NOTE:
Use 24
V
AC
(only) on triac
outputs (BO1–BO6 with SCs)!
NOTE:
See the
KMC Conquest Controller
Application Guide
for information
about switched commons (SC),
using VDC power, and other issues.
NOTE:
Connect the
STE-9xxx
(or
STE-6010/6014/6017
with
no ventilation control) sensor
to the Room Sensor port
using a max. of 150 feet
of Ethernet patch cable.
CAUTION:
Do NOT connect 24 VAC
to the analog outputs
(UO7–UO10 and GNDs)!
NOTE:
For
MS/TP
models, turn the End Of
Line switch ON at both physical ends
of the MS/TP network. Connect the
cable shield to earth ground at only
one point.
NOTE:
For
Ethernet
models, connect the
controller to the network with a
standard Ethernet patch cord.
NOTE
: Analog
inputs
accept 1K or 10K
sensors, 0–12 VDC, or 4–20 mA.
NOTE:
For more
wiring examples
, see the
wiring diagrams that are part of the
application library in KMC Connect,
Converge, or TotalControl. Early
models shown in the drawings had
different terminal locations. Follow
the terminal
labels
(not location).
