Installing/Changing
A low battery icon will light on the thermostat display when the batteries are within a
week or two of being exhausted. The thermostat is designed to use standard AA-size 1.5 volt
batteries. If the batteries are depleted, the heating/cooling system will go to the OFF state.
Replacing Batteries
To open the thermostat, remove the security screw
(#2 Phillips or #2 security screw). Using both hands, press
the two push-tabs on the bottom of the thermostat housing
with your thumbs, while pulling the front of the thermostat
away from the base.
The thermostat operates with 4 AA batteries.
Batteries are paired, one set on top
of the other.

Introduction.
This two-part wireless thermostat system is designed to provide precision temperature control
without the installation headaches and expense of wiring. Powered by four AA batteries, the
thermostat will operate for approximately 1 year, and can be mounted in any suitable location
that will ensure good temperature control. A large LCD display provides the user with current
space temperature, set point temperature, time, program interval and other system status
information. The second part of the system is the receiver. The receiver interfaces with the
desired HVAC equipment and communicates with its thermostat using unlicensed 900MHz
radio frequency energy. At the time of installation, the thermostat is linked to one or more
receivers. A thermostat and receiver that have been linked will not interfere with or be affected
by any other thermostat or receiver in adjacent rooms, apartments or neighboring homes.

Buttons.
A four-button cluster is located on the front of the thermostat.
These buttons are used in adjusting fan operation, changing
the set point temperature up or down and changing the
operating mode of the thermostat. To the right are the
display items that are changed by the four buttons in
normal operation.
Note that the UP, DOWN and HEAT/COOL
buttons are also used in setting the clock and programming the thermostat and linking to
receiver(s). This will be covered in the following sections of the manual.
The four buttons located on the left side of the thermostat control the display of the
temperature in either Fahrenheit or Celsius, programming and clock set up. These buttons
also allow manual or program control.
• F/C – Toggles between the Fahrenheit and Celsius displays
• Program set-up button
• Run – Sets the program or manual mode of operation
• Clock set-up button

Backlight.
A single button on the right side of the thermostat activates the display backlight. The backlight
will illuminate the display after the last button is pressed. Backlighting takes significant energy
from the batteries and should be used sparingly. Frequent use of the backlight function will
noticeably reduce battery life.
