Could be different using the mobile app with cloud solution !

Using the CCU yes, you need thermostat to create direct link.

Yes. Exactly what I'd like to know.

I'm sorry I can't answer that question, I only use CCU.

Well, it IS ok, the WHS2 is completly capable of potential free switch, I'm currently using it since tonight :)
Dear Petoulachi,
could you show me how you connected the dry contact (potential free) of the boiler to the Whs2?
It also be possible to have a photo of the connections?
There is no indication in its manual.

Thank you very much
ps: I'm not a owner but I plan to do it

Hi,

I attached a picture of my own wiring. Please don't pay attention to the NON-STANDARD wire colors, they were already as such when I bought this house :oops:

This device has 2 switches. It is wall-mounted right where the old home-wide single thermostat was placed before.

To reply to an older question about "trigger the boiler when valves open more than X%", I actually rely on a couple of things (of my own understanding, I may be wrong) :
- either a CCU association/program to trigger the boiler when needed (x%)
- or thermostat device-to-device association ==> for this one you may set the hysteresis to something high enough to trigger your boiler only when a high temperature margin ensures for the valves to be open enough. The default is 0.4°C.

Cheers.
