Potterton and RWB2E Issue

[Houman Irani]

Hi,

I just moved to a new flat. The heating and hot water consists of the following parts:
1-A potterton profile boiler
2-siemens RWB2E programmer
3-A honeywell knob on the wall
4-a big tank and complicated system in storage!!!

The issue is when I turn on the heating with programmer, nothing happens but when I turn on the hot water the heatins works as well. But I want to control them individually.

I am new to this kind of boilers and so I dont have any clue what is the issue or is there any issue at all?

Thanks All
