Why is there no space heating by the gas boiler in my Daikin system?
- L
  Lawrence CooperSep 9, 2025
  If there is no space heating by the gas boiler, check the user interface for heat pump errors. Make sure the communication cable is properly installed. Check the settings in the heat pump manual. Switch on the gas boiler with if the service display displays " ", the gas boiler is switched off. Check the wiring and the connector X4 if there is no current (24 V). Replace sensor S1 or S2 if the burner does NOT fire on space heating because sensor S1 or S2 is faulty.

Why is Daikin Heat Pump space heating not reaching the desired temperature?
- R
  Russell GreeneAug 23, 2025
  If space heating isn't reaching the desired temperature, check the weather-dependent setpoint setting on the user interface and adjust if necessary. Increase the space heating temperature. Ensure there is proper circulation by having at least 2 or 3 radiators open. Also, verify that the boiler power has been correctly set for the installation. If there is no heat transfer, descale or flush the heat exchanger on the space heating side.

What to do if Daikin Heat Pump is not sufficiently heating at low outdoor temperatures?
- M
  Mark AndradeAug 25, 2025
  If the space is not sufficiently heated at low outdoor temperatures, check that the gas boiler is switched on and not in standby mode, the communication cable between the gas boiler and the indoor unit is properly mounted, and there is no error code on the gas boiler display. Also, increase the "equilibrium temperature" to activate gas boiler operation at a higher outdoor temperature. If applicable, ensure that the "space heating priority status" has been enabled and increase the "space heating priority temperature" to activate backup heater operation at a higher outdoor temperature. Purge air manually or automatically from the system.

Why Daikin Heat Pump hot water with tank installed does not reach the desired temperature?
- B
  Billy ReevesAug 27, 2025
  If hot water does not reach the desired temperature with a tank installed, check the display of the gas boiler and the indoor unit for error codes. Also, check the installation of the 3-way valve. In case of domestic hot water operation, the flow should be directed to the tank.

Why Daikin Heat Pump compressor does not start for space heating?
- M
  Mario KimAug 28, 2025
  If the compressor does not start for space heating, it may be because the unit must start up out of its operation range (the water temperature is too low). If the water temperature is too low, the unit uses the gas boiler to reach the minimum water temperature first (15°C). Check that the power supply to the gas boiler is correctly wired and the communication cable between the gas boiler and the indoor unit is properly mounted.

What causes Daikin Heat Pump tank disinfection function to not complete correctly?
- S
  Shelby PattersonSep 4, 2025
  The tank disinfection function may not complete correctly if it was interrupted by domestic hot water tapping. Program the start-up of the disinfection function when the coming 4 hours NO domestic hot water tapping is expected. If a large domestic hot water tapping happened recently before the programmed start-up of the disinfection function, it is recommended to program the start-up of the disinfection function at least 4 hours later than the last expected large hot water tapping. Do NOT press the button while the disinfection function is active.
