PRODUCT DESCRIPTION
The W7753A Unit Ventilator Controller is a Free Topology
Transceiver (FTT) L
ON
M
ARK
® Compliant Unit Vent controller
in the Excel 10 family product line.
This controller can be used to monitor/control HVAC
equipment, lighting, and other miscellaneous loads in a
distributed network. The controller is field-mounted to the
equipment that it controls, and the controller wiring is attached
to the screw terminals located on the controller (see Fig. 1).
The W7753A Controller communicates via the 78 kilobaud
Echelon
®
LonWorks
®
E-Bus Network.
Allowable input/output connections consist of wall module
points plus two additional resistive sensor inputs, two voltage/
current inputs, four digital inputs and eight digital Triac
outputs.
For the W7753A, any hardware driven by the Triac outputs
must have a minimum current draw, when energized, of
25 mA and a maximum current draw of 500 mA.
