Thermostats
There are four thermostats : The first is of 47°C and the second of 60°C, (for
automatic programs) are fitted to the fan casing.
The third of 115°C (resets automatically) operates at 115°C switching out
one of the heaters if the temperature rises excessively. The fourth thermo-
stat, also fitted to the heater casing, operates at 150°C and provides protec-
tion against dangerous overheating. It must be manually reset.
The manual overheating protection breaks the contact to the starter relay,
which means that the machine stops completely when there is overheating.
