Carrier HH12ZZ205 Limit Switch L205°F-165°F

The Carrier HH12ZZ205 Limit Switch is an essential element of HVAC systems, which is aimed at controlling temperature in a particular range. This limit switch is used as safety switch to protect the equipment and to maintain efficiency in the system. It works through detecting changes in temperature of the HVAC system. When temperature goes high than the open set point of 205°F, the switch opens and breaks the circuit thereby switching off the heating element or the compressor. On the other hand if temperature falls below the close set at 165°F the switch closes the circuit and the heating or cooling process continues.
