UCM maximum capacities for Tracker model WSHP

UCM maximum capacities for Tracker
model WSHP
The Tracker model WSHP controller can control and monitor specific
types and numbers of Trane unit control modules (UCMs) as specified in
this topic. The supported UCMs are as follows:
Space Comfort Controllers (SCCs): the primary controller options are
•
the Tracer ZN510, ZN511, and ZN524. Other controllers are limited
to Voyager rooftops with a Tracer LCI-V, Precedent rooftops with Reli-
aTel controls and a Tracer LCI-R, and Tracer ZN517 unitary control-
lers
• Tracer loop controller (TLC)
• Tracer MP503 I/O module
Table 3 shows the maximum number of each UCM type that can be linked
to each Tracker controller model. Any combination of the specified UCMs
may be used in aggregate if they do not exceed the maximum. (For
example: As the table shows, a fully loaded Tracker WSHP controller can
control 100 SCC devices, 1 Tracer loop controller (TLC), and 4 Tracer
MP503 I/O modules.)
Note:
See repeater information, "Requirements for repeaters on
Comm5 communication links" on page 37.
