4 DDC KIT The Zone Controller
THE ZONE CONTROLLER
The Digital Direct Control board also known as DDC
and shown in Figure #1 is used in most congure to
order applications.
It is BACnet® native which makes it exible and easy
to integrate into existing Building Automation
Systems (BAS). The controller provides the end user
with a superior amount of information when
compared to a traditional thermostat.
The controller is programmed in the factory with
software versions that suit the different application
for the models offered by Bosch. User settings such
as the time and schedules can be preprogrammed or
also change during the installation of the product.
Digital Outputs: Five digital outputs relay contacts
rated at 1A resistive @ 24VAC; congured as dry
contact, normally open.
Universal Inputs: 8 inputs. Inputs 1 and 2 are
congurable for 0-5VDC, 10K ohm thermistor, or
dry contact; inputs 3 and 4 support thermistor or
dry contact only; inputs 5 and 6 support
thermistor, dry contact, or LogiStat.
Standard Communication Ports:
Comm Port: 3-pin port congurable for ARC156
(BACnet-over- ARC156) or EIA485communications (BACnet MS/TP, Modbus
RTU, orN2).
Rnet Port: 4-pin port for interface with remote
mounted BACview6 or RS sensors
Local Access Port: For local communication with a
laptop computer running WebCTRL or for
communication with a BACview6.
Status Indication: Visual (LED) status of network
communication, running, errors, power, and all
digital outputs
