    It can be caused by a poor connection or a faulty relay coil.

    It would help to have a bit more informations, such as type of control and thermostats.

    Have you attempted to isolate the boiler from the thermostats to identify where the problem lies? If you are using a zone control relay such as a Taco SR503 you can remove the thermostat connections and install a jumper wire to test the relay contacts.

    Good luck.

    t-stat

    Have you checked the anticipator on the T-stat? Most times that's your culprit.
