Thermostat Operation Overview
Thermostat User Interface Keys
The T600HPx-3 thermostat user interface consists of
five keys on the front cover (as illustrated in Figure 8).
The function of each key is as follows:
•Use the YES/SCROLL key to:
- confirm menu selections and to advance to the
next menu item
- stop the Status Display Menu from scrolling
and to manually scroll to the next parameter on
the menu
Note: When the thermostat is left unattended for
45 seconds, the thermostat display resumes
scrolling.
•Use the NO key to decline a parameter change and
to advance to the next menu item.
•Use the MENU key to:
- access the Main User Menu or exit the menu
- access the Installer Configuration Menu or to
exit the menu (See the Configuring the
T600HPx-3 Thermostat section.)
•Use the UP/DOWN arrow keys to change the
configuration parameters and to activate a setpoint
adjustment.
Backlit Liquid Crystal Display (LCD)
The T600HPx-3 thermostat includes a 2-line,
8-character backlit display. Low-level backlighting is
present during normal operation, and it brightens when
any user interface key is pressed. The backlight returns
to low level when the thermostat is left unattended for
45 seconds.
Light-Emitting Diodes (LEDs)
Three LEDs are included to indicate the fan status, call
for heat, or call for cooling:
•The FAN LED is on when the fan is on.
•The AUX HEAT LED is on when auxiliary heat is
on
•The HEAT-PUMP LED is on when the heat-pump
compressor is on.
