Hi
Our central heating system is currently controlled with a Honeywell ST699, which appears to not allow us to control the time of the heating & Hot Water separately, or have a boost function.
We've thought about changing it for something like the Siemens RWB29, which seems to have some reasonable reviews and would allow us to do these things.
Just wondered, is this likely to be a nightmare job and only one for an expert?.... I consider myself to be a reasonably competent DIYe'r and have in the past done some basic wiring etc but am not that familar with how the wiring of central heating works
Thanks
Brittas
