Did you get the install instructions for the INRAD roofing kit? There
are a couple different ways you can install it, one of which is to use
N1 or N2 soft switches to activate it. The other way, as it's installed
on mine (VI+), is to have the roofing filter installed full-time. I
have the 2.4K roofing filter.
