DANGER
Suitable measures (e.g. safety valves) have to
be taken to ensure that the maximum operating
pressures and maximum and minimum operating
temperatures are not exceeded or undercut.
If necessary, provide an electric sensor attached
to the pipe to protect the surface heating circuit
from unacceptably high temperatures.
The electric sensor attached to the pipe is to
be connected so that the circulation pump is
switched off if the max. permissible operating
temperature (heating water – supply) is exceeded
and the zone valve in the heating circuit return is
closed.
Oventrop offers a suitable sensor attached to the
pipe or actuators (e.g. safety temperature limiter,
item no. 1143000).
