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.

Table 3. Tracker controller model WSHP UCM capacities

Tracker model	UCM type	Maximum
		UCMs
WSHP	SCC*	100
	TLC**	1
	Tracer MP503 I/O module	4
	Total maximum UCMs supported	105

* SCCS supported by Tracker are limited to Tracer ZN510, ZN511,and ZN524; Voyager rooftops; Precedent rooftops with ReliaTel controls; and Tracer ZN517.

** The TLC is mandatory and must be present to enable SCC compressor operation.

IMPORTANT

SCC compressor operation will be enabled only when a TLC is commu- nicating with the Tracker panel.
