Thermostat Configuration Menu

setting on the remote. This is only used in areas where there are other wireless devices or electronic equipment that interfere with the default frequency of the thermostat/ remote sensor communication.

7)Programmable Periods – This control can be config- ured for 4, 2 or 0 programmable periods. The display indicates "PRG 4" in the display as default. The program- mable periods can be changed to 2 or 0 by pressing the

or keys. With "PRG 0" selected for non-program- mable, SYSTEM key selection will skip EMR (item 8) and temporary program override (item 15).

8)Select Energy Management Recovery OFF or ON – Energy Management 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 programmed 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 thermo- stat setpoint will change to 70° at 6:35 AM. Cooling allows more time per degree because it takes longer to reach temperature.

9)Fast or Slow Cycle Selection – The factory default setting is fast cycle, which cycles 1st stage at approxi- mately 1.2°F and 2nd stage 0.75°F. If you prefer slow

cycle, press the temperature key to change to SL. The 1st stage and 2nd stage would be 1.5°F and 1.2°F respec- tively.

10)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 manufac- turer can tell you if the lockout feature is already present in their system. When the thermostat compressor time delay occurs it will flash the setpoint for about five minutes.

11)Select Backlight Display – The display backlight improves display contrast in low lighting conditions. When the "C" terminal is powered, selecting backlight CdL ON will keep the light on continuously. Select backlight OFF will keep the light on momentarily after any key is pressed. When the "C" terminal is not powered, the light will be on momentarily after any key is pressed no matter the backlight is selected ON or OFF.

12)Select Fast Second Stage On or OFF – For Heat: During normal operation if the setpoint temperature is manually raised by 3°F or more above the actual tem- perature with the button, and the fast second stage feature is enabled, FA ON, the second stage will energize immediately.

For Cool: During normal operation if the setpoint tempera- ture is manually lowered by 3°F or more below the actual temperature with the button, and the fast second stage feature is enabled, FA ON, the second stage will energize immediately.

13)Select filter replacement run time – The thermostat will display "FLTR" after a set time of operation. This is a reminder to change or clean your air filter. This time can be set from 0 to 1950 hours in 50 hour increments. A selection of 0 will cancel this feature. When "FLTR" is displayed, you can clear it by pressing HOLD and RUN at the same time. This resets the timer and starts counting the hours until the next filter change. Contact your system manufacturer for a specific replacement/maintenance interval.

14)Select Temperature Display Adjustment 4 LO to 4 HI –

Allows you to adjust the room temperature display up to

4° 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.

15)Select Temporary Program Override Time – The thermo- stat can hold any temperature you set it to for the amount of time you select on this option. Your choices are 0:00 to 8:00 hours in 15 minute increments. 0:00 means disable.

Example:

1.You have selected 3:00 hours for the Temporary Pro- gram Override time period.

2.With the thermostat set to Heat or Cool, press HOLD for approximately 5 seconds until "HOLD time 3:00" (indicating 3 hours) appears as a setting reminder.

3.After releasing the button, "HOLD" on the display will blink.

4.Use or to set the temperature to your prefer ence. The thermostat will maintain this temperature setting for 3 hours with "HOLD" blinking to remind you it is in Temporary Hold. After 3 hours, the thermostat will go back to the program temperature and "HOLD"

will no longer blink or display.

16)Select F° or C° Readout – Changes the display readout to Celsius or Fahrenheit as required.

17)Limited Heat Range – This feature provides a maximum setpoint temperature for heat. The default setting is 90°F. It can be changed between 62°F and 89°F by pressing the or key.

18)Limited Cool Range – This feature provides a minimum setpoint temperature for cool. The default setting is 45°F. It can be changed between 46°F and 82°F by pressing the or key.

19)Comfort Alert – This feature is available in Passive mode on this thermostat. If a Comfort Alert module is connected, the thermostat will receive and flash the fault codes from the Comfort Alert module.

20 & 21) Keypad Lockout – This menu selection will display lock () icon. The and are used to toggle the function and display the lock icon and OFF (keypad not locked out, default) indicating in the time digits to the lock icon and ON (keypad locked out). When the keypad lockout function is enabled (ON), and the SYSTEM button is pressed again, the display will indicate the number 000 (default, still disabled) in the time digits. The and

are used to set the combination number from 0 to 999. If a combination of 000 is selected and the SYSTEM button is pressed, the menu will be exited and keypad will not be locked. If 1 to 999 is selected and the SYSTEM button is pressed again, the combination is locked into non-volatile memory and the menu is exited. The lock icon (to designate keypad locked with a valid combination) will display when the menu is exited. The SYSTEM button will operate for 10 seconds after the menu mode is exited to allow the user to change the mode from OFF to the desired system mode.

While the keypad is locked out, a simultaneous press of and will enter the menu item from any mode instead of only OFF mode. When the menu is entered with the keypad lockout feature enabled, the first menu item displayed is the combination code 0. The or keys are used to set the combination unlock number from 0 to 999. If the unlock number matches exactly with the combination lock number stored in memory when the SYSTEM button is pressed, the keypad is unlocked and the lock icon is removed. If the unlock number does not match when the SYSTEM button is pressed, menu is exited and the keypad remains disabled.

To reset the combination code and unlock the keypad if the code is forgotten, see troubleshooting section, page 16.
