Lennox 67K66 Heat Relay 3-PDT 24V

The Lennox 67K66 is a heat relay that is used in many HVAC equipment, such as furnaces and air handlers. It works like a switch; it manages the directing of electricity to the heating elements depending on the system’s temperatures. That way, it is possible to heat the system properly and under control in order to avoid overheating the system and causing some harm to it. It uses a normal 24V AC supply voltage with a frequency of either 50 Hz or 60 Hz. The Lennox heat relay can be used in a wide range of HVAC applications due to the maximum current it can handle of 8A.
