monitoring of the CHP unit and provides the operating
data via LAN/internet.
The only requirement is a network connection with free
access to the internet at the system.
Note:
The TeleControl LAN obtains its network settings via
DHCP. The internet connection must be able to assign an
IP address, subnet mask, default gateway and name
server via DHCP.
The TeleControl LAN transmits UDP packets via port 3003
to the "ess-telecontrol.de" server. The internet connection
must permit UDP packets via port 3003 to "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 separate "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.

TeleControl" app can also be downloaded.
5.4 Requirements for optimum
operation
●Faults and consequential losses resulting from
prohibited operating conditions are not covered
by the warranty or any service contract.
●Always avoid shutting down at full load, as this
would subject the components to the highest
mechanical loads.
●Avoid cyclical on/off operation and provide a
buffer store if necessary. The ratio of hours run
to starts relative to average hours run must be
greater than 3, i.e. after 3000 hours runtime, 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 CHP unit must be protected from sludge
from the existing heating system. It is
recommended that a dirt trap and a dirt separator
be installed in the return to the CHP unit
●Include an optional heat meter in the return
temperature raising facility to detect the amount
of heat generated.
●Ensure a gas flow pressure of 30 mbar to
50 mbar.
●Ensure an adequate supply of fresh air and that
extract air is discharged securely.
●The condensate drain pipe must be checked
regularly for obstructions and to see if there is a
sufficient hydraulic seal. Hydraulic seals must be
designed so that the water level can be checked
and topped up.
●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.
