I've been thinking of installing a normally open relay on the steam boiler auto fill probe, such that when the brew lever is engaged (micro switch powers pump), the relay will energise and short the water level sensor wires. This would ensure the steam boiler does not refill mid shot. This seems like it would be quite a simple mod, but I can't seem to find anyone who has done it before. I like that idea though I'd do it by cutting power to the pump, not messing with the fill probe. Don't really want an extra connection in that wire. Another idea is to install additional plumbing and a solenoid valve such that the steam boiler heat exchanger could be mechanically bypassed. This would allow higher steam boiler pressures without overheating the brew boiler. Or alternatively leave out the relay, and install a restrictor such that water splits roughly equally between the heat exchanger and non-heat exchanger paths to the brew boiler. If you're pulling enough consecutive shots that the brew boiler is overheating, maybe, otherwise, why? -- Ira -- You received this message because you are subscribed to the Google Groups "Brewtus" group.
