Digital
Input
Points
Specifies usage of the controller's digital input. Digital Input 1.
DI_WINDOW_CLOSED
Indicates if a window is opened. An open window disables the controller operation. If the contact is closed, the
window is closed.
DI_WINDOW_OPEN
Indicates if a window is opened. An open window disables the controller operation. If the contact is closed, the
window is open.
DI_OCCUPIED_SENSOR
Indicates if the room is occupied. While unoccupied, the controller switches from the occupied operating setpoints to
the standby operating setpoints. If the contact is closed, the space is occupied.
DI_UNOCCUPIED_SENSOR
Indicates if the room is occupied. While unoccupied, the controller switches from the occupied operating setpoints to
the standby operating setpoints. If the contact is closed, the space is unoccupied.
DI_CHANGEOVER_COOL
This selection is for local heat/cool changeover operation for two-pipe units using a switch or local thermostat switch.
When the contact closes, this input indicates that the system can operate in cooling mode. When the contact opens,
this input indicates that the system can operate in heating mode.
DI_CHANGEOVER_HEAT
This selection is for local heat/cool changeover operation for two-pipe units using a switch or local thermostat switch.
When the contact closes, the input indicates that the system can operate in heating mode. When the contact opens,
the input indicates that the system can operate in cooling mode.
DI_MOVEMENT
This selection is used for movement detector configuration where a closed contact indicates movement. Movement
detector is the same as occupancy sensor, but with an additional Hold Time of 15 minutes. This adds a delay to the
occupancy signal such that the space is considered occupied until 15 minutes has elapsed since the last movement
is detected.
DI_NO_MOVEMENT
This selection is used for movement detector configuration where a closed contact indicates no movement.
Movement detector is the same as occupancy sensor, but with an additional Hold Time of 15 minutes. This adds a
delay to the occupancy signal such that the space is considered occupied until 15 minutes has elapsed since the last
movement is detected.
DI_NOT_USED
This setting indicates that the digital input is not used. Use this setting if nothing is connected to the controller to
ensure that spurious signals do not cause the controller to operate incorrectly. The status of this digital input is
reported to the network for use as a free digital input if required. It has no effect on the control algorithm.
