Hi
I've just purchased a new thermostat to replace my wireless one (old one being Norstmann HRFS1), the new one being non wireless.
I've gone for a centaurstat 7 but am getting a little confused about the apparent 2 wire install.
From my vokera compact 24 i have four wires which go in to the current wireless receiver, two sets of live/neutral as in blue and brown x2
The new centaurstat 7 has 4 connection possibilities 1 through 4. does anyone know which goes where.
The manual says that this is obviously battery operated but surely the boiler still requires a mains power supply. Im assuming that one set of live/neutral (the current L & N) of the old receiver just get wired to the plug for the mains and that the other blue/brown (currently wired in to the com (brown) and NO (blue)) goes in to the 1 through 4 bit but im not sure which is which
Thanks
