siemens rev100 control will not show the current temp

[boazlev]

Hello there,
I recently replaced my old mechanical control for the central heating with a digital Siemens Rev100 control.
My electrician installed it but later lost the user and installation manual, and thus i am left with a unit that seem to turn on the central but cannot set it.
The control does not show any room temperature and i can also not calibrate it (in calibration mode no command can be entered on the touch screen, no temperature is showing either).
All in all I have the feeling that the sensor is not connected / operating.
Does anyone have experience with this?

a little lost, so thanks a lot for any helpful remarks!

thank you for this quick reply and the manuals.
still the problem is not solved as i can't get a temperature read as soon as the control comes on, after a battery change or after a hard reset.
could it be that my unit is defected?
I've posted a request online for support from Siemens, we'll see if that helps.
I also encountered 2 additional problems:
- batteries are "dead" within 24 hours. tried a few sets of new batteries.
- the remote logo on the screen appears at all times, although the unit is not connected to T1/T2 so no remote control should be available.
