Johnson Controls Temperature Controls Are Used As Operating Controls For Heating or Refrigeration Applications.
Temperature Controls are available in Single Pole or Four-Wire Two-Circuit controls. Four-Wire Two-Circuit Temperature Controls incorporate a vapor-charged sensing element. The 4-wire, 2-circuit contact block contains two isolated sets of contacts that closes the auxiliary contact closes when the main contact opens. Snap-acting contacts operated by temperature sensing element. Single Pole Temperature Controls are operating controls that feature ranges to cover most applications. Controls may open or close a circuit on temperature increase as required. Heavy-gauge low-profile stainless steel element cup provides added durability.
