5.2.8 Water supply
D ATTENTION!
Risk of damage caused by poor water quality.
Too high a proportion of suspended solids and magnetite
along with the incorrect water hardness can damage the
generation unit or shorten its service life.
A
Check the water quality regularly.
B
The water quality must comply with the specifications of
the applicable standards and Directives
(e.g. in Germany, VDI Regulation 2035).
B
The heating system water must be free from mechanical
impurities.
B
The hardness of the water must be < 0.11 °dH.
B
Conductivity < 100 µS/cm.
B
PH value > 8.2 and < 9.0.
5.2.9 Condensate drain
For the system to operate, the building must have a
condensate drain, which must comply with the following
requirements:
B
The condensate drain must be depressurised.
B
The inner diameter of the condensate drain must not be
reduced.
B
A neutralization device is recommended for each system
to collect condensate containing oil.
B
The siphon must be made of corrosion-resistant, acid-
resistant material (e.g. plastic or stainless steel).

connection to the electricity supply that must comply with
the following requirements:
B
The specifications and technical connection conditions
of the energy provider must be taken into consideration
(e.g. electricity meter).
B
The start-up power and cable lengths must be taken into
account when calculating the cable cross-sections.
B
The supply voltage must meet the system specifications.
D
“12.1 Technical data” (page 37).
5.2.11 Mobile communications network
Remote monitoring via the modem requires access to the
mobile communications network. The modem must be
accessible. The position of the modem has an influence on
the reception quality.
The reception quality may be improved as required by
means of the following accessory (optionally available):
B
External antenna (distance max. 15 m)
B
Patch cable (max. 100 m long)
