The Honeywell R8330D1039 24 Vac electric furnace sequencer switches a fan and up to three elements on and off in sequence. The R8330D1039 can be used on most furnaces using line voltage limits for 240 volt and 240/120 volt isloated fan and 240 volt combination rated wiring systems. It may also be used in pilot duty limit systems if properly wired.
Features
The Honeywell R8330D1039's 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. This control replaces any of the ten models in the Honeywell line and many competitive devices. The combination rating on the first element switch allows replacing devices having fan and first element controlled by the same switch without rewiring the furnace while an 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.
