Another Post by the owner of a Potterton Suprima 50 Boiler! Fortunately I don't appear to be having all the problems that have befallen so many of you.
We recently moved into our house which has an open vented CH & HW System comprising the following: Suprima 50 Boiler, Grundfos Pump and ACL Mid Position Valve.
With any combination of HW &/or CH everything is fine. Water in system reaches temp, continues to be pumped, cools, Boiler re-fires to re-heat the water. At this point the Pump stops and then a second or two later re-starts.
Is this a Suprima problem or a wiring problem?
Cheers

The pcb has to control things its own way to know they are working properly.
