Setup And Adjustments - Johnson Controls NS Series Installation Instructions Manual

IMPORTANT: Failure to adhere to these wiring
details causes the network sensor to function
incorrectly. You will not be able to connect to the
system using the wireless commissioning converter
or the handheld VAV balancing tool, and you will not
be able to expand the system with future offerings.

The large dial on the face of the network sensor
functions in two ways: to increase or decrease the
setpoint temperature, and to change the controller
mode from unoccupied and occupied. When the dial
is rotated slightly, the backlight on the LCD lights up. If
the dial is rotated slightly again, and the controller is in
the unoccupied mode, the controller changes from the
after-normal-working-hours setback mode to the
normal-working-hours comfort mode. To adjust the
setpoint, continue rotating the dial until the current
setpoint is displayed and flashing. Turn the dial
clockwise to increase the setpoint and
counterclockwise to decrease the setpoint. Stop turning
the dial once the desired setpoint is reached. The new
setpoint stops flashing and becomes fixed after a few
seconds.
