Notes:
1.
The FA setting is used to produce shorter Heating/Cooling cycles. The SL setting produces a longer Heating/Cooling cycle.
Both settings produce very accurate temperature control and can be set to your personal preference. FA cycles the system
at a 0.5ºF (0.5ºC) differential, and SL cycles the system at 1.5ºF (1.5ºC).
2.
When operated from batteries only, the LCD display backlight will be illuminated less than 5 seconds after each button
pressed, options (2) & (3) will operate the same when terminal “C” is not connected.
3.
The thermostat will display the Filter Alarm 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 12 months in 1 month increments. Selection of 00 WILL CANCEL THIS FEATURE.
When Filter Alarm is displayed, you can clear it by pressing the
▲
and
▼
buttons. This resets the timer and starts
counting the days until the next filter change.
4.
Select compressor lockout delay 0,1,2,3,4,5 To protect the compressor from short cycling, you can select compressor
off-time cycle between 0 to 5 minutes. When the thermostat compressor time delay occurs, the Cool On or Heat On display
will flash during compressor lockout.
5.
Select Intelligence 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 set-point at the time you specify. Heating will
start 5 minutes early for every 1° of temperature required to reach set-point.
