The tado° Heat Pump Optimizer X is compatible with Daikin heat pumps. Here is some helpful information before you get started.
Can I use the Daikin Onecta App and tado° together?
Yes, typically you can use these apps together.
Most new models of the Daikin heat pump use a WLAN adapter SDcard, which can stay inside the heat pump even when the tado° Heat Pump Optimizer X is installed and will maintain contact with the Onecta App.
Exception: If your heat pump uses a Daikin LAN Adapter, you will need to disconnect it in order to connect the tado° Heat Pump Optimizer X. This will disable contact with the Daikin Onecta App. When you install the tado° Heat Pump Optimizer X, you will receive instructions for disconnecting the Daikin LAN Adapter.
Tips about domestic hot water (DHW) behaviour in Daikin heat pumps
Some Daikin heat pumps limit the maximum output temperature of domestic hot water once the outdoor temperature reaches a certain threshold. For instance:
When outside temperature reaches above 25°C, the maximum output temperature is limited to 45°C.
When outside temperature reaches above 35°C, the compressor will shut off.
Please note: this logic is built into the heat pump and can’t be adjusted by tado°.
If these temperature limits are triggered when the outside temperature is under 25°C, the outdoor temperature sensor may be exposed to the sun or defective.
Compressor vs. electric booster: Some Daikin heat pumps may use the electric booster instead of the compressor when domestic hot water is requested. You can change this setting, but the benefit of doing so depends on your setup. Daikin documentation and tado° customer support can help you determine which setting to choose and how to disconnect the electric booster. Please note that disconnecting it at the fuse will result in inaccurate consumption data, because the heat pump will assume that it is still running and will calculate as such.
