[QUOTE="Phoenix, post: 495497, member: 8133"] General thoughts are, The pump associated with each boiler should be run from the pump overrun terminals on that particular boiler. The main circulation pump should be run whenever there is a call for heat as otherwise when the boiler is in cool-down it'll only be able to dump heat into the pipework in the plant room, so either main pump running whenever any of the boiler pump overruns are running, or have its on its own overrun (probably easier) set to run just a bit longer than the normal overrun on the boilers. Pressuration unit needs a supply, and you probably want to do something with the fault signal, very least light an indicator lamp, prossibility inhibit the system. I can't imagine the system would be very efficent without termperature sensing and sequencing. It sounds like the system is being chucked in without any proper design of the mechnical side, and while, yes, you'll be able to wire it to make it work, its not clear if it'll work well [/QUOTE]
