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 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.
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 nor-
mally 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 approxi-
mately 1.5 F.
3) Select backlit display - The display backlight improves
display contrast in low lighting conditions. Selecting back-
light 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, cooling 15
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 requires 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
temperature to match your previous thermostat.
8) Select F or C Readout - Changes the display readout to
Centigrade or Fahrenheit as required.
9) Select Stage Fast (ON or OFF) - When selected ON, the
second stage starts as soon as the setpoint temperature is
manually raised 3 F in heat or lowered 3 F in cool from
room temperature. When selected OFF, the second stage
will delay approximately 15 minutes before starting.
