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

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.

manually raised by 3°F or more above the actual tem-
perature with the
