Why am I feeling too cold/hot in my living room with my Daikin Thermostat?
- G
  Glen StewartAug 31, 2025
  There are several reasons why you might be feeling too cold or too hot. It could be that the desired room temperature is set too low or too high; in this case, increase or decrease the desired room temperature accordingly. If the desired temperature cannot be reached, try increasing the leaving water temperature, keeping in mind the heat emitter type. Also, the weather-dependent curve might be set incorrectly, so consider adjusting it.

What to do if Daikin Heat Pump water flow is too low?

  Katelyn MathewsAug 30, 2025
  If the water flow is too low, check and ensure that all shut-off valves of the water circuit are completely open, the water filter is clean (clean if necessary), there is no air in the system (purge air if necessary), the water pressure is >1 bar, the expansion vessel is NOT broken, the valve (if equipped) of the water circuit towards the expansion vessel is open and the resistance in the water circuit is NOT too high for the pump.

Why is the water at the tap too cold with my Daikin Heat Pump?
- L
  Larry DouglasAug 27, 2025
  If the water at the tap is too cold when using your Daikin Heat Pump, it might be because you ran out of domestic hot water due to unusually high consumption. If you need hot water immediately, activate the DHW tank Powerful operation. Keep in mind that this will consume extra energy.

What to do if Daikin EHVZ-E9W Heat Pump fails?
- T
  tuckerethanAug 26, 2025
  A Daikin Heat Pump failure can stem from several issues. It could be due to damage to the heat pump itself, in which case you should consult the help text for malfunctions. Another cause might be air trapped within the system, requiring you to purge the air. Also, an incorrect hydraulic balance could be the reason; the installer needs to perform hydraulic balancing to ensure correct flow distribution. Finally, various malfunctions can trigger a failure; check the user interface for error codes and consult the help text for malfunctions.

Why is my Daikin EHVZ-E9W not sufficiently heating at low outdoor temperatures?
- V
  Victoria MedinaAug 23, 2025
  If your Daikin Heat Pump isn't sufficiently heating the space at low outdoor temperatures, it could be due to several reasons: * The backup heater operation might not be activated. Ensure the backup heater operation mode is enabled. * The backup heater overcurrent circuit breaker might be off. Turn it back on if it is off. * The thermal protector of the backup heater might be activated. If it has, check the water pressure, whether there is air in the system, and the air purge operation, then press the reset button in the switch box. * The backup heater equilibrium temperature may not be configured correctly. Try increasing the equilibrium temperature to activate the backup heater operation at a higher outdoor temperature.
