W500 Floor Heating Thermostat - wiring question

[martincooper]

I’ve bought an Aqara W500 thermostat to replace my Honeywell BDR91 in my underfloor heating system and am not sure which wires go where in the W500 because the BDR91 currently has two lives whereas the W500 only has 1. See picture which shows the current wiring into the BDR91. Any ideas? Many thanks.

Hi, which wire is just a jumper A or B?

[martincooper]

Thanks for the reply. B is the jumper.

Do you understand what needs to be connected?

As I see it, it should be like this.
