Hello all,
Hope you are having a good day.
I'm looking to replace the analogue Siemens RAA21 thermostats currently installed in my flat with Moes Smart Thermostats. I am hoping someone here can guide me which would be the correct Moes variant I should purchase and also how they should be wired.
Some further detail...
These Siemens thermostats control the underfloor heating system. A number of these are fitted in various rooms/zones. When the setting increases beyond a certain point, it makes a click sound and I can see that the underfloor heating system is then activated. The underfloor heating system uses the Emmeti EWC-2 8 WAY WIRING CENTRE as its connection box.
Below are pictures of how the existing thermostats are wired:
and this is its official wiring guide:
I would like to replace all of them with Moes Smart Thermostats. These come in three variants with different wiring requirements, and I am unclear which variant would be the appropriate one for my scenario and also how it should be wired. Please see below the 3 variants and their wiring guides:
I assumed I would use the 'GA - Water Floor Heating' variant but that didn't work. My hunch is that I instead need the 'GC - Gas Boiler Heating' instead as that involves a dry contact, but was hoping to get some guidance from people far more experienced than myself in this area
Any assistance with this would be massively appreciated!
Thanks
Ratul
