Installing/Changing
A low-battery icon will light on the thermostat display when the batteries are close to
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, 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 remote temperature control.
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 and 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.
