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.
Always turn off power at the main power source by removing the fuse, or switching the circuit breaker to the off position before installing,
removing, cleaning, or servicing this thermostat.
Use this thermostat only as described in this manual. Read all of the information in this manual before installing this thermostat.

This is a 24VAC low-voltage thermostat, do not install on voltages higher than 30 vac.
ALL wiring must conform to local and national building and electrical codes and ordinances.
Do not short (jumper) across terminals on the gas valve or at the system control to test installation.
This will damage the thermostat and void the warranty.
Do not switch the system to cool if the temperature is below 50ºF (10ºC). This may damage the air conditioning system.
Replace batteries when the battery icon indicates the low battery message.
Change the Air Filter when the Filter Change Icon begins blinking.
