One zone calling but floor cold

in THE MAIN WALL
Hi I’m new here-just moved into house with radiant heat (tekmar computer, watts manifolds and actuators etc.). Question 1: have one bathroom that is calling for heat but floor is cold. The watts actuator indicator shows open or on ( not red) the hose going into the manifold is warm, but the floor is cold. Could actuator be stuck?

Question 2: I bought some spare watts actuators-the ones installed are 2.5 watts. The supply house keeps shipping me the same actuator but they are 1.6 watts. Will they work?

Thanks!!

    Could simply be air bound.

    Issues w two adjoining rooms. One calling but no heat. Other not calling but warm.

    The cold room in and out lines are warm. I checked and changed the actuator today too.

    We would need to see a picture of your setup showing the manifold and boiler piping. Take it from as far back as you can so we can see as much in one picture as possible.
