F.1.2. Occupancy connections /
Remote connections / Etc
(Cont.)
For connecting Remote Smoke Detectors or Fire
Control Panels to this control DO NOT break
the 24VAC to the thermostat or from the power
supply transformer. Either could cause an
undersirable operating condition that would not
shut the unit down in the event of an emergency
situation. See the instructions for the type of
control board this unit is equipped with.
Using cutters or a small screw driver, break
the edge of the board between the to terminals
marked with “OCC”. Use 3/16” blade
connector, and a minimum of 18AWG wire
to connect to a Normally Closed Dry Contact
Relay or Switch. Do not connect multiple control
boards to the same dry contact relay or switch.
REM – Remote Shutdown Control. This feature
allows the unit to be turned off remotely ignoring
the thermostat calls for cooling or heat. Locate
the terminals at the left side of the board mark
“REM”. See Figure
F.1.2. – A: Occupancy and
Remote Connetions
for reference.
Using cutters or a small screw driver, break
the edge of the board between the to terminals
marked with “REM”. Use 3/16” blade
connector, and a minimum of 18AWG wire
to connect to a Normally Closed Dry Contact
Relay or Switch. Do not connect multiple control
boards to the same dry contact relay or switch.
F.1.3. Connecting a Smoke Detector
F.1.3.1. Core Command Connection
SD – Remote Smoke Detection. This feature
allows for the proper shutdown of the controls in
the event of an emergency situation. Locate the
terminals at the left side of the board mark “SD”.
See
Figure F.1.2. – A: Occupancy and Remote
Connetions
for reference.
Using cutters or a small screw driver, break
the edge of the board between the to terminals
marked with “SD”. Use 3/16” blade connector,
and a minimum of 18AWG wire to connect
to a Normally Closed Dry Contact Relay, or
in common Fire Control Panels and Smoke
Detectors, the Auxilary Connections for C and
NC. See the instructions for the remote devices.
Do not connect multiple control boards to the
same dry contact relay.
F.1.3.2. DDC Control Connection
In the air-filter section or on the side
economizer, locate the 12-pin Molex jumper
plug with the long Red, short Yellow and
Orange wire loops; see
Figure F.1.3.2. - A
for
reference. Cut the Red wire loop and connect
these to a minimum of 18AWG wire that will be
connected to a Normally Closed Dry Contact
Relay, or in common Fire Control Panels and
Smoke Detectors, the Auxilary Connections for
C and NC. See the instructions for the remote
devices. Do not connect multiple control
boards to the same dry contact relay.
F.1.4. Building Management / Control
Connections using DDC –
In an application where a third party building
management / controls are in use or will be
incorporated, units with the integral Rooftop
Unit Controller (RTU-C) are communication
compatible with the system that supports
the BACnet Application Specific Controller
device profile, LonMark Space Comfort
Controller functional profile, or LonMark
Discharge Air Controller functional profile. This
is accomplished with a field installed BACnet
or LonMark communication module. Refer to
the Clear control/DDC manual for more detail;
Manufacturer Part number: 92-103249-01.
