Lochinvar hydro air - no heat when warm outside
I have a Lochinvar KBN boiler which uses hydro/an aquastat to provide forced air heating through Amana air handlers and an Argo controller. I was testing the system yesterday in prep for a home sale. It was ~70 degrees outside/inside and the heat didn’t come on even after setting the thermostat to 85 (boiler didn’t show any calls for heat). This morning it’s colder outside (~60 degrees) and heat came on after I repeated the test. Is this expected? I know Tekmar has a warm weather shutdown feature - does something similar exist for lochinvar/amana/argo? If not would the outdoor reset / heating curve settings explain this behavior?
