Honeywell W7620 Heat Pump User Manual


 
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.
Sensors
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.
