3. Appliance description
The appliance provides the required amount of dHW at the
preferred temperature at the draw-off points. This occurs with-
in the output limits of the appliance. Heating water is distrib-
uted to the connected radiators.
4. Cleaning, care and
maintenance
A damp cloth is sufficient for cleaning the casing. Never use
abrasive or corrosive cleaning agents.
The heat exchanger requires regular cleaning, depending on
water quality. Have the appliance cleaned by a qualified con-
tractor after no more than 2 years. The qualified contractor
will then determine the intervals at which it should be cleaned
thereafter.
5. Troubleshooting
Problem
Cause
Remedy
dHW and radiators do
not heat up.
The central pump is not
working.
Check whether the cen-
tral pump is running.
The heating system is
not working.
Check whether the
heating system is free
from faults.
If you cannot remedy the fault, contact your qualified contrac-
tor. To facilitate and speed up your request, provide the num-
ber from the type plate (000000-0000-000000).

INSTALLATION
6. Safety
Only a qualified contractor should carry out installation, com-
missioning, maintenance and repair of the appliance.
6.1 General safety instructions
We guarantee trouble-free function and operational reliability
only if original accessories and spare parts intended for the
appliance are used.
6.2 Instructions, standards and regulations
Note
Observe all applicable national and regional regula-
tions and instructions.
7. Appliance description
For dHW heating, cold water flows to the plate heat exchanger.
The "thermo fluid system" measuring system detects the dHW
demand. Some of the heating water from the heating water
flow is channelled over the heat exchanger to heat the dHW
to the required temperature. dHW from the cold water con-
nection is channelled through the heat exchanger and heated
as required. dHW flows from the heat exchanger to the dHW
outlet. The maximum water volume can be limited with the
flow limiter in the dHW outlet.
A cold water outlet supplies the draw-off points from a cold
water distributor inside the appliance.
A water hammer arrestor is fitted for pressure protection.
Heating water from the heat generator is distributed by the
appliance to the radiators via the dirt filter.
Note
See chapter "Add-on options" for descriptions of the
add-on options.
