Operating Principle:
The thermostat operates with an “On-Off” contact switching system: when the temperature rises, one contact opens (terminals 1-2) and another closes (terminals 1-4).
Plastic “limit clips” prevent accidental adjustments and allow users to restrict the temperature setting range.
Applications:
-
Domestic heating systems (boiler control, radiator circuits)
