6. If the controller requires Offboard Air Modules,
install them now following the appropriate
Installation Instructions (see
Product Numbers
).
7. Connect the point wiring (see
Wiring Diagram
s).
CAUTION
DO Wiring – Each DO provides a
Normally Open (NO) terminal and a
Common (C) terminal.
To reduce noise and the potential
for ground loops, both connections
of a 24 Vac load must be wired
directly to the DO terminal on the
controller board.
CAUTION
The fume hood flow module, the
FHC, any 0 to 10 Vdc actuator used
by the LCM, and the LCM cannot
share a single power trunk.
The preferred configuration for
shared power trunks is to use one
trunk for the FFM and FHC and
another trunk for the actuator(s) and
LCM.
8. For each Fast Acting Lab Electronic Actuator,
verify that the switches are set as shown in

Switch Settings for the Fast Acting Lab Electronic
Actuator.
CAUTION
This actuator requires a maximum
of 20 VA, 24 Vac source.
DO NOT connect any other non-
isolated devices to the transformer
that powers the electronic actuator
or the hot water valve actuator.
9. Plug the room temperature sensor cable into
the RTS port.
10. Connect the power trunk. DO NOT apply
power to the controller without first consulting
the specialist.
CAUTION
It is important that the neutral that
supplies the TEC must be earth
grounded at the source of the 24
Vac power.
Possible erratic equipment
operation or damage if neutral is not
grounded.
The installation is complete.
