Description
The Aaon P85440 Limit Switch 230 ENC 7.00 is a temperature safety control used to monitor internal operating conditions and protect the system from overheating in HVAC systems. It is to open the control circuit when temperatures rise to approximately 230F stopping heating or compressor operation to prevent damage to essential components. Once the temperature drops to a safe range, the breaker resets and allows normal operation to resume. Mounted in air handling units or packaged rooftop systems, it is typically positioned near the heat exchanger or discharge air path.
