Cause Remedy

The ON/OFF switch is switched off. Switch the ON/OFF switch ON.

The solar control unit MCB has responded (mains volt-

age is present, display is not illuminated).

Inform your local heating contractor.

Collector limit temperature or set cylinder temperature

has been reached.

Wait until the relevant temperature has fallen below its

respective limit.

The solar control unit is in "Manual mode". Select "Auto" as follows:

1. Press .

2. Press until "Manual mode" is displayed.

3. Press OK to confirm.

4. Press until "Relay 1" etc. is displayed.

5. Press OK to confirm.

6. Press the / keys for "Auto".

7. Press OK to confirm.

8. Press until "Main menu" is displayed.

There is no DHW available

Cause Remedy

The solar control unit is faulty. Inform your local heating contractor.

Collector temperature is too high; safety shutdown by

the solar control unit.

Wait until the collector temperature has dropped.

The set cylinder temperature (set DHW temperature)

has been set too low.

Inform your local heating contractor.

The solar circuit pump is faulty. Inform your local heating contractor.

The DHW cylinder is not being reheated:

The operating and time program is incorrectly set at the

boiler control unit.

Enable DHW heating.

Operating instructions of the boiler control unit

The display is dark

Cause Remedy

Power failure The solar control unit automatically returns to operation

once the power supply has been restored.

The power distribution MCB (main domestic MCB) has

responded (no mains voltage is present).

Check the MCB and inform your heating contractor if

necessary.

The display illumination flashes

Cause Remedy

Solar thermal system fault. Call up the fault (see following chapter) and contact

your local heating contractor if necessary.

What to do if...

The solar thermal system does not start

5608 437 GB

If any faults have occurred in your solar thermal sys-

tem, the display illumination flashes and "Fault"

appears on the standard display.

DHW cylinder (if installed)

Standards DIN 1988-8 and EN 806 specify that main-

tenance and cleaning should be carried out no later

than 2 years after commissioning and as required

thereafter.

Only a qualified heating contractor should clean the

inside of a DHW cylinder and the DHW connections.

If any water treatment equipment (e.g. a sluice or

injection system) is installed in the cold water supply of

the DHW cylinder, ensure this is refilled in good time.

In this connection, observe the manufacturer's instruc-

tions.

In addition for Vitocell 100:

We recommend that the correct function of the sacrifi-

cial anode is checked annually by your heating con-

tractor.

The function of the sacrificial anode can be checked

without interrupting the system operation. The heating

contractor will check the earth current with an anode

tester.

Safety valve (DHW cylinder)

The function of the safety valve must be checked

every six months by the user or a contractor through

venting (see valve manufacturer's instructions). The

valve seat may become contaminated.

Water may drip from the safety valve during a heat-up

process. The outlet is open to the atmosphere and

must not be closed off.

Potable water filter (if installed)

To maintain high hygienic standards, proceed as fol-

lows:

■Replace filter element on non-back flushing filters

every six months (visual inspection every

two months).

■On back flushing filters, back flush every

two months.

Damaged cables / lines

If there is damage to the connecting cables or lines of

the appliance or externally installed accessories, these

must be replaced with special cables or lines. Only use

Viessmann cables / lines as replacement. For this,

notify your qualified contractor.
