Hospitality Applications

Hospitality is a specific kind of occupancy-based control. When the controller is used in a hotel
or dormitory setting, it is typically linked to a keycard switch station or to both an entry door
sensor and an occupancy sensor.
For example, when an occupant enters a room and inserts a key card into the keycard switch
station an occupancy message is sent to linked controllers to power the room. Lights can be
turned ON to a level (occupancy partial-ON) to create a welcoming environment.
For hospitality applications that do not use key cards for room access, an entry door sensor
and occupancy sensor combination can be linked to the controller to confirm occupancy and
therefore proper control. The occupancy sensor is used to monitor occupancy, not to turn
lights OFF. Each time the door is opened and closed and the sensor detects motion, the room
locks into an occupied state. If the door opens and closes, but no motion is detected before
the occupancy auto-OFF timer expires, the room resumes an unoccupied state. If an occupancy
message is sent when the room is in an unoccupied state, the room will lock into an occupied
state until the entry door opens and releases the lock.
Note:
entry door sensor, link the sensor to the controller with the magnet placed next to the
sensor (closed door position). If the magnet is not beside the sensor (open position),
the MC-31 is linked as a window sensor.
Garibaldi Pro software is required to configure all the fade control settings.

Daylight Harvesting Applications

The controller turns the lights ON or OFF based on a set point and the ambient light level in the
room when a photo sensor is linked to the controller. When the controller is configured for
daylight harvesting, the set point is where the light turns ON. The set point to turn the light
OFF is 20% of the sensor's full range greater than the light ON set point.
Note:
Daylight harvesting does not affect the operation of wall switches or occupancy sensors when
the light is ON. If the light is ON, either a switch or occupancy sensor can override with an OFF
action or dim to below the daylighting control value. See

Daylighting Control Override

The open or closed loop daylighting features can be temporarily overridden by enabling the
daylighting manual override parameter. The override has a timer that releases the override
once expired and daylighting control resumes.
If the override is enabled, a switch can turn lights ON and manually set the dimming level.
Garibaldi Pro software is required to configure both the daylighting manual override timer and
daylighting manual override enable parameters.
