    Honeywell evohome pump over run problem

    i have just installed a honeywell evohome kit with a base pack, hot water kit and 8 hr92 rad valves i am having a problem with the pump over run as the evohome shuts the valves as soon as nothing is calling for ch or hw and the pump over run hit a blank.
    what i was thinking of doing is disconnect the ch valve put it in manual open and put a the bdr91 wireless boiler relay to where the pump orange was to boiler to call for ch. all rads with hr92 controllers except the bathroom rad that has got lock valves on so this one is the bypass for the over run will this work.
    Thanks

    Sorted now noticed I had gate valve on bypass Circuit so put a Honeywell du144 bypass valve on It ok now.
