    WANTED: Grundfoss Pump Plan UPP15-50 Wiring Centre

    Hi Agile, Many thanks for your uplifting response :) If I can't find a replacement, I'll try CET. The local sparky took one look at the PCB and reckoned it was beyond repair - components not identifiable, extensive track damage on PCB, etc. So I won't be holding my breath. If you get bored...

    WANTED: Grundfoss Pump Plan UPP15-50 Wiring Centre

    Hi Razor 900: I'd rather stick with 2 pumps. My experience with zone valves in hard water areas has been disappointing - they have repeatedly failed within 2-3 years whereas the pumps have never needed to be replaced. Given the system in this property, acquired last year, probably was installed...

    WANTED: Grundfoss Pump Plan UPP15-50 Wiring Centre

    Hi all, Some years ago Grundfos introduced Pump Plan, a two pump heating system with a wiring centre containing a relay, as an alternative to using the zone valves required by S-plan and Y-plan. This product has been discontinued for some time. I can replace the dual-pump with two 15-50s or...

    Extending supply from garage to another outbuilding

    Hi winston1, many thanks for your response. My bad - I've checked the consumer unit and that 20A is labelled "garage sockets and outbuilding lights". The 32A is labelled "garage and laundry ring". There is also an additional 6A labelled "laundry lights". The electrics were checked and...

    Extending supply from garage to another outbuilding

    Would appreciate advice please. Our detached garage has power and lighting circuits supplied from the consumer unit in the house. The sockets are connected to a B32 on a 63A 30mA RCCB. The lights are connected to a B20 on another 63A 30mA RCCB. The garage lighting circuit has been extended...

    Fully pumped system with no zone valves - how to add room thermostat?

    Seemed clear enough to me! Perhaps you should offer your services to Honeywell, as they seem to limit their support to what you can read for yourself in the wiring instructions (if, that is, your system is the same as one of their plans ....)? :) Have a fine weekend and take good care!

    Fully pumped system with no zone valves - how to add room thermostat?

    Hi Stem, Thank you so much for taking the trouble to explain the probable setup. I'll replace the Sangamo with the Sundial set for gravity and live with the lack of independent control for the time being. If we actually get a summer next year and sparkies become available once more, I'll...

    Fully pumped system with no zone valves - how to add room thermostat?

    Hi all, some help required please! We've moved and inherited an oil-fired heating system with two pumps (CH and DHW) but no zone valves. There is a cylinder stat but no room stat, so we would like to install a wireless room stat. But I've not come across a two pump system before (although I...

    How to replace Sangamo Choice PR2 with Sundial RF2 Pack 2?

    Mea Culpa - the issue is more complicated than I thought - Although the Sangamo programmer has its dip switches set to 'gravity', the system is actually fully pumped. But there are two pumps (one CH, one DHW) and no zone valves - I'm told this was not unusual for oil-fired boilers on new builds...

    How to replace Sangamo Choice PR2 with Sundial RF2 Pack 2?

    Thanks Chris, but those docs don't suggest that there are any DIP switches on the Sundial :(

    How to replace Sangamo Choice PR2 with Sundial RF2 Pack 2?

    Hi all, Would very much appreciate some help here. We've moved to a new property that has a Grant Euroflame 70/90 oil-fired boiler and a Sangamo Choice PR2 two-channel programmer with cylinder stat but no room stat. The Sangamo has a standard backplate with a black wire for HW=ON (t3) and a grey...
