Override function
— An override function is available for
units operating in occupied/unoccupied mode under the
control of an external timeclock or an energy management
system. A contact closure from the timeclock or energy
management system shorts the NSB and C terminal on the
Deluxe D controller signaling an unoccupied mode.
For units with the unit-mounted thermostat, pressing
override switch (located under control access door) will
override the unoccupied mode and allow the occupied
mode of operation to continue for a period of two hours.
The units with the remote wall-mounted thermostat
require a digital thermostat with the override function. In
unoccupied mode, an accessory relay is energized on the
Deluxe D controller. The NO/NC contacts of the relay can
be used as appropriate input to the digital thermostat to
signal occupied/unoccupied mode. The thermostat selects
cooling/heating set points based on occupied/unoccupied
mode.
PremierLink™ controller is compatible with the Carrier
Comfort Network
®
(CCN) and other building automation
systems (BAS). This control is designed to allow users the
access and ability to change factory-defined settings thus
expanding the function of the standard unit.
LONMark
®
compliant controller contains the factory-
loaded Aquazone™ water source heat pump application
for an interoperable control solution.
WSHP Open multiple protocol controller is a proac-
tive controller capable of communicating BACnet™,
Modbus
®
*, N2, and LON (with a separate card) protocols.
The controller is designed to allow users the access and
ability to change and configure multiple settings and fea-
tures including indoor air quality (IAQ), waterside econo-
mizer controls, etc.
