Occupancy Modes
The UVC is provided with four occupancy modes: Occupied,
Manual Command and Network Occupancy Sensor network
variables, along with the Unoccupied and Tenant Override binary
inputs are ignored when another network variable or binary input
NOTE: The Occupancy Manual Command is provided as
a way for a network connection to manually force
the UVC into a particular occupancy mode. The
Occupancy Manual Command can override the tenant
override feature. For example, if the network uses the
Occupancy Manual Command to force the unit into
unoccupied mode, then the tenant override switch
does not operate as expected. Therefore, Daikin
strongly recommends using the Occupancy Sensor
Input to control occupancy modes over a network and
only using the Occupancy Manual Command if there is
reason to ensure tenant override does not occur.
When the MicroTech UVC is connected to a
wall sensor and building network, the building
management system must write to the Occupancy
Sensor, NOT the Occupancy Schedule for the wall
sensor’s occupancy override feature to function.
Occupied Mode
The Occupied mode is the typical day time mode of UVC
operation. During Occupied mode the UVC uses the occupied
heating and cooling setpoints, the OAD operates normally,
ServiceTools software.
Unoccupied Mode
The Unoccupied occupancy mode is the typical night time or
weekend mode of UVC operation. During Unoccupied mode
the UVC uses the unoccupied heating and cooling setpoints,
the OAD remains closed, and the IAF cycles as needed for
to remain on (at low speed) in unoccupied mode with the LUI
keypad or ServiceTools software.
Standby Mode
The Standby mode is a special purpose daytime mode of UVC
operation. During Standby mode the UVC uses the standby
heating and cooling setpoints, the OAD remains closed, and by
default the IAF remains on. The standby setpoints are closer to
the occupied setpoints versus the unoccupied setpoints. This
allows the space to achieve the desired occupied condition
more quickly than when coming out of the Unoccupied mode.
Bypass Mode
The Bypass mode (also called Tenant Override) is the equivalent
of a temporary occupied mode. Once the Bypass mode is
default). During the bypass mode, the UVC uses the occupied
heating and cooling setpoints, the OAD operates normally, and
by default the IAF remains on.
