Safety instructions for working on the system
Working on the system
■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.
!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.

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.

Intended use
The device serves to control heating systems with
solar DHW heating and solar central heating backup.
The appliance is intended solely for installation and
operation in sealed unvented systems compliant to
EN 12976 and EN 12977, with due attention paid to
the associated installation, service and operating
instructions as well as the details in the datasheet.
It is designed exclusively for heating the solar circuit.
Commercial or industrial use for a purpose other than
heating the solar circuit shall be deemed inappropriate.
Intended use presupposes that a permanent installa-
tion in conjunction with permissible components
designed for this purpose has been carried out.
All other use is deemed inappropriate. Any resulting
losses are excluded from the manufacturer's liability.
Any usage beyond this must be approved by the man-
ufacturer in each individual case.
Intended use also includes the adherence to mainte-
nance and inspection intervals.
Product information
The Vitosolic 100 is an electronic temperature differen-
tial controller for dual mode DHW heating with solar

Danger
Incorrect wiring can lead to serious injury from
electrical current and result in appliance dam-
age.
■Route LV leads < 42 V and cables
> 42 V/120 V~/230 V~ separately.
■Only strip the minimum of insulation from
cables, as close to the terminals as possible,
and bundle tightly to the corresponding termi-
nals.
■Secure cables with cable ties.
■When connecting external switching contacts and
on-site components, observe the insulation require-
ments of IEC/EN 60335-1.
!Please note
Electronic assemblies can be damaged by static
loads.
Prior to commencing work, touch an earthed
object such as a heating or water pipe to dis-
charge static load.

High limit safety cut-out
A high limit safety cut-out in the consumer is required
when less than 40 litres cylinder volume is available
per m2 absorber area. This installation safely prevents
temperatures in excess of 95 °C in the consumer.
Note
Observe the max. collector area that can be connected
in relation to the Vitocell 100.
Installation
Install the sensor of the high limit safety cut-out inside
the cylinder cap (Vitocell 300 accessory).

Isolators for non-earthed conductors
■Install an isolator in the power cable to provide
omnipolar separation from the mains for all active
conductors, corresponding to overvoltage category
III (3 mm) for full isolation. This isolator must be fitted
in the permanent electrical installation, in line with
the installation requirements.
■We additionally recommend installing an AC/DC-
sensitive RCD, type B , for DC (fault) currents
that can occur with energy efficient equipment.
Power supply for accessories and external compo-
nents
■For accessories and external components that will
not be connected to the control unit, we recommend
making the power connection to the same fuse, or at
the very least in-phase with the control unit.
■Connection to the same MCB/fuse provides addi-
tional safety when the power is switched off.
Observe the power consumption of the connected
consumers.
Danger
Incorrectly executed electrical installations can
result in injuries from electrical current and in
appliance damage.
Connect the power supply and implement all
safety measures (e.g. RCD circuit) in accord-
ance with the following regulations:
■IEC 60364-4-41
■VDE regulations
■Technical connection requirements specified
by the local power supply utility
■Protect the power cable on site with a
fuse/MCB of up to 4 A.
Danger
The absence of component earthing can lead to
serious injury from electric current if an electrical
fault occurs.
The appliance and pipework must be connected
to the equipotential bonding of the building.
Danger
Incorrect core allocation can result in serious
injury and damage to the appliance.
Never interchange cores "L" (brown) and "N"
(blue).

1. Check whether all electrical connections have been
correctly made.
2. Check that the high limit safety cut-out (if required)
is connected.
3. Switch ON the power; the solar control unit then
enters an initialising phase.
The solar control unit is now in automatic mode.
4. Check which type of solar circuit pump is connected
and set parameter "RPM" accordingly (see pages 7
and 14).
