The Lennox 72F83 Sequencer Relay Normally Open is an electronic component that is installed in HVAC systems to control the starting and stopping of different components in the system, to achieve effective performance. It works like an automatic conductor that switches on/off the equipment at the set time sequence. This specific sequencer relay is powered by a standard 24V DC power source and can be used in 50/60 Hz electrical systems. Such delays help to specify the exact time of functioning varied components of an HVAC system.
