What is the best way to have the geothermal heat pump use less electricity when Integrated with mo OWB?
When the thermostat calls for heat my geothermal heat pump activates the furnace blower and both the geothermal heat pump and my OWB heat exchanger supply hot air through the furnace plenum. My question is is there a way to have the geothermal unit run less when the OWB is supplying 180* to the heat exchanger.
Thanks

My guess would be a two stage thermostat if you don't have one already

Clyde, I am by no means a pro with heat pumps, we rarely use them here in the northeast so check with your Hvac guys on this one but the job we did in Florida last spring was heat pumps and all we did was interrupt the TT wires on the heat pump with a strap on Aqua-Stat that breaks contact on temp rise, this gets strapped on to the incoming wood boiler line, the TT wire is also run through a relay ( we used an Argo non fused ) on a call for heat, the TT pulls in the relay sending 110 to the blower only and the Aqua-Stat breaks the connection to the heat pump all from your existing TT
