Product Description

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.
