SEE REVERSE FOR INSTALLATION INSTRUCTIONS
Your new digital thermostat has been designed to pro-
vide accurate control and display of room temperature.
In addition, it also will display all relevant information
pertaining to your system.
The clearly marked buttons and informative display
make it extremely easy to understand and simple to
use.
Please take a few moments to read the brief instruc-
tions and familiarize yourself with the various functions
in order to obtain maximum benefit from this truly
unique electronic control.
GENERAL INFORMATION
The thermostat normally displays room temperature,
mode of operation and whether cooling is currently on.
The six buttons on the front of the unit allow complete
control of the equipment.
Raising or lowering the setpoints in cooling is as simple
as pushing a button. In addition, you may choose to
display the temperature in °F or °C.
The thermostat also allows you to select continuous fan
operation (useful when using an air cleaner) or have the
fan come on with the equipment.
POWER FAILURES
Your thermostat employs the latest developments in
solid state electronic technology.
One of the unique features of your thermostat is that
no battery is required to maintain your selected set-
points in the event of a power loss as the memory is
unaffected by power failures of any duration.
When power is restored, the thermostat will continue
operating as if the power had never been off.
TEMPERATURE ACCURACY
Full temperature accuracy will be realized only after
the thermostat has been installed and powered for at
least one hour.
