Worcester Greenstar 30i and Meross MTS200 Smart Thermostat

[JohnHamer1977]

Hi all, as per title I have a Worcester Greenstar 30i boiler that doesn’t have a thermostat installed, just the MT10 timer.

I’ve bought a Meross MTS200 Smart Thermostat.
I am not 100% on the wiring so would this be correct: (Remove link from LR)

L from the thermostat to L on the boiler.
N from the thermostat to N on the boiler.
NO from the thermostat to LR on the boiler.
The sensor in 6+7 (then where does the end of the sensor go?)

And there is a little link cable supplied with the thermostat, I’ve seen people on other posts putting that between COM and L on the thermostat, is that required/correct?

What cable should be used?

Please see pics attached.

Thanks in advance!!

Link L to Com at thermostat and these three wires used

plus the earth. The sensor is not required in the boiler version, there are three versions of that thermostat.
