Navigating
You can quickly step through to a specific item you
want to change by pressing the HEAT/COOL button until
the item you want to change is flashing. When that item
is flashing, use the UP or DOWN button to adjust.
Exiting Program Mode
Pressing the program button at any time will exit out
of the programming mode, save your changes to memory
and return to normal thermostat operation.
Run Button
Program / Manual Operation
The RUN button toggles the thermostat between
manual operating mode and program operating mode.
When in the program mode your thermostat responds
to the times and temperatures programmed.
Figure 6. Program Mode Display
Figure 6 shows the thermostat running in the program
mode. One of the four periods, in this case “Day”, is
displayed, letting you know which period of the day it
is in. When in the manual mode as shown in Figure 7,
the period of the day is not displayed. Instead the word
“Hold” will be displayed above the Set point temperature,
indicating the thermostat is holding that temperature.
In manual mode, you can adjust the desired
temperature using the UP and DOWN buttons, and
the thermostat will maintain the temperature until you
change it again.

Changing Temperature While Running
A Program
You can always change the temperature up or
down while a program is running. However, when the
program moves to the next period, the program set point
temperature for that period will take effect. For instance,
assume the current program period is Evening, with a
programmed temperature of 70°, and the next period,
Night, is programmed for 65°, scheduled to start at 11:00
PM. If during the Evening time period you desired the
space to be warmer, you could press the UP button to
raise the temperature set point. The thermostat will hold
that temperature until the next program period, at which
point the temperature will adjust to the programmed
temperature set point for that period. In this case the
Night period is set for 11:00 PM and 65°.
Installing and Removing Nodes
A T9000 thermostat and remote control node will
not operate as a system until they are linked together
through the installation process. The linking process binds
one or more control nodes to a thermostat so that they
will communicate with each other as a control system.
Up to eight nodes can be linked to a single thermostat.
Until linked, the control node will not operate. Once
linked, a control mode will only respond to its specific
thermostat. The thermostat and RCN that have been
linked will not interfere with, or be affected by, any other
thermostat or RCN in the adjacent rooms, apartments,
or neighboring homes. Linking information is stored
in non-volatile memory – it is not necessary to Re-link
the thermostat and RCN if the thermostat batteries are
removed, or after a power outage.
Installing Nodes
If multiple installation teams are installing and linking
thermostats at the same time, coordinate the activity
to avoid the possibility of installers simultaneously
attempting to perform the linking process. Because
this is an RF system, installers in nearby rooms/areas
where it is possible RF overlap could exist, run the risk
of interfering with each other. Installation and linking
activity going on around a system already installed will
not interfere with it.
Refer to Figure 8 for inside thermostat buttons and
jumper locations and functions.
