I have just installed a mixer tap with shower fitting. The model is Greenwich /Hanover Bath Shower Mixer Taps 476409.
The water pressure from the hot tap is pathetic. I contacted the suppliers and they told me the tap requires 5 bar pressure(?) to operaqte properly.
I do not have a combi...
Help! I have purchased a new Thermostat/Controller (Siemens REV11) but it only has 2 connections and the old thermostat has 4 (see pictures at link below).
Which of the four wires should I connect to the new controller?
