I am a girly DIYer...I am going to replace my Honeywell T40 room thermostat in the hall with a Siemens REV11.
This is a wiring question which is products specific. I have to gather information but haven't found the exact 2 products to cross reference....
On the T40 the wires coming from the wall are wired as follows.
On the wall plate of the T40 there are 5 possible connectors.
In sequence it is wired up as follows, from left to right.
Earth to earth. (green and yellow wire)
Blue wire to connector 2
yellow wire to connector 3
Connector 4 is vacant (unwired)
red wire to connector 1
I have a new Siemens Rev11
It has two terminals for connection.
L and L1
I have ascertained that I don't need to earth it as it has a plastic back plate so that's that wire dealt with!
I suspect that the red (t40) wire goes to the new (siemens) L but not sure about the blue and yellow wires.
Am I right in suspecting the blue (T40) wire goes to the new (siemens) L1 and that I insulate the yellow??????
Help.....
