4)Energy Management Recovery: (this step is skipped if configured to be non-programmable).

Energy Management Recovery (E) On enables the ther- mostat 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: If E On is selected 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 set temperature.

5, 6 & 7) Cycle Rate Selection – The factory default settings with SS/HP switch in SS position for Heat is medium cycle (ME) and Cool is fast cycle (FA). For Heat Pump (HP), the default setting is fast cycle (FA).

To change cycle rate, press the or key. Cycle rate differentials for different settings are:

MODE		Fast	Medium	Slow
		FA	ME	SL
Heat	(SS)	0.4°F	0.6°F	1.8°F
Cool	(SS)	1.2°F	–	1.7°F
Heat Pump (HP)		1.2°F	–	1.7°F

8)Select Compressor Lockout CL OFF or ON – Selecting CL ON will cause the thermostat to wait 5 minutes 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 lockout feature is already present in their system. When the thermostat compressor time delay occurs, it will flash the setpoint for up to five minutes.

9)System Mode Configuration – This thermostat is configured for Heat and Cool with Auto changeover (SYSTEM switch with Cool Off Heat Auto) default. It can also be configured for Heat and Cool (Cool Off Heat), Heat only with fan (Off Heat), Heat only without fan, Auto only (Auto Off), and Cool only (Cool Off).

10)Select Backlight Display – The display backlight improves display contrast in low lighting conditions. When the "C" termi- nal 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 whether the backlight is selected ON or OFF.

11)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.

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

13)Select Filter Replacement Reminder and Set Run Time. Select the "Change Filter" reminder On or OFF. If selected On, press MENU to select the time period from 25 to 1975 hours in 25 hours increments. In a typical system, 200 hours (default) of run time is approximately 30 days. After the se- lected time of blower operation, the thermostat will display "Change Filter" as a reminder to change or clean your air filter. When "Change Filter" is displayed, press MENU but- ton to clear the display and restart the time to the next filter change.
