    Hi

    I have moved to a house that has a Firebird S 90-120. Picture attached

    Does anybody know what "C pump" does ?

    It's the central heating pump. Leave it on. The pump should only come on and off with the timer

    Strange to have pump on a switch like that. You would would imagine it would come on with the burner, even if controlled by a stat also.

    The grant euroflame utility boiler early to mid nineties has a similar set up with a pump on/off switch

    Any idea of the reason for doing it like that? Can't think of a situation where you would run the boiler, but want pump turned off.

    True. Now that I think of it, Ive come across a lot of those models that were piped via gravity circuit. I wonder did they do that, turn off the pump switch and it'd heat the hot water only. I always thought it was stupid as the water never heated with the pump on

    Boiler switched on = pump on
    Boiler switched off = pump off

    In regards to the timer.

    The only way it seems to work is if it's as in the attached picture.

    I would have thought it should have worked with control at 0

    Sometimes I have seen that switch (like on the SuperQ) used for a 'summer valve" motor valve.
