I searched and couldn't find anything so I am asking if anyone has had any experience setting up thermostats / controls for an OWB with heat pump backup. I have a water to air hx in my plennum all ready to go when I get the OWB in a couple weeks. I have already spoken with my HVAC installer who tells me the air handler blower is controlled by a PCB. He said he's not sure how to break into the blower circuit without disrupting the heat pump's ability to control the blower when / if needed for backup. He said he would get a wiring diagram and try to figure something out. The heat pump is an Amana 13 SEER model with Goodman branded air handler. The air handler also has electric resistance coils to back up the heat pump when it can't keep up. Any help would be appreciated.
