Introduction
The T9000 Wireless Temperature Control is a two-part
wireless thermostat system designed to provide precision
temperature control without the installation labor and expense
of wiring. Powered by AA batteries, the thermostat can operate
continuously for approximately 18 months, and can be mounted
in any suitable location that will provide good temperature
control. A large LCD display (Figure 1) provides the user
with current room temperature, set point temperature, time,
program interval, and other system status information. In hotel
applications, programming, clock set up buttons and associated
display information are typically not displayed. The second part
of the T9000 system is called a Remote Control Node or “RCN”.
An RCN interfaces with specific desired HVAC equipment,
and communicates with its thermostat using unlicensed 900
MHz, radio frequency energy. At the time of installation, the
T9000 thermostat is linked to one or more RCN controls. The
thermostat and RCN that have been linked will not interfere
with, or be affected by, any other thermostat or RCN in adjacent
rooms, apartments, or neighboring homes.
Batteries
Installing/Changing
A low battery icon will light on the thermostat
display when the batteries are within approximately one week
of being exhausted. The T9000 is designed to use standard
