Setup and Adjustments
Thermostat Controller User Interface Keys
The user interface consists of keys on the front cover
(Figure 12). The function of each key is as follows:
•
MODE
key toggles among the system modes
available, as defined by selecting the appropriate
operation sequence in the Installer Configuration
Menu (Off, Heat, Cool, Auto).
•
FAN
key toggles among the fan modes available,
as defined by selecting the appropriate fan menu
options defined in the Installer Configuration Menu
(Low, Med, High, Auto).
•
OVERRIDE
key (commercial models)
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.)
If one of the binary inputs is configured to operate
as a remote override contact, this
OVERRIDE
function is disabled. The
OVERRIDE
key also
allows access to the Installer Configuration Menu.
(See the
Configuring the Thermostat Controller
section.)
•
°C/°F
key (hospitality models) changes the
temperature scale to either Celsius or Fahrenheit
and allows access to the Installer Configuration
Menu. (See the
Configuring the Thermostat
Controller
section.)
Note:
For hospitality models, binary inputs can
override from the unoccupied mode to occupied
mode.
•
UP/DOWN
arrow keys change the configuration
parameters and activate a setpoint adjustment.
