having only 1 thermostat control both systems.

avoid using a switch as I had originally proposed,.

I don't know if there's a right way to do this, as there are many ways to probably design this control system. I can also see the problem with the defrost call from the heat pump to the furnace would be an issue. Your Diagram makes total sense, I can definitely see how you are switching between heat pump and gas furnace using a simple switch on the W terminal. I have seen this thread and think it is a similar problem they are using some relays to trick the thermostat. If I flip a switch, thermostat switches from heat pump to propane furnace. So basically, when odt drops below 32, thermostat switches from heat pump automatically to oil heat. I know there are many concepts out there like one / two stage systems, aux/ emergency heat thermostat wiring.īecause of this, I am somewhat confused as to how I could take advantage of some of these thermostat features to wire the system in a way that could at the very least approximate the use case I am looking for.

In other words have some kind of switch or override that I can toggle manually to select.īecause the oil system is forced hot water, the thermostat doesn't need to run the fan at all when the system cuts over from heat pump mode to the oil boiler forced hot water system. I would still like to be able to run the furnace / heat pump using gas, but only when the oil boiler system goes down. I only want to have the propane based furnace operate during an emergency situation, the only emergency would be my existing hydronic oil boiler forced hot water system going down. What I want is for the thermostat to switch to the existing oil boiler system instead of switching the forced hot air system to propane when Temps drop say below 32 degrees.

Typically you would install the new ducted hybrid heat pump system by wiring up the thermostat so that once the odt (outdoor temp) drops below some preset temp, the system will switch from heat pump mode to gas furnace. While I'm at it, why not save money by installing a hybrid dual fuel heat pump, that way I can save on oil during the winter shoulder months.Take advantage of the fact that I am adding a ducted system to the home to add a second or backup gas based heating system to the home in case my oil boiler ever quits or dies on me.Add a central ducted a/c to the home for summertime cooling.I currently have no central ducted a/c in the home. This system works perfectly for the record. I have an existing forced hot water baseboard hydronic heating system that operates with a heating oil boiler. Hi there first post here so thanks in advance for all your help.įirst a snapshot overview of what is existing.
