I have straight A/C with a boiler for hot water baseboard heat. I would like to switch to a hybrid-type system where the heat pump heats initially, but when it calls for the backup heat/heat coils to come on, I want it to power up the boiler instead.
As I understand it, with an Infinity Control, the only way the heat pump can power on the boiler as desribed is if it's paired with a Carrier boiler, but mine is not. Apparently, the only way it will work this way is if I use a Thermidistat instead of an Infinity Control.
1.) Is anyone aware of any other ways?
2.) Does that defeat the purpose of getting an Infinity System?
3.) What capabilities do I lose by using a Thermidistat instead of an Infinity Control?
