Setup and Adjustments
Overview
Figure 8 shows the front cover, including features used
for setting up and adjusting the thermostat controller.
User Interface Keys
The user interface consists of keys on the front cover
(as illustrated in Figure 8). 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 (for example Off, Heat, Cool, Auto).
•
FAN
key toggles between ON and AUTO for fan
control. ON energizes the fan all the time and
AUTO operates the fan only on a call for heating or
cooling, for both occupied and unoccupied periods.
•
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 Thermostat Controller
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.
Light-Emitting Diodes (LEDs)
Three System Activity LEDs are included to indicate
the status and actions of the thermostat controller:
•
The
FAN
LED is on when the fan is on.
•
The
HEAT
LED is on when heating or reheat is on.
•
The
COOL
LED is on when cooling is on.
