1.4 CE

label

The CE label indicates compliance of the VRC 430f con-
troller with the fundamental requirements of the rele-
vant directives.

2 Safety

The VRC 430f may only be installed by an approved
heating engineer. This person is also responsible for the
proper installation and initial start-up.

H

Caution!

Risk of being scalded by hot water! When the
target temperature is above 60 °C, there is a
risk of scalding at the hot water taps. Young
children and elderly persons are particularly at
risk, even at lower temperatures.
Risk to persons should be excluded through the
selection of an appropriate target temperature
(see Section 4.7.4).

Caution!

Risk of being scalded by hot water!If your heat-
ing engineer has activated the anti-legionella
option for the hot water cylinder, the tempera-
ture of the hot water at the draw-off points
may exceed 60 °C at specific times.
Find out from your heating engineer whether
the legionella protection has been activated and
if so, on what day and at what time.
