COPY DAY FUNCTION—This feature allows a selected day’s program to be copied to the desired days’ program- ming. To use this feature in view PRGM mode, select the day to be copied from by pressing HOLD key. Enter the program for the selected day as described in PROGRAMMING YOUR THERMOSTAT. To enter the copy mode, press the TIME key for greater than 4 seconds. The LCD should display COPY, the selected day of the week and the day (flashing) to be copied to. Press the HOLD key to select the day to be copied to. Press TIME to execute copy day operation and return to view program mode. Press RUN key to exit.

6 CONFIGURATION MENU

The configuration menu allows you to set certain thermostat operating characteristics to your system or personal require- ments.

Press RUN to make sure the thermostat is in the run program mode, then press PRGM and RUN at the same time to enter the configuration menu. The display will show the first item in the configuration menu.

The configuration menu table summarizes the configuration op- tions. An explanation of each option follows.

Press HOLD to change to the next menu item or press TIME to go backwards to the previous item in the menu. To exit the menu and return to the program operation, press RUN. If no keys are pressed within fifteen minutes, the thermostat will revert to normal operation.

1)Select FA or SL (Fast or Slow) Heating Cycle Rate—The FA setting is frequently used for gas, oil or electric heat. The SL setting produces a longer heating cycle which is normally for hot water or steam (hydronic) systems. Both settings produce very accurate temperature control and can be set to

your personal preference. FA cycles the system just under 1°F and the SL setting cycles at approximately 1.5F°.

2)Select backlit display—The display backlight improves display contrast in low lighting conditions. Selecting backlight ON will keep the light on for a short period of time after any key is pressed. Selecting OFF will keep the light off.

3)Select Energy Management Recovery OFF or ON— Energy Management Recovery (EMR) causes the thermo- stat 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.

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. Cooling allows more time per degree because it takes longer to reach temperature.

4)Select Compressor Lockout LOC OFF or ON—Selecting LOC ON will cause the thermostat to wait 5 minutes before turning on the compressor if the heating and cooling system loses power. It will also wait 5 minutes minimum between cooling cycles. This is intended to help protect the compres- sor from short cycling. Some newer compressors already have a time delay built in and do not require this feature. Your compressor manufacturer can tell you if the feature is already present in their system. When the compressor time delay

occurs it will flash the 6 CONFIGURATION MENU for about five minutes then turn on the compressor.

5)Select Temperature Display Adjustment 4 LO to 4 HI— Allows you to adjust the room temperature display 4° higher or lower. Your thermostat was accurately calibrated at the factory but you have the option to change the display tem- perature to match your previous thermostat.

6)Select F° or C° Readout—Changes the display readout to Centigrade or Fahrenheit as required.

7 PROGRAMMING 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.

When heating (cooling) your building, program the tempera- tures 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 button to begin running the factory preset program.

If you want to change the preprogrammed times and tempera- tures, follow these steps.

Determine the time periods and temperatures for each day programs. You must program four periods for each day program.
