The Copeland Comfort Control (White-Rodgers) 24A34-3 is a 2-switch electric heat sequencer for electric furnaces and heat pump systems. It manages 24V control input to activate heating elements and blower motors in staggered sequence, preventing inrush current overload. Features 1–20 second On timings and 40–110 second Off timings, with M1–M2 contacts ensuring blower initiates first and terminates last for safe heat dissipation. Rated 25.0A resistive at 120/240/480V and 14.0 FLA / 72.0 LRA at 120VAC. Direct replacement for Honeywell, Mars, TOD, Gemline, and Klixon sequencers.
