devi 550 screen not working : heating on : how to turn off?

noelectricexperience · 4 Mar 2020

My underfloor heating device timer/screen seems to be not working properly. The screen is completely off but the heating seems to be working sometimes. I believe it's only working at night but it could be at random.

Does anyone has advice on how to turn it off completely?
- If I disconnect the screen would the heating be turned off? Or should I also turn off the mains during a few minutes? Or perhaps something else?

Does it have a thermostat to control it? Is it linked into central heating?
