Hi guys,
I got today two thermostats for my underfloor heating and trying to replace my ambiente thermostat which was originally installed. I am a bit confused with the wiring as I don’t know how to connect the N (load).
Here are the pics or the current setup of Ambiente thermostat.

From what I checked, I am missing cable for neutral (live). Chat gpt said that I may not be able to connect this thermostat and would need to use this ambiente.
Anyone had the same problem and knows how to solve it (connected it)?

Hi @gafich10,
I connected it already as I found in the manual the way to skip the N (load). Also chat GPT said to not to do bridges between. But your picture indicates to make the bridge between L (load) and N (load). Is this correct?

No, I drew a LOAD (electric heater)!!!
