Honeywell R8330D1039 Electric Heat Sequencer Relay

Honeywell R8330D1039 Electric Furnace Sequencer. One control switches a fan and up to three elements on and off in sequence. Isolated fan switch has positive interlock to assure fan is on when the element is on, and fan is off when the element is off. Replaces any of the ten models in our line and many competitive devices. Combination rating on the first element switch allows replacing devices having fan and first element controlled by the same switch without rewiring the furnace. Auxiliary switch controls a 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 Standards. Replaces part R8330E1002 as well as several others.
