Seimens RWB2e programmer

[johnscts]

I fitted this unit a while back for my son. He informed me NOW that he is unable to switch off the HW independently when the CH Is ON. Unfortunately he lives away from me - I need to know if the DIP switch is wrong (Should it be on 10 program or 16 program with operation of the slider unit[/b]

Let's have some details of the system.
Fully pumped or gravity dhw?

 

[johnscts]

Thanks for the support the system is gravity fed

Gravity fed or gravity DHW?
If gravity dhw, then no heating without hot water. A gravity fed, or open vented can still be fully pumped. Are there any motorised valves?

 

[johnscts]

The system has 2 valves (2 port) and both are energising (opening to pass hot water flow. As before I suspect the programmer (I read a screwfix customer who said she went through 2 which packed in) would the 10 program or 16 program dip switch have any bearing on this problem - I am hoping in the next day or two to move the slider over from present position
Again Tks for your response

It needs to be in the 16 dip position to give independent control, it comes in the 10dip setting, u have to change when u install

Many thanks - I will try that but that won't be until Monday kind regards. John[/b]
