About This Product

Product Info


Electric furnace sequencer, 24-volt (AC). One control switches fan and up to three elements on and off in sequence. Isolated fan switch has positive interlock to assure fan is on when element is on, and fan is off when element is off. Replaces any of ten models in Honeywell line and many competitive devices. Combination rating on first element switch allows replacing devices having fan and first element controlled by the same switch without rewiring furnace. Auxiliary switch controls second R8330 in application with more than three elements. Cycles on within two minutes, off within four minutes. Ten-second minimum delay between stages (makes sequence and break sequence.) Timings meet EEI-NEMA and ARI 280 Standard.
