cool Multi-stage operation. The display indicates “MS 2” (default for
Multi-stage mode) in the display. The Multi-stage configuration can be
toggled to “SS1”, or “HP1” by pressing the up or down key. In Multi-stage

6) Selects time format display 12hours or 24hours
7)Select Compressor Lockout COMP OFF or ON
Selecting COMP ON will cause the thermostat to wait 4 minutes before
turning on the compressor if the heating and cooling system loses power. It
will also wait 4 minutes minimum between cooling and heating cycles. This is
intended to help protect the compressor 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 lockout feature is
already present in their system. When the thermostat compressor time delay
occurs it will flash the setpoint for about four minutes.

The Fan switch should normally be located in the AUTO
position. The Fan will be turned on along with normal
operation of your system. In a normal gas or oil furnace, the
Fan will be turned on by your furnace after its warm-up
delay. For electric heat, air conditioning, and heat pump operation, the Fan
will turn on with the system. To run the Fan on continuously, slide the Fan
switch to the ON position.
Energy Monitor
■
The Energy monitor feature measures and stores the
amount of time the heating and air conditioning system
operates. Usage can be display for Today (since 12

easy viewing in the dark.
When any key is pressed the display is illuminated.
The display will remain illuminated for 8 seconds after the last key is pressed.
This allows the light to stay on if you need to operate several keys.

Low Battery Warning
Your thermostat has a two-stage lower battery warning system. When the
batteries are first detected to be weak, the first stage low battery warning is
indicated by “BATT” flashing on the LCD display. At your
earliest convenience, you need to replace the batteries with
2 new AAA alkaline batteries.
When the batteries become too weak for normal operation,
the thermostat enters the second stage low battery warning
which shuts down the thermostat. In this condition, “BATT”
flashes alone on the display, and the thermostat will turn your
system Off. Your system will remain shut-off until the
batteries are replaced.
NOTE:
The thermostat will still keep the current Set Temperature and Filter
run time in memory until new batteries are installed. After confirming that
new batteries have been inserted, the thermostat will return to normal
operation.
Error Mode
If the thermostat is unable to control your system due to an
unexpected battery problem, the thermostat will enter Error
Mode. In this condition, the thermostat flashes
“E1”,“E2”,”E3”or”E4”on the LCD display, and shuts off your

new AAA alkaline batteries, even if you have recently replaced
them. Move the battery out, and then hold any key to release
the rest energy. Then place the battery again. You will need
