I know there is a way to wire up a heat pump to an older model nordyne LP gas furnace without the use of one of the factory relay kits.This furnace only has the single speed blower on it and 2 control wires (red/white) could you explain the way to connect this by just using a spdt relay? I have a dual fuel t-stat with a odt sensor at the condensor I just cant remember how to control the fan for the hp and furnace.The furnace is m#MGH-100AAWL-06 and is around a 1989 year model.
