Truma Ultraheat sensor FY1
Remote temperature sensor to work with a Truma 3002 fire and Truma Ultraheat
This Truma Ultraheat Sensor is the official remote sensor used to improve temperature regulation on Ultraheat electric heaters in caravans and motorhomes.
When fitted, it bypasses the basic sensor inside the Ultraheat wall switch and instead measures temperature at a better reference point in the living area, helping to avoid overheating near the fire and giving a more even room temperature
