Thermostat (contact normally closed) for heating resistor regulation. The contact is opened
when the temperature increases.

KTS 011
KTO Thermostat (contact normally open) for regulating filter fans, heat exchangers and air
conditioning units or for triggering signals when the temperature threshold is exceeded.
The contact is closed when the temperature increases.
