I had my oil furnace replaced with and electric furnace connected to an existing
Heat pump. I have found that the installers have used the existing circuit control board to control the furnace. Is it standard procedure to install new board when installing a new electric furnace to replace oil. Furnace is staged model 15 kw.

No SOP here to replace. Ok to use board. If it works it works!
