JJohntheo5 replied to the thread ABVs and Pump performance curves.Generally speaking, pump overrun is only required when all roomstats (or cylinderstat) are satisfied or the boiler is timed/programmed...

JJohntheo5 replied to the thread Bypass valve.I thought the "gas supply" was a bit on the hot side allright at 27.6C.:giggle: I think you're next move will be to try and convince WB...

JAh, I see what you mean… no, the 24.7 sensor display is in the middle but it’s metal sensor is inside some lagging wrapped around the...

JJohntheo5 replied to the thread Bypass valve.Slight hiccup?? The pipe where the 24.7C sensor is attached to is the GAS inlet I'm pretty sure and the Boiler Return is most certainly...

JJohntheo5 replied to the thread Bypass valve.If you can't access those values then OK. Were you able you located the position of the flow temperature sensor?

JJohntheo5 replied to the thread Setting a Pressure Reducer Valve on a maxiflo-fed power shower.You need a to have a flow through the PRV however small so open valves on either side of the PRV and adjust the setting screw clockwise...

JJohntheo5 replied to the thread Bypass valve.Can you follow the menu instructions in post 63 to see can you get those other readings.

JI'll list out what it said below. Though first worth mentioning I set the A2 to 0 and it still did the jumping from 20 to 80% thing once...

JJohntheo5 replied to the thread Bypass valve.Ensure you don't remove any casing that might compromise the boiler casing gas sealing. If you follow the boiler flow pipe back you...

JJohntheo5 replied to the thread Bypass valve.Let WB worry about the (if) 3 way valve. Write down or take a snapshot of these (especially temperature values).

JJohntheo5 replied to the thread Bypass valve.The boiler casing would need removing I would think to check for a 3 way valve. I have a feeling that some mix (or cock) up may occured...

JJohntheo5 replied to the thread Bypass valve.2-A2 if defaulting to 1 shows that there is a 3way valve installed, if so, then I'm not sure but it could mean that the boiler can be...

JJohntheo5 replied to the thread Bypass valve."but on factory reset 2-A1 is default 0, fine, 2-A2 is default as 1 on my boiler... so inconsistent with the manual" Low Loss Header...

JJohntheo5 replied to the thread ABVs and Pump performance curves.All those numbers are based on a ~ 30C dT, possibly because this is the limit to avoid excessive stresses on the HEX??.
