Dinosaur Electronics 12V Furnace Fan Time Delay Relay | 12VDCTDR (TDR)

Gives an old furnace a proper fan cycle. The Dinosaur Time Delay Relay holds the blower 4 seconds so the burner lights first, then runs it 2 minutes after the burner shuts down to clear the heat — protecting the heat exchanger on furnaces that never had a delay.
