MTN645129 replacement

[PiotrJakubczyk]

Hi

I'm searching Schneider Electric (preferable) product to replace old MTN645129 as floor heating actuator. Now it is connected with MTN6212-4044 that works as thermostat.

Also we are looking to replace MTN6212-4044 with something similar and still supported. 

Would be appreciated if solution would be as low engineering cost as it possible (similar functionalities, and naming convention, etc).

Hello @PiotrJakubczyk 
for MTN645129  we are currently using MTN6730-0002 valve driver controller.

but for MTN6212-4044, you can use system M MTN6212-0319 or the 4" TS but its in a higher cost
what do you think @Thomas_Rohde
