Replacing my oil primary controlFriday, February 01, 2013
This product was a direct replacement for my old primary control. It was easy to install and wire.
everything, it is a quality product.
The instructions to install it using a regular, or high volt(27 volt) thermostat. You have to loop the "T" terminals for the burner to fire.

Spare Parts On-HandWednesday, January 04, 2012
As a retired aircraft mechanic, I like to have critical spare parts on hand. In the dead of winter it is nice to have a replacement relay on hand if the furnace should fail. We also have an oil-fired hot water heater and I am no longer a fan of cold showers when I'm not camping!!
The ability to procure one with no middle-man
It's all good for me!!!!
