furnace comes on with thermostats set at 50 (5 zones 3 pumps)
i don't know what to call this wirsbo/rinnai system so i call it a 'furnace'.
with all thermostats set at 50 degrees the system starts up and heats the house.
the 5 zones have never heated properly but now that i have to use the breaker box, we don't have domestic hot water until it is turned on again.
do you know of anyone in the Portland, Oregon area that i can call for help
