Tips

For best results, mount the thermostat on an interior wall at a height of about 1.5 meters, away from direct sunlight, drafts, or heat sources. This ensures accurate temperature readings. Use the holiday mode to save energy while you're away, and the boost function for a quick warm-up when you return. Pair it with Homematic IP radiator thermostats for room-by-room control.
