Ventilation Control Module
(VCM - Optional 3U218 used with Traq Fresh
Air Measurement and/ or CO2 Sensor)
The Ventilation Control Module (VCM) is located in the
filter section of the unit and is linked to the unit's UCM
network. Using a “velocity pressure” sensing ring located
in the outside air section, allows the VCM to monitor and
control the quantity of outside air entering the unit to a
minimum airflow setpoint.
An optional temperature sensor can be connected to the
VCM which enables it to control a field installed outside air
preheater.
If the unit has a VCM, an optional CO
2
sensor can be
connected to the unit to the unit for CO
2
reset control. CO
2
reset permits the unit to reduce the amount of outside air
entering the unit from the Design OA (Design OA
damper%) to the DCV OA (DCV Minimum damper%) based
on the space or return CO
2
level.The following table lists
the possible airflow range per unit size.
The velocity pressure transducer/solenoid assembly is
illustrated below. Refer to the “Traq Sensor Sequence of
Operation” section for VCM operation.
Generic Building Automation System
Module
(GBAS - Optional 1U51 used with non-Trane
building control systems; 0-5 or 0-10 VDC)
The Generic Building Automation System (GBAS) module
allows a non-Trane building control system to
communicate with the rooftop unit and accepts external
setpoints in form of analog inputs for cooling, heating,
supply air pressure, and a binary Input for demand limit.
Refer to the “Field Installed ControlWiring” section for the
input wiring to the GBAS module and the various desired
setpoints with the corresponding DC voltage inputs for
both VAV and CV applications.
