12EMER is displayed flashing when the system switch is in EMER position.
13Alternately displays current time and temperature.
14The word HOLD is displayed when the thermostat is in the HOLD mode.
15Displays currently programmed set temperature (this is blank when SYSTEM switch is in the OFF position).
16“BATT” is displayed when 2 “AAA” batteries are low and should be replaced.
Configuration Menu
The configuration menu allows you to set certain thermostat operating characteristics to your system or personal requirements. 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 chart summarizes the configuration options. 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.In the run mode, if the setpoint temperature is manually raised by 3°F (2°C) or more above the actual temperature with the TEMPERATURE UP key, and the fast second stage feature is enabled, FA on, the second stage will energize immediately.
With FA off, second stage will not energize until the setpoint temperature is 1°F or more above actual temperature for more than ten minutes.
2.Select Compressor Lockout CL OFF or ON – Selecting CL 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
and heating cycles. This is intended to help protect the compressor 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 lockout feature is already present in their system. When the thermostat compressor time delay occurs it will flash the Snowflake and Flame icons for about five minutes.
3.Select Temperature Display Adjustment 3 LO to 3 HI – Allows you to adjust the room temperature display up to 3° higher or lower. Your thermostat was accurately calibrated at the factory but you have the option to change the display temperature to match your previous thermostat. The current or adjusted room temperature will be displayed on the left side
of the display.
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 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.
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.
•°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.
