The W7622 output board has a selection of outputs
depending on the model number. One output board of
any type can be added to the W7620 Zone Controller.
The W7622 drives any output (for heat, cool, etc.), either
digital or analog. Function depends upon application. The
relay outputs have both normally open and normally

The S7610 POT is a hand-held &vice that provides a
means to set, test, and monitor point and parameter values.
The POT utilizes the RS-485 CNAP nehvork for
communication and connects
cable to an RJ11 jack at the T7660 Zone Temperature
Sensor, or to an RJ11 jack inside the controller case.
The POT can communicate to any controller
network. See the S7610 Zone Control POT Guide, Form
