How do I recalibrate my Artos thermostat valve?

When adjusting the temperature for your F943-VO or F904A-VO valve, follow these steps:

1. Attach the handle without the temperature limiting ring (white plastic piece).
2. Turn on the water using the diverter or volume control handle, then adjust the bottom handle until you find your desired temperature.
3. Remove the handle without adjusting the temperature further.
4. Fit the temperature limiting ring over the securing nut.
5. Ensure the half-circle shape on the limiting ring is on the left.
6. Reattach the handle.

Following these steps, you'll set your preferred temperature and activate the anti-scald feature. To increase water temperature temporarily, press down the button; it will revert when you return to your ideal setting. Watch the accompanying video for a visual demonstration.
