Trane THT2184 Temperature Control SPST 265 Open 31 Close

The Trane THT2184 is a temperature control switch for Trane HVAC systems. This is a single-pole, single-throw switch that acts as a critical safety component protecting your equipment from overheating. It is simple to design and measure the ambient air temperature. In this case, the THT2184 opens the electrical circuit when the temperature goes above the specified limit of 265°F, cutting power to the furnace or air handling unit. It protects your HVAC system from damage due to high temperatures. The switch automatically resets at a safe temperature usually about 31°F which reactivates normal functioning.
