Easy DDC Controller
SC 9100 is a preconfigured, controller, designed
for the control of heating, ventilation or air
conditioning installations. The SC-9100 is a
unique controller with multiple standard
applications, which can be chosen from the
controller’s memory during installation.
Parameters can be adapted to fit the exact
requirements. Other application programs
may be created on quantity order.
The display shows in clear text the inputs,
outputs and main control information. The
controller is protected to avoid unauthorized use
(password). The SC 9100 is a full stand-alone
controller, and may be connected to a
communication bus as part of a JOHNSON
CONTROLS Supervisory System.
The room command module SC-9180 may be
connected to the SC-9100 to provide remote set
point and real time clock.

SC-9100-MK: Panel mount kit
Hardware: 4 analog inputs (2 x 0/10 V or
NTC, 2 x NTC)
2 digital inputs (potential free
3 analog outputs (0/10 V)
2 triacs outputs (24 VAC, 0,5 A)

SC-9100 contains PI modules, ON/OFF,
calculations (e.g. set point reset by outside
tempera-ture), logic controls (e.g. frost
The SC-9100 applications are divided into
categories and are stored in memory, available
when it is first installed.
You will find all the available applications fully
described in the “Application Note” bulletins.
Which can be found in the “Application Manual”.
Sensors and Actuators
The sensors and actuators, which are to be used in
connection with the SC-9100, are defined in the
“Application Note” bulletins.
• TS -91
• RS -91
Valves and Actuators:
• M- 91 and M-92
• Frost protection 270XT
• Room command module SC-9180
screwdriver, insulation stripping tool.
Before connecting or disconnecting any wires,
ensure that all power supplies have been switched
off to prevent equipment damage and avoid
electrical shock. Separate extra low voltage (safe)
wiring from power line voltage wiring.
The 24 V supply must be stable and not shared
with other switched inductive loads.
These controllers are designed for use as an
operating control. When an operating control failure
would result in personal injury and/or loss of
property, it is the responsibility of the installer to
wire a separate back-up control (a freeze
protection thermostat for instance) in order not to
use the SC-9100 both as an operating and a safety
