I have an oil-fired circulating water heating system which has also the capability of producing domestic hot water. As I have switched to a GE electric water heating tank for satisfying our need in domestic hot water, I had to cancel the domestic hot water function on the White-Rodgers 8B43A-601 switching relay control (commonly referred to as an aquastat) so that the burner does never run to heat the internal water heating coil. For that purpose, I have removed the wire from terminal R and have connected it to terminal W, so that currect never reaches terminal B even though RB contacts remain permanently closed. Is that the way to go and will this procedure prserve safely the other functions of the aquastat?
