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
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.
