2 Product information
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 circula-
tion 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).
NOTICE!
Make sure that the permissible maximum floor temperature
is not exceeded in the vicinity of the heating pipes.
