RT-SVX24J-EN
heating operation is limited to either 50% or 100%.
Demand limit can be initiated by a toggle switch closure,
a time clock, or an ICS
TM
control output. These contacts
must be rated for 12 ma @ 24 VDC minimum.
Outside Air Sensor—BAYSENS016*
This device senses the outdoor air temperature and sends
this information in the form of an analog input to the RTM.
It's factory installed on units with an economizer, but can
be field provided/installed and used for informational
purposes on units without an economizer. Refer to the
appropriate illustrations in
Figure 58, p. 88 Figure 59, p. 89
for the proper connection terminals in the unit control
panel. Refer to
Table 34, p. 85
for Temperature vs.
Resistance coefficient.
Generic Building Automation System
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,
demand limiting, and supply air pressure parameters.
Refer to
Figure 61, p. 91
&
Table 35, p. 92
for the input
wiring to the GBAS module and the various desired
setpoints with the corresponding DC voltage inputs for
VAV, SZVAV and CV applications.
