Room thermostat Jung RTR230, supply 230 V, normally open contact (RTR230)

The Jung RTR230 room thermostat is designed for reliable on/off temperature control in residential and commercial interiors. Powered from a 230 V supply, this wall-mounted thermostat uses a normally open contact configuration to switch heating or ventilation circuits when room temperature reaches the setpoint. Its conventional wiring and compact design make it suitable for integration into existing electrical installations where simple, manual temperature control is required.

Advantages

The thermostat provides straightforward temperature regulation through a mechanical switching action, ensuring clear on/off control without complex electronics. Its 230 V supply compatibility allows direct connection to common mains systems, and the normally open contact is suitable for devices or control circuits that require closing on a rise in temperature. The unit’s compact, wall-mounted form supports easy replacement or new installation in standard flush-mounted boxes.

How to use

Install the Jung RTR230 in a location representative of the room temperature, away from direct sunlight, drafts or heat sources to ensure accurate sensing. Connect the thermostat to the 230 V supply and the controlled circuit following local electrical regulations and wiring diagrams. Set the desired temperature setpoint using the adjustment control; the normally open contact will close or open to switch the attached heating or ventilation device based on the measured room temperature.

Recommendations

For reliable operation, verify that the installation complies with applicable electrical safety standards and that the controlled load is compatible with a mechanical normally open contact at mains voltage. Avoid placing the thermostat near radiators, windows with strong sunlight, or ventilation outlets to prevent incorrect temperature readings.
