TEMPERATURE ACCURACY
Full temperature accuracy will be realized only after the thermostat has
been installed and powered for at least one (1) hour.
THERMOSTAT AND SENSOR CALIBRATION
Simply press and hold the FAN button for 10 seconds and adjust with
the
c
or
d
button.
POWER FAILURES
Your thermostat employs the latest in solid state electronic technology.
One of the unique features of your thermostat is that no battery is
required to maintain your selected setpoints 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.
REMOTE SENSOR (OPTION)
RS1 – RS2 – RS+V
The thermostat is designed to accept the electronic remote sensor, which
will allow you to locate your thermostat in an area away from view. Indoor
and outdoor sensors are available separately.
CLOCK TERMINALS (OPTION) CLK1 – CLK2
Your thermostat is equipped with a dry contact closure input. By
connecting to any relay-based controller or clock timer, the thermostat
can be alternated between the day and night (setback) temperature
setpoints automatically.
Upon initial power up of the thermostat, or after a power failure, the ther-
mostat will check the clock terminals and apply the day (open
contact) or night (closed contact) temperature setpoints accordingly.
USER CONTROLS

and
d
to switch between Celsius (˚C) and
Fahrenheit (˚F) temperature display.
COMMUNICATIONS (OPTION) X1 - X2
The thermostat is designed to accept any of the Net/X family of remote
communications controllers (available separately). The controllers allow
full functionality and control from a distance of up to 1000 feet away.
FAN
k
The fan will come on automatically when the system is operating, but
there is no indication of this on the display. To select continuous fan
operation, press the FAN button and the display will show
k
. This is
recommended for electronic air cleaners and continuous
ventilation requirements.

To turn off the heating or cooling system, press the MODE button until the
word OFF appears on the LCD. It will remain displayed until the mode is
changed. The OFF mode prevents the system from being energized.
Avoid
using the OFF mode during extremely cold weather to prevent
damage to the equipment from freezing.
AUTO CHANGEOVER
You may set the thermostat to switch automatically from heating to cool-
ing mode by pressing the MODE button until the word AUTO and both the
heating
i
and cooling

energize the heating or cooling system based on the temperatures estab-
lished for both modes.
TEMPORARY TEMPERATURE OVERRIDE
WITH KEYPAD LOCKED
(The keypad may be locked to prevent tampering by selecting the ON
position of DIP switch #2.)
If the keypad is locked to prevent tampering you may temporarily adjust
the setpoint by ±3°F of the programmed day setpoint. Press the

or
d
button to raise or lower the setpoint for a 1 or 3 hour period, depending
on DIP switch settings.

Your new electronic digital thermostat has been designed to provide
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 instructions 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 or heating is currently on. The six buttons on the
front of the unit allow complete control of your equipment.
You may select different heating and cooling setpoints for the system to
maintain, e.g., 70° in heating and 75° in cooling. Raising or lowering the
setpoints in heating or cooling is as simple as pushing a button. In addi-
tion, 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.
