HeatLink max input power.

[Empira]

Hi,

I'm trying to install my HeatLink on a Vaillant VUW 280/3-5.

Where do I connect my HeatLink heat request?

If I put it on the 24V output on the board, the boiler turns off the moment I request heat.

The old thermostat worked with a 230V connection, and I wonder if I can connect 230V output from the boiler to port 2-3 on the HeatLink?

Hi @Empira , thanks for reaching out to us here. I would be happy to try and assist. 

Please check out this installation guide for the Google Nest 3rd Generation Learning thermostat. It explains what terminals require what wires and has examples for different types of systems.

Hi, I wanted to check in. Is there anything else I can try and assist with?

Hi Alex,

I just wired it with 230V and it seems to work. It would be nice to have this information in the manual.
