1) Select Temporary Hold Time - The thermostat 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 disables the function
Example:
1. You have selected 3:00 hours for the Temporary Hold time
period.
2. With the thermostat set to HEAT or COOL, press HOLD
for approximately five 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 preference.
The thermostat will maintain this temperature setting for 3
hours with “HOLD” blinking to remind you it is in Tempo-
rary Hold. After 3 hours the thermostat will go back to the
program temperature and “HOLD” will no longer blink or
display.
2) Select FA or SL (Fast or Slow) Heating Cycle Rate - The
FA setting is frequently used for gas, oil or electric heat. The
SL setting produces a longer heating cycle which is normally
for hot water or steam (hydronic) systems. Both settings
produce very accurate temperature control and can be set to
your personal preference. FA cycles the system just under
1°F and the SL setting cycles at approximately 1.5°F.
3) Select backlit display - The display backlight improves
display contrast in low lighting conditions. Selecting backlight
ON will keep the light on for a short period of time after any
key is pressed. Selecting OFF will keep the light off.
4) 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 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 temperature.

5) 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 000 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. Changing the time in the menu also resets
the timer.
6) Select Compressor Lockout LOC OFF or ON - Selecting
LOC 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 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 feature is already
present in their system. When the compressor time delay
occurs it will flash the (snowflake icon) for about five minutes
then turn on the compressor.
7) Select Temperature Display Adjustment 4 LO to 4 HI -
Allows you to adjust the room temperature display 4° higher
or lower. Your thermostat was accurately calibrated at the
factory but you have the option to change the display tem-
perature to match your previous thermostat.
8) Select F° or C° Readout - Changes the display readout to
Centigrade or Fahrenheit as required.
