Hi All,

I have a Potterton Prima 60F and about a week ago I was getting power on the switched live when a call for heat was requested. I played around with the CH zone valve and the boiler started to fire so I thought all was well. It wasn't! I'm not a plumber by trade but am not bad at DIY electrics.

The issue I have at the moment is that when I select CH on all the time from the programmer the valve opens but the pump does not start. If I turn off the CH and turn on the HW from the programmer the pump starts up. Should it not be the other way around?

I have a HW cylinder and 2 x 2 way Tower zone valves.

Cheers
Daz
 
No such thing as diy electrics.

Need the testers out and trace the fault. Tower valves are pants.
 
Sometimes M valves open but wear in linkage means micro switch does not engage.
 
I agree , a screwdriver that lights up just doesnt cut it , best to get a qaulified electrician in b4 you set your house on fire , thats how accidents happen Daz

Hi,

 Our heating stopped working today. We've got a Veissmann boiler that's under a year old, and an older Megaflow cylinder, and two diverter valves (all about 10 years old). We also use a Hive thermostat.

 When I boost the hot water with Hive, the receiver near the boiler shows it's...
