7. Align the tabs on the bottom edge of the mounting
base with the slots on the bottom edge of the
network sensor assembly, and rotate the assembly
onto its mounting base.
Note: On models featuring a screw terminal block, be
certain that the terminal block pins align with the holes
in the terminal block.
8. Use a 1/16 in. (1.5 mm) Allen wrench or
Johnson Controls T-4000-119 Allen-Head
Adjustment Tool to tighten the security screw and
fasten the network sensor assembly to the
mounting base.
Note: Do not overtighten the security screw to avoid
damaging the unit.
9. Use the Metasys® Controller Configuration
Tool (CCT) or Facility Explorer Programmable
Controller Tool (FX-PCT) software to commission
the network sensor. Refer to the Controller Tool
Help (LIT-12011147) for more details.

Setup and Adjustments

Warmer/Cooler Adjustment

Certain models include a warmer/cooler dial designed
to make minor temperature adjustments from the
setpoint. Turning the warmer/cooler dial adjusts the
temperature setpoint up to ±5.0F°/±3.0C°.

Occupancy Override

Some models include an occupancy override push
button on the left side of the network sensor, inline with
the green Light-Emitting Diode (LED). If the green LED
is illuminated, the network sensor is in the occupancy
override mode. If the green LED is not illuminated,
pressing the occupancy override push button activates
the normal-working-hours comfort mode.
Some models include a warmer/cooler dial. If the dial is
rotated, the occupancy override mode is activated.

Network Sensor Addressing

Most network sensors have a default device address of
199 on the SA Bus. For averaging models, the sensor
address must be set on the dual-switch DIP switch
block on the network sensor Printed Wire Board
(PWB).
Averaging models are shipped with both switches set
to ON, resulting in a device address of 203. Device
addresses can be DIP switch set from 200 to 203; see
Figure 3 and Table 1 for more details.
