deemed to be impermissible incorrect use. This
includes:
●Application areas not listed under "Application".
●Use of operating fluids that do not correspond to
the manufacturer's specifications.
●Use outside the permissible technical operating
limits.
●Use in areas at risk of explosion.
●Use outdoors.
●Bypassing of safety equipment.
●Operation as an emergency generator.
●Use only for heat generation if power is not drawn
off simultaneously.
●Siting in the same room/air ratio as a boiler
system with atmospheric burner or an NH3
refrigeration unit.

5.3 Remote monitoring with
TeleControl LAN
Every Vitobloc 200 CHP unit is equipped as standard with
the TeleControl LAN module. It is used for remote
monitoring of the CHP unit and provides the operating
data via the LAN/internet.
The only requirement is a network connection with free
access to the internet at the system.
Note:
The Telecontrol LAN gets its network settings via
DHCP. The Internet connection must be able to assign
the IP address, subnet mask, standard gateway and
nameserver via DHCP. The Telecontrol LAN sends
UDP packets via port 3003 to the server "ess-
telecontrol.de". The Internet connection must allow UDP
packets over port 3003 direction "ess-telecontrol.de".
There are no incoming packets.
When the CHP unit is switched on, the TeleControl LAN is
recognised automatically and is operational immediately.
After commissioning, you should contact the CHP Service
department at Viessmann Landsberg (Tel. [phone] /
9279-60) to check whether the data from the
corresponding CHP unit is being received at the
Viessmann data server.
How to install and use the client software for calling up
operating data is described in the TeleControl GPRS /
TeleControl LAN operating instructions.
After registering as the operator, it is also possible to
access the CHP unit operating data directly via the
internet.

The CHP TeleControl app for use with iOS and Android
mobile devices is also available for download.
5.4 Requirements for optimal
operation
●Faults and consequential losses resulting from
prohibited operating conditions are not covered
by the warranty or any service contract.
●Always avoid shutting down on full load, as this
would subject the components to the highest
mechanical loads.
●Avoid cyclical on-off operation and provide a
buffer if necessary. The ratio of hours run to
starts relative to average hours run must be
greater than 3, i.e. after 3000 hours run, the unit
should have started less than 1000 times. The
greater the ratio of hours run to starts, the
better.
●Ensure a constant, adequate heating water flow
rate.
●The combined heat and power (CHP) unit must
be protected against silting from the existing
heating system. It is recommended that you
install a dirt catcher and a dirt separator in the
return line to the CHP unit.
●Include an optional heat meter in the return
temperature raising facility to detect the amount
of heat generated.
●Ensure gas flow pressure of 20 mbar to 50
mbar.
●Ensure an adequate supply of fresh air and that
extract air is discharged securely.
●The condensate line must be checked regularly
blockages and sufficient water seal. Hydraulic
seals must be executed, so that the water level
can be checked and filled.
●Regular servicing and maintenance by qualified
personnel in accordance with the manufacturer's
maintenance instructions. We recommend a
service contract.
●The batteries must be disconnected by the
manufacturer's technicians in the event of
prolonged idle periods or decommissioning of
the CHP unit. In the case of idle periods lasting
longer than 12 weeks, the CHP unit must be
preserved by the manufacturer's technicians.

Control level 1 includes all default screens.
Subject to the number of components to be controlled,
one or more default screens are possible. They are
selected using the arrow buttons "more ►" and "more
◄".
All default screens are available with the "All OK check
mark" or with current operating data.
Control level 2 includes the operating level.
Touch the relevant component field in the default
screen to open the respective operating screen for the
component.
In the operating level, additional operating and
measurement data can be called up and a limited
number of settings can be made.
Control level 3 is the setting level. It is reserved for
trained service personnel with password authorisation.
