Converting Vaillant thermostat to Tado smart thermostat
Hello,
My house has a Vaillant VRT350 thermostat fixed on wall. I want to change it to a smart thermostat and found Tado to be interesting so far.
Which model should I buy?
Here are my requirements on the device:
- I want this new device to facilitate me control the desired temperature by my phone.
- This should "NOT" control my hot water supply for shower. The existing system is already just good.
Here are my requirements on the installation:
- I am not good with electronics at all. I can only do basic electrical things like connecting lamps & switches. Not at all good with understanding complex circuit diagrams. So, the installation should be simple to replace existing thermostat with Tado. (No touching of the boiler at all)
- I don't want a system that expects me to change battery at some intervals - Thus, I prefer a wired system.
- [Question] If there is a wifi failure in peak winter, will the system at least ensure that the radiator pipes don't go below 5°C to avoid freezing.
In internet there was some info. about Opentherm vs relay that I couldn't understand well. Must I really understand it? Any specific concern of not paying attention to that?

Doesn’t fit your criteria. The Tado equipment uses batteries.
Vaillant might have something that works with your boiler.

Do we not have some wired Tado products?0

Assuming its a relatively new system it looks like a VRT350 is wired to the eBus terminal on the boiler as standard. Only certain Tado models can work via ebus, probably worth asking Tado with what you want to do.
You wouldn't be using the full capabilities of Tado if it was just to be able to change via the phone. Maybe look at the SensoHome controls from Vaillant as well if thats all you want to do as they will continue to use eBUs.
