I have an eko 40 with 500gal. tank. I have that loop controlled by eko control and primary pump. I have a secondary loop from the tank to the forced air gas furnace in the house. This is powered by a circulating pump and will be controlled by a thermastat in the house. I am presently trying to set up the thermostat so it runs the gas furnace blower (first mistake- learned how to turn the air conditioner while heating by wiring the gas furnace thermostat to the wood boiler thermostat). The gas furnace blower has a honeywell mini zone controller. I know I cant wire 2 honeywell thermostat to accomplish, but can I wire the would boiler thermostat into the mini zone controller (ie setting the gas furnace thermostat lower as back up for wood boiler) or do I have to wire the wood boiler thermostat directly to the blower with relay switch.......I am hoping all I have to do is parallel wire thermostats to the mini zone controller and set the thermastat accordingly (gas back up, wood primary).
