Controlling thermostats

Hello guys

I have a project with 2 different thermostats. The owner accepts to change them.
Siemens RDF340
and
Neptronic TRO5404

How would i be able to integrate them with vera?or maybe change them?

Any ideas?

Changing them out with a z-wave compatible thermostat for 100 to 150 each would be the best way and give you the most control. I have a few TRANE’s that I use (ebay, new, 90.00) but there are many others.

I want a European thermostat :frowning:
trane is US frequency only

Didn’t see your location. There is plenty of European zwave thermostats.

I am in the middle east!
I want to install some Eurpean thermostats for the HVAC systems!
