume normal program operation. • COPY DAY FUNCTION — This feature allows Monday’s program to be copied into the rest of the week’s programming. This feature is only available the first time you program your thermostat. To use this feature, simply enter the program for Monday as described in PROGRAMMING YOUR THERMOSTAT, and then press RUN PRGM. 5 Heating/Cooling Schedule Plan THIS THERMOSTAT ALLOWS ONE SET OF TIMES FOR BOTH HEATING AND COOLING Period 1 Heat Temp.
