Programable stat which locks out W2
I don't want my high efficiency gas furnace to run on second stage high fire until a predetermined outside temp has been reached. The White Rogers 95 series has the outdoor sensor which locks out W2 above a certain temp while in heat pump mode. But Im not sure if it locks out above a certain temp in 2nd stage conventional furnace mode.
Does anyone know if it would work with my carrier infinity furnace or recommend a stat which would?
