4) Energy Management Recovery: (this step is skipped if
confi gured 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
Cycle rate differentials for different settings are:
MODE
Heat (SS) 0.4°F
Cool (SS) 1.2°F
Heat Pump (HP) 1.2°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 fl ash the setpoint for
up to fi ve minutes.

10) Select Backlight Display – The display backlight improves
display contrast in low lighting conditions. When the "C" termi-

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

fi lter. When "Change Filter" is displayed, press MENU but-
ton to clear the display and restart the time to the next fi lter
