wondering if anybody could help - I have a two zone system. One zone is working blowing warm air the second zone is not blowing just cold air . The menu screen is blue and modulating so it is not a lockout issue. The red light flashes on my zone two I think relay? Not sure why one zone works the other not ?

Its not the boiler, it's that Hydro coil zone only. Air in the heat pipe to the coil, bad circulator, bad relay.
The fan comes on automatically with a heat demand with your setup.
The Red light on the Zone Panel shouldn't be blinking. It should be steady on if there's a heat call. What brand zone panel?
