Gira room temperature controller 230 V normally open 247400

Maintaining a consistent room temperature without constant manual adjustment can be a challenge. The Gira Room Temperature Controller 247400 solves this by automatically regulating heating systems based on the ambient temperature. This flush-mounted controller uses a bimetal sensor with thermal feedback to switch a 10 A resistive load, making it suitable for controlling electric heaters, thermal actuators, or pumps in residential and commercial settings.

Who is it for

This controller is ideal for electricians, HVAC installers, and homeowners who need a reliable, non-programmable room thermostat for heating control. It fits standard Gira switch ranges including System 55, E2, Event, Esprit, and ClassiX, ensuring seamless integration with existing installations.
