What to do if the water at the tap is too cold with my Daikin Heater?
- J
  Joseph GambleAug 3, 2025
  If the water at the tap is too cold when you are using your Daikin Heater, it could be due to high consumption causing you to run out of domestic hot water. If you need hot water immediately, you can activate the DHW tank Powerful operation, but be aware that this consumes extra energy. If this happens frequently, consider increasing the DHW tank temperature preset value or adjusting the DHW tank temperature schedule to heat the tank to a higher temperature during the day.

  Benjamin PerezAug 13, 2025
  If you're feeling too cold in your living room when using your Daikin Heater, it might be because the desired room temperature is set too low. Try increasing the desired room temperature. If this happens regularly, you can increase the room temperature preset value or adjust the room temperature schedule. Alternatively, the desired room temperature might not be reachable. In this case, increase the desired leaving water temperature according to your heat emitter type. The weather-dependent curve might also be set incorrectly, so try adjusting it.
