Safety thermostat

Every heater has got a number of safety thermostats
interrupting the elcetric circuit, at high water temperatures
(95°C). These safety thermostats cannot be reset
but after a drecrease of the temperature by 20°C.
Subsequently, the regulating thermostat will be checked:
if it has been adjusted at a high temperature, the
thermostat will probably be broken and must be replaced.
