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)Not Available

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 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 your weekday and weekend programs. You must program four periods for both the weekday and weekend program. However, you may use the same heating and cooling temperatures for consecutive time periods. You can choose start times, heating temperatures, and cooling tem- peratures independently for both weekday and weekend programs (for example, you may select 5:00 AM and 70° as the weekday 1st period heating start time and temperature, and also choose 7:00 AM and 76° as the weekday 1st period cooling start time and temperature). Use the table at the bottom of the 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.
