I just got a new Evolution system installed, and it can certainly blow much harder than the old oil furnace I had before. In looking at the air handler parameters on the thermostat, it tells me the current CFM, Fan RPM, and Static Pressure. Does anyone know where this static pressure is measured? I'm assuming it can't know the return duct static, and it could know about filter static but I'm not sure if it does with this value. The value is about 0.33" with a CFM of 1400. Any idea as to whether I'm near the limits of the fan at this value?
