INSTALLER/CONFIGURATION MENU
5) System Switch 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 (Off Heat), and Cool only (Cool Off).
6) Energy Management Recovery – (this step is skipped if
configured to be non-programmable).
Energy Management Recovery (E) On 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: 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 set-
point will change to 70° at 6:35 AM. Cooling allows
more time per degree, because it takes longer to reach
temperature.
7, 8 & 9) Cycle Rate Selection – The factory default setting
for Heat is fast cycle (FA Cr), which cycles heat at
approximately 0.6°F. If you prefer slow cycle, press the
or key to change to SL. Heat will cycle at approxi-
mately 1.2°F. For Cool the default setting is fast cycle
(FA Cr), which cycles cool at approximately 1.2°F. If you
prefer slow cycle, press the
or key to change to SL,
cool will cycle at approximately 1.7°F. Cycle rate selec-
tion for EMER and Aux is only for HP 1 or HP 2 systems.
10) Select Compressor Lockout CL OFF or ON – Selecting
CL ON will cause the thermostat to wait 5 minutes be-
tween cooling cycles. This is intended to help protect the
compressor from short cycling. Some newer compres-
sors 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.
11) Select Backlight Display – The display backlight
improves display contrast in low lighting conditions.
When the C terminal is powered, selecting backlight (dL
ON) will turn the light on continuously. Selecting backlight
OFF will turn the light on momentarily after any key is
pressed. When the C terminal is not powered, this
selection has no effect.
12) 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 cali-
brated at the factory, but you have the option to change
the display temperature to match your previous thermo-
stat. The current or adjusted room temperature will be
displayed on the left side of the display.
13) Select F° or C° Readout – Changes the display readout
to Centigrade or Fahrenheit as required.
14) Select Audio Prompting (Beeper) On or Off – Default
setting is On (On b) if you wish to turn off the beeper
select Off b.
15) Heat Temperature Limit Range – This feature adjusts
the highest setpoint temperature for heat. The default
setting is 99°F. It can be changed between 62°F and
98°F by pressing the
or key. The "temperature
limit" icon will be displayed to the left of your setpoint
temperature when using this feature. The "temperature
limit" icon will flash if an attempt is made to adjust the
temperature beyond the range selected.
16) Cool Temperature Limit Range – This feature adjusts
the lowest 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. The "temperature
limit" icon will be displayed to the left of your setpoint
temperature when using this feature. The "temperature
limit" icon will flash if an attempt is made to adjust the
temperature beyond the range selected.
17) Keypad Lockout – This step allows you to select the
type of lockout or limited range security required. If no
lockout or limited range security is required, press
to
advance the menu.
Three security settings are available in this menu item.
Use the
or keys to select the lockout desired.
Lockout selections are:
"Keypad Lockout and L" = Total Lockout. Total Lockout
locks all keys.
"Keypad Lockout and P" = Partial Lockout. Partial Lock-
out allows only the
or keys to operate within your
set temperature limits.
"Temperature Limit/Keypad Lockout" prevents
changing the temperature limits in the Configuration
Menu.
18) Keypad Lockout Combination Number Selection
Display will read "OFF" "Keypad Lockout".
Skip this step and continue through the configuration

select will start in 10 seconds. The system button will
remain active for 10 seconds to allow setting Heat, Off,
Cool or Auto.
19 & 20) Select Fast Second Stage ON or OFF – In the run
mode, with the fast Heat feature enabled (FA Heat On), if
the Heat setpoint temperature is manually raised by 3°F
(2°C) or more above the actual temperature using
the
second stage will energize immediately. With FA OFF,
second stage will not energize until the setpoint tempera-
ture is 1°F or more above actual temperature for more
than ten minutes. The Fast Cool feature (FA Cool)
provides the same controls when the setpoint tempera-
ture is lowered.
21) Select Filter Replacement Run Time – The thermostat
will display "Change Filter" after a set time of blower
operation. This is a reminder to change or clean your air
filter. This time can be set from 25 to 1975 hours in 25
hour increments. A selection of OFF will cancel this
feature. When "Change Filter" is displayed, you can
clear it by pressing Clean Display. In a typical application,
200 hours of run time is approximately 30 days.
22) Select Humidifier Pad Replacement Run Time – The
