How can I remove the ViCare Radiator Thermostat from the radiator?

Step 1: Remove the thermostat casing

• The release tab is located opposite the thermostat display. Press it very firmly with your thumb while simultaneously pulling the thermostat cover away from the valve and towards you.
• During this process, use your other hand to press on the Viessmann logo at the end of the thermostat to make it easier to remove the casing.

Step 2: Open the valve

• Press button A next to the display for at least 3 seconds until you feel a slight vibration. As soon as the display shows “- -”, the valve is open.
  This makes it easier to remove the thermostat.

Step 3: Remove the thermostat

• Press the release tab again while simultaneously turning the thermostat anticlockwise.
• The thermostat is now detached from the adapter and can be removed.
