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.
