2.1 Intended use
Contact thermostat with sensor head for limiting the temperature of
Fonterra surface heating units in combination with control stations.
2.2 Operating mode
In case of a fault, the safety contact thermostat switches off the circulation pump and therefore prevents the Fonterra surface heating from
overheating. To avoid undesired activation, set the temperature at the
safety contact thermostat 10 C° above the desired supply temperature
(factory setting 60 °C).
