Honeywell W7620 - Manual (Page 5)

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
closed contacts. The analog outputs are 0-10 Vdc.
The ‘I7660 is a platinum RTD (Resistive Temperature
Device) that is placed in the zone for temperature readings.
are available with or without an integral setpoint
adjustment dial or an occupant override push button with
status LED (Figure 2). The push button allows setting
the heating or cooliig system to an occupied mode when
the control system is in an unoccupied mode. Also, it
can be used to initiate a continuous unoccupied period.
The LED indicates the override status. These zone sensors
are furnished with an RJ11 connector for local operation
of an S7610 POT (Portable Operator’s Terminal). (See
the T7660A-D Space Temperature Sensors Information
and Installation sheet, Form 63-4219, for more details.)
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 to the controller through a
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 on the
network. See the S7610 Zone Control POT Guide, Form
63-4225, for information on operation. See Figure 3.
