Trane SRL300 Manual Reset Thermostat

Product Description

The TRANE SRL300 is a manual reset thermostat designed for use in HVAC systems where automatic reset is not appropriate. This safety device monitors temperature conditions and trips when a preset limit is exceeded, requiring a manual reset before the system can resume operation. It is typically installed by licensed HVAC technicians as part of a high-limit or safety-limit circuit in heating and cooling equipment. The manual reset design ensures that a technician must physically inspect and clear the fault condition before the system restarts, preventing repeated cycling through an unsafe state.

The SRL300 is suited for residential and light commercial HVAC applications where limit control and safety interlock functions are required. It is installed within the equipment cabinet as part of the control circuit, providing a safeguard against overtemperature conditions that could damage components or create a hazard. HVAC technicians servicing Trane equipment will recognize this as an OEM-style replacement component for limit or safety thermostat applications.
