Hello @AqaraOfficial and forum members, I have a central heating system at home, we have a central boiler with a solenoid valve each, water radiators at home and a normally open circuit thermostat. The thermostat closes the circuit once the temperature is below the selected one. It works wired to close/open the circuit and battery powered.
Nowadays I use the Tado X thermostat, I’m guessing if @AqaraOfficial has any wall emblem thermostat that could work with my heating system.
I tried with the S3 and it didn’t work.
A bit off-topic; I was really hoping the Touchscreen Dial v1 would function as a thermostat to. It would have been perfect using a dial for temperature like old thermostats had.
Hi @correoto, what exactly didn’t work with the S3 thermostat in your setup? I’m curious, because I use several S3s in my house and they work well for me. I don’t have radiators though – my system is a water-based underfloor heating. Each floor has a manifold with valves, controlled by small actuators, and the S3 thermostats handle those actuators without any issues.
Out of curiosity I also ordered a W400 thermostat from China, since it can control not only heating but also air conditioning. The W400 is a much more complex device with lots of connection options. When you start it, you can even select the type of AC unit to control. I haven’t finished connecting and testing it yet, because the documentation is really basic and I don’t have all the knowledge myself. But here in Austria our summer break is ending soon, and once my electricians and HVAC specialists are back on site, I’ll dive deeper into the W400.
Always remember: “If your car is smarter than your home… you’re driving into the future while living in the past”
Hi @RudyK and @AqaraOfficial , thank you! The problem in most European community heating systems, is that thermostats work as a switch, they are not powered, that’s why they need batteries, Tado is a good solution because they have disposable or rechargeable batteries, others like Nest or Netatmo ones must be powered 12v.
Hello, if I understood you correctly, then you have the same problem as me. Each battery has its own electrovalve. I solved this issue in this way, you can take a look. Methods for controlling room temperature using Aqara devices At the moment, I would recommend you the W500 to which to add an additional relay (220 volts) that will have the dry contacts you need. Also, the W500 works great in conjunction with the W100. For information to users, the capabilities of the W500
Hi @gafich10 ! @aqaraofficial W500 is compatible with a NC (normally closed) electric circuit, but our thermostats are for NO (normally open) electric circuits.
Thanks!
@correoto
Once again, for clarification. When the room is warm (no heating) the contacts are open. When the temperature drops below the set temperature, the contacts close (heating occurs). I am writing this to avoid misunderstandings due to the language barrier between us.
Sorry for repeating myself.
