Safety instructions for working on the system
Working on the system
■Where gas is used as the fuel, close the main gas
shut-off valve and safeguard it against unintentional
reopening.
■Isolate the system from the power supply, e.g. by
removing the separate fuse or by means of a mains
isolator, and check that it is no longer live.
■Safeguard the system against reconnection.
■Wear suitable personal protective equipment when
carrying out any work.
Danger
Hot surfaces can cause burns.
■Before maintenance and service work, switch
OFF the appliance and let it cool down.
■Never touch hot surfaces on the boiler, burner,
flue system or pipework.
!Please note
Electronic assemblies can be damaged by elec-
trostatic discharge.
Prior to commencing work, touch earthed
objects such as heating or water pipes to dis-
charge static loads.
Repair work
!Please note
Repairing components that fulfil a safety func-
tion can compromise the safe operation of the
system.
Replace faulty components only with genuine
Viessmann spare parts.

Auxiliary components, spare and wearing parts
!Please note
Spare and wearing parts that have not been tes-
ted together with the system can compromise its
function. Installing non-authorised components
and making non-approved modifications or con-
versions can compromise safety and may inva-
lidate our warranty.
For replacements, use only original spare parts
supplied or approved by Viessmann.
Safety instructions for operating the system
If you smell gas
Danger
Escaping gas can lead to explosions which may
result in serious injury.
■Do not smoke. Prevent naked flames and
sparks. Never switch lights or electrical appli-
ances on or off.
■Close the gas shut-off valve.
■Open windows and doors.
■Evacuate any people from the danger zone.
■Notify your gas or electricity supply utility from
outside the building.
■Have the power supply to the building shut off
from a safe place (outside the building).
If you smell flue gas
Danger
Flue gas can lead to life threatening poisoning.
■Shut down the heating system.
■Ventilate the installation site.
■Close doors to living spaces to prevent flue
gases from spreading.
What to do if water escapes from the appliance
Danger
If water escapes from the appliance there is a
risk of electrocution.
Switch OFF the heating system at the external
isolator (e.g. fuse box, domestic distribution
board).
Danger
If water escapes from the appliance there is a
risk of scalding.
Never touch hot heating water.
Condensate
Danger
Contact with condensate can be harmful to
health.
Never let condensate touch your skin or eyes
and do not swallow it.
Flue systems and combustion air
Ensure that flue systems are clear and cannot be
sealed, for instance due to accumulation of conden-
sate or other causes. Ensure an adequate supply of
combustion air.
Inform system users that subsequent modifications to
the building characteristics are not permissible (e.g.
cable/pipework routing, cladding or partitions).
Danger
Leaking or blocked flue systems, or an inade-
quate supply of combustion air can cause life
threatening poisoning from carbon monoxide in
the flue gas.
Ensure the flue system is in good working order.
Vents for supplying combustion air must be non-
closable.
Extractors
Operating appliances that extract air to the outside
(extractor hoods, extractors, air conditioning units, etc.)
can create negative pressure. If the boiler is operated
at the same time, this can lead to reverse flow of the
flue gas.
Danger
The simultaneous operation of the boiler and
appliances that extract air to the outside can
result in life threatening poisoning due to
reverse flow of the flue gas.
Fit an interlock circuit or take suitable steps to
ensure an adequate supply of combustion air.

Product information
The energy meter determines by means of 3 current
sensors (standard delivery) whether there is an excess
of on-site generated power. This information is passed
on via the connection to the output control module. In a
continuously variable feed, the output control module
then feeds the excess power generated on site to an
immersion heater in the DHW cylinder, e.g. the Vitocell
100-B, type CVE.

1. Danger
When subject to insolation, PV modules can
generate life threatening voltages. Contact
with live parts (e.g. terminals) can lead to
burns and electric shock, even if the PV
modules are not connected.
■First disconnect the inverter from the AC
grid (AC side of the inverter).
■Then disconnect the DC isolator from the
DC grid (DC side of the inverter).
■If required, cover PV modules with light-
proof films or fabrics.
■Observe VDEW guidelines and technical
connection requirements of the grid opera-
tor.
2. Install energy meter on a mounting rail in the distri-
bution panel, see fig. 1.

Regulations
■Connect the power supply and implement all safety
measures (e.g. RCD circuit) in accordance with
IEC 60364-4-41, the connection requirements of
your local power supply utility, and VDE or national
regulations.
■Disconnect the system by means of a device that
simultaneously separates all non-earthed conductors
with at least 3 mm contact separation.
In addition, we recommend installing an AC/DC-sen-
sitive RCD (RCD class B ) for DC (fault) cur-
rents that can occur with energy efficient equipment.
Danger
Incorrect core assignment can result in serious
injury and damage to the appliance.
Never interchange cores "L" and "N".

Possible causes:
■Electrical connection between energy
meter and output control module is faulty.
■Electrical connection of current sensors is
faulty.
■Check all electrical connections.
■Check orientation of current sensors,
see page 8.
■Switch power supply OFF and ON
again.
■Immersion heater could not be switched
on:
–Electrical connection between output
control module and immersion heater is
faulty.
–The set DHW temperature has been
reached.
■Check the electrical connection.
■Ensure heat transfer.
■During the initialisation process, the ener-
gy meter establishes the maximum out-
put of the immersion heater. If the maxi-
mum output fluctuates by more than
500 W, the initialisation process was un-
successful.
Restore the energy meter to its delivered
condition, see page 14.
