Thermostat buttons or touch keys are hard to press or unresponsive in certain areas

Safety: Disconnect power before removing the front cover.

• Step 1 – Clean surface: Wipe the front panel with a soft, slightly damp cloth (water only). Dry thoroughly.
• Step 2 – Check mounting: Ensure the thermostat is firmly clipped onto its base and not flexing when pressed.
• Step 3 – Test via app: If available, use the Immergas app to change settings instead of the faulty keys as a temporary workaround.
• Step 4 – Replace unit: If specific keys or touch zones remain unresponsive, the front panel or keypad is worn and the thermostat should be replaced.
