Truma Ultraheat Temperature Limiter 30030-65200

The Truma Ultraheat Temperature Limiter Device (Lock-Out Safety Overrun Thermostat) is an essential safety component for Truma space heaters. Compatible with Ultraheat models S3004, S5004, S3002, S5002, and S55T (Part No. 30030-65200), it prevents overheating by locking out the system when temperature limits are exceeded.

When replacing this limiter, it’s often necessary to address the root cause—a faulty temperature control device (thermostat). For optimal performance, replace it at the same time using the correct part code: TRS 30030-65100.
