Do not mix battery types, use either all lithium or all alkaline. Do
not put new batteries in with an old pair. If you are replacing
batteries, replace them all.
When four (4) batteries are currently installed, remove either the
top two end-to-end pair or the side-by-side pair and replace them.
Next, remove the other pair and replace. This keeps power to the
thermostat at all times, maintaining your clock and program
settings.
If two batteries are currently installed, install two new batteries in
the empty battery holders, noting the + and – polarity. Next,
remove the old batteries. This replacement scheme also allows
the thermostat to continue running without losing any
programmed information or clock setting.
If replacing batteries with a different type (i.e., replacing Lithium
with Alkaline or Alkaline with Lithium) — Remove old batteries
and wait for the front display to go blank. Install new batteries,
reset the time and programs.
FOUR-BUTTON / HOTEL CONFIGURATION
The T9000 can be ordered in a four or seven button configuration.
Typically in hotel applications, users do not need access to
programming or clock functions. Buttons for those functions are
therefore not provided in the hotel model. The four-button
control cluster consists of FAN, HEAT/COOL, UP and DOWN.
