Room thermostat upgrade wiring

[Beasty1711]

Hi,

I’m just replacing my old PTR01 room thermostat with a Beok one and just wanted to double check the wiring before I pop something and then have to face the wrath of my wife…
The old wires and diagram:



And the new instructions:


My assumption based on this:

Blue (old 4) goes to N (new 3)
Red (old 1) goes to L (new 4)
Yellow (old 2) goes to 6

Does that look correct?


many thanks

It does as far as it goes. Terminals 5 and 6 are connected to a voltage free switch, so you would also need to add a link between L and terminal 5. Otherwise there is no power for the thermostat to switch.
