Thermostat Operation Overview
Thermostat User Interface Keys
The TEC26x7-2 Series Thermostat user interface
consists of three keys on the front cover (as illustrated
in Figure 19). The function of each key is as follows:
•
OVERRIDE
key overrides the unoccupied mode to
occupied at the local user interface for the
specified TOccTime. (TOccTime is defined by
selecting the appropriate time period in the Installer
Configuration Menu.) The
OVERRIDE
key also
allows access to the Installer Configuration Menu.
See the
Configuring the TEC26x7-2 Series
Thermostat
section.
Note:
If one of the binary inputs is configured to
operate as a remote override contact, this
OVERRIDE
key is disabled.
•
UP/DOWN
arrow keys change the configuration
parameters and activate a setpoint adjustment.
Backlit Liquid Crystal Display (LCD)
The TEC26x7-2 Series Thermostats include 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)
Two LEDs are included to call for heat or call for
cooling:
•
The
HEAT
LED is on when heating or reheat is on.
•
The
COOL
LED is on when cooling is on.
Status Display Menu
The Status Display Menu is displayed during normal
thermostat operation. This menu continuously scrolls
through the following parameters:
•
Room Temperature
•
System Mode
•
Occupancy Status
(Occupied/Unoccupied/Override)
•
Applicable Alarms (The backlight lights up as an
alarm condition is displayed.)
Note:
An option is available within the Installer
Configuration Menu to lock out the scrolling display and
show only the
Room Temperature
parameter.
