5 CHECK THERMOSTAT OPERATION

CONTINUED FROM THIRD PAGE

Before you begin programming your thermostat, you should be familiar with its features and with the display and the location and operation of the thermostat buttons. Your thermostat consists of two parts: the thermostat body and the base. To remove the body, gently pull it straight out from the base. To replace the body, line up the body with the base and press gently until the body snaps onto the base.

Operating Features

Now that you are familiar with the thermostat buttons and display, read the following information to learn about the many features of the thermostat.

•SIMULTANEOUS HEATING/COOLING PROGRAM STOR- AGE — 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 until the display shows the temperature you want. The thermostat will override current programming and keep the room tempera- ture 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

Figure 8. Thermostat display, buttons and switches

button. “HOLD” will be displayed. Then choose the desired

temperature by pressing or . The thermostat will hold the room temperature at the selected setting until you press the RUN button to start program operation again.

•ENERGY MANAGEMENT RECOVERY — Energy Manage- ment Recovery (EMR) causes the thermostat to start heating or cooling early to make the building temperature reach the

program setpoint at the time you specify. Heating will start 5 minutes early for every 1° of temperature required to reach

setpoint. Cooling will start approximately 15 minutes early for every 1° because it takes longer to reach temperature. Clipping W903 jumper will disable EMR.

Example: You select EMR and have your heating pro- grammed to 65° at night and 70° at 7 AM. If the building temperature is 65° the difference between 65° and 70° is 5° .

Allowing 5 minutes per degree the thermostat setpoint will change to 70° at 6:35 AM.

•° F/° C CONVERTIBILITY — The factory default setting is Fahrenheit. Clipping W904 jumper on the circuit board (see fig. 1) will alter this feature to Celsius temperature setting.

•LOW BATTERY INDICATOR — If the 2 “AAA” alkaline batter- ies are low and should be replaced, the display will be blank except for “LO BATTERY”. When the batteries are low, press- ing any button will cause the display to operate for ten seconds. After ten seconds, the display will return to blank except for “LO BATTERY”. After “LO BATTERY” has been displayed for 4 weeks, the thermostat will raise the temperature 10 degrees above your setpoint in COOL mode and will drop temperature 10 degrees below your setpoint in HEAT mode. You cannot program with low batteries, but you can override setpoint temperature.
