Dinosaur Electronics 12VDC TDR 12V DC Time Delay Relay
The Dinosaur Electronics TDR Time Delay Relay is for use in older furnaces
that use a standard 12 VDC ignitor board. It has a 4 second delya before
applying power to the fan motor, and a 2 minute cool down period at the end of
the heat cycle before removing power from the fan motor. It fits in the same
location as the original.
