Description
The Bosch HVAC 87229638580 Temperature Limit Sensor tracks thermal levels within the heat exchanger and sends accurate readings to the boiler’s processing unit to prevent unsafe temperature rise. A negative temperature coefficient thermistor element responds to heat fluctuations by altering its electrical resistance, prompting the board to cut burner output before essential thresholds are breached across HVAC systems. Fitted directly onto the heat exchanger in gas boilers without requiring pipe alterations or specialist tools, it acts as a safeguard against overheating conditions. Accurate thermal detection reduces unexpected shutdowns, maintains steady heating output and extends the overall operational duration of the unit.
