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).
