Interfaces
BACnet IP – System interface
• BTL Certification
• BACnet Standard ISO 16484-5:2010
• Optional AMEV certificate
Modbus TCP – System interface
Analog/Digital
• Central fault message via relay with volt-free contact
• Temperature or output target value above 0 ... 10-V
input
Further possible interfaces and protocols are e.g.:
• Modbus ASCII, RTU
• Mbus
• BACnet MS/TP
• Profibus
• LON
• KNX
• SNMP
• oBIX or
• Analogue/digital inputs and outputs
All data points in the system can be provided via the
interface. The available data points depend on the
controlled devices and control functions. In the standard
version, 20 data points are given. A higher amount of
data points is available upon request.
Via the interface, all messages and faults are
transmitted.

Flue system

Flue system behind CHP
The flue gas line must be pressure-tight and condensate-
resistant and suitable for flue gas temperatures to
650 °C.
Inspection apertures must be provided in accordance
with DIN V 18160-5. The flue gases from CHP modules in
buildings must be dissipated through suitable, airtight
pipework above the roof in accordance with the German
Firing Installations Order.
It is only permitted for flue gases to enter chimneys or
flues if it can be proven that the flue gases can be
dissipated effectively, even while combustion
equipment is connected.
This flue can be routed within buildings in ducts and
channels that are ventilated from the rear. Outside
buildings, the flue can be routed on the façade and up to
the top of the roof. If one or more flue gas silencers are
planned, the condensate drains must be individually
equipped with the correct seal siphons or condensate
valves.
Bosch supplies system flues which are tailored to CHP
modules. For CHP modules, a state-of-the-art flue
system suitable for pressure class H1 (test pressure
5000 Pa, permissible leakage rate < 0.006 l/s m
be installed. The pressure class is specified by the
manufacturer of the CHP flue gas line as part of the
certificate of conformity.
The tightness tests are to be repeated at regular
intervals. In the case of conversions and visible leaks,
the tightness tests must be carried out immediately.
