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 tem-
perature reach the program setpoint at the time you specify.
Heating will start 5 minutes early for every 1° of temperature
required to reach setpoint. Cooling allows more time per
degree because it takes longer to reach temperature.

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 thermostat setpoint will change to
70° at 6:35 AM.

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 - Al-

lows 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.
