EXCEL 10 W7750A,B,C CONSTANT VOLUME AHU CONTROLLER

	Like the W7751 VAV Box Controller, the W7750 Controller can		Form No.	Title
	monitor a space-mounted occupancy sensor, and a door/
	window contact. These inputs affect the operational mode of		74-2956	Excel 10 W7750A,B,C Controller Specification
	the controller (see Table 5 for a list of all possible modes of			Data
	operation).		74-2697	Excel 10 T7770A,B,C,D,E,F,G Wall Module
	The W7750 Controller allows other controllers in the system to
				Specification Data
	use the W7750s physical inputs and outputs. A digital input
	and an analog input can be configured to read switch states		74-3097	T7560A,B Digital Wall Module Specification
	and voltage sensor values, respectively, and send them out			Data
	over the LONWORKS Bus network. The Q7750A Zone
	Manager can use these values in custom control strategies.		74-2950	Excel 10 Q7750A, Zone Manager Specification
	Additionally, two of the W7750 digital outputs are available for			Data
	control program use. These outputs only respond to signals
	sent over the network, and are not controlled by the W7750		74-2952	Excel 10 Q7751A,B Router Specification Data
	internal control algorithms.		74-2954	Excel 10 Q7752A Serial Interface Specification

	Organization of Manual		95-7620	T7560A,B Digital Wall Module Installation
	This manual is divided into three basic parts: the Introduction,			Instructions
	the Application Steps, and the Appendices that provide		95-7509	Excel 10 Q7750A Zone Manager Installation
	supporting information. The Introduction and Application
	Steps 1 through 5 provide the information needed to make			Instructions
	accurate material ordering decisions. Application Step 6 and		95-7510	Excel 10 Q7751A,B Router Installation
	the Appendices include configuration engineering that can be
	started using Excel E-Vision PC Software after the devices			Instructions
	and accessories are ordered. Application Step 7 is		95-7511	Excel 10 Q7752A Serial Interface Installation
