Question about tado° Smart Radiator Thermostat X - Single Pack

Hello, Can anyone tell me the exact dimensions? I know that they are 67 x 67 x 49mm, but which dimension in which direction from where exactly. Even Tado can't give me a sketch or dimensional drawing. But the size is relevant for me, as I only have very limited space available. And I don't want to order one on the off-chance that it won't physically fit. So if anyone has one to hand, I would be very grateful for more precise information. The decisive factor would be the dimension from the valve to the front, i.e. how far it protrudes. That would be the most important thing. Thank you very much for your help.
