Control for window louver
To pass inspection for my (large) residential boiler, I need to set up the window louver such that the boiler gas burner will not fire unless the louver is open.
My current configuration uses a Belimo control to open the louver when the t-stat calls for heat, but there is no additional control to prevent the boiler firing if the louver does not open successfully.
So two questions: First, any suggestions on the the louver control to use for sensing when the louver is open? And second, any suggestions on how to wire the t-stat, burner, and louver control to meet the condition of not firing the burner if the louver does not open successfully?
