Help with installation / diagram

Former Community Member
Former Community Member
Hi,


I am after some help with a heated windows installation / diagram - grateful for any input.

Unfortunately, the company supplying the installion went bust and I have been left with a system that doesn't  work (incorrectly designed).

We had a local electrician do the first fix wiring based on the diagrams but he says what has been sent won't work in it's current state and he doesn't have the relevant expertise to adjust it.

We live in a rural area and electricians are not that common especially for something as complex as this.

Rather than post up the diagrams and go into too much detail initially, I just wanted to know if this is a place to ask for advice and if not could anyone point me in the right direction. e.g contact details for an electrical engineer.


Thanks.

    The SSR will be 'solid state relay' and looks like their enable signal (would be a coil in the old days) is driven by the 230V thermostat, but the actual window heaters are transformer isolated. The fact the windows are all weird and wonderful voltages is presumably a feature of their area and aspect ratio (long thin/short and fat), and appear to have been grouped into 4 voltage bands  57, 76 , 89, and 150. (no wet noses on the glass then ! )


    Total power (sammelstellung) of a touch under 10kw suggests that the overall cable needs to be man enough for about 40 to 45A, and the transformer needs to be set for 230V single phase input, not 400V 3 phases.


    The Germans commonly have 3 phases to the house, so 3 phases at 16a each (2.5mm 3 phase radial) is probably the maker's original expectation - such a thing is a common sight for a cooker supply or an instant water heater.


    I think a photo of the transformer may help, and late, assuming it can be set for 1 phase then perhaps carefully powering it on and looking at the output voltage on the secondary terminals with a meter before connecting any windows.
