Working Mechanism

  • Johnson Controls penn thermostat operates on a bimetallic coil principle.
  • It utilises two different metals bonded together, each with different thermal expansion rates.
  • When the temperature changes, the bimetallic coil expands or contracts.
  • The bending of the coil actuates a switch mechanism within the thermostat.
  • The switch either opens or closes an electrical circuit to control the heating or cooling system, depending on the desired temperature setting.

Features

  • The sensor element of Johnson Controls A19BAF-1C thermostat is unaffected by changes in barometric pressure or cross-ambient conditions.
  • This unit has a concealed set point dial with an adjustable differential.
  • It features a NEMA 1-rated galvanised steel enclosure to prevent the entry of air contaminants and protect the unit from accidental drops.
  • This unit can control the temperature within the range of 30 - 110 degrees Fahrenheit.

Compatible Accessories

  • Johnson Controls KNB20A-602R Knob: It is used to adjust & set temperature or control settings on HVAC and industrial equipment. This knob allows for precise and convenient temperature or control adjustments, enhancing the usability and functionality of the equipment.
