Feature Request: Make "Flow Target" Editable via User Interface

[paqpal]

Hi,

It would be great to have the ability to modify the Flow Target directly through the user interface. Currently, the system only allows viewing the parameters (8-0b, 8-0c, 8-0d) but not editing them.

Benefits:

• Improved Automations: Enables creating automations that better maintain the ΔT by adjusting the water flow, thus optimizing system performance.
• Greater Control: Helps maintain a more stable ΔT, increasing system efficiency and reliability.
• User-Friendly:

Additional Consideration:
It would also be preferable to allow customization of the climate curve in the future. However, this goes beyond the scope of the current request.

Thanks for your attention and the great work!

This is on the to-be-added list but I do not think it is a good idea to change this setting dynamically, because any field setting change requires a Daikin system restart. If you want to change the flow dynamically, you can have a look at intergas_circulation_cap.

Hi Thank you for your assistance. I was initially considering modifying the pump speed only twice a day, but the solution you suggested appears to be a better approach. - I would also like to kindly suggest implementing the unit_of_measurement and device_class for entity HC_15_param Param15_Temperature_0A. Currently, Home Assistant (HA) displays this parameter incorrectly in the history charts. According to Espaltherma, this parameter represents the refrigerant discharge temperature. - Additionally, I’m looking into the issue of the overshoot being stuck at 1°C. A technician from Daikin mentioned that this setting could be increased by configuring the system to heating-only mode. However, I need to verify this approach. - My next step is to understand the Daikin defrost algorithm and attempt to tweak it, as the factory implementation seems too dumb. I came across a user who developed an automation that tracks the running time and temperature to predict unnecessary defrost cycles. This automation restarts the heat pump to reset the running time, with a 3-minute restart period being more effective than initiating a defrost cycle. I'm not sure if this is within the scope of your project, but I thought it might be of interest. Thank you again for your support, your device is helping a lot and decreased power consumption by 5kW/h a day. Best regards, Paq

Thanks - I'll add your Param15 info to the param15 work on the todo-list.

Hybrid systems unfortunately have a fixed 1C overshoot which cannot be increased (actually it is an overshoot of max 1.9C due to rounding).

Defrosting has my attention, as the hybrid systems have problems with it, though I am more concerned about the unit not defrosting when it is needed giving COPs down to 1.2. Requesting a defrost manually is already implemented as a HA button. Extending a defrost can only be done by timely off/on switching; not sure whether the cost of that is really less than accepting it. Newer full-electric systems have much better defrosting timing.

Well, here in northern Italy lot of people (including me) saw machines defrosting when there's no need. Temp is around 2°C / -2°C. Only one time I saw back radiator frosted. Otherwise I could do my old trick to wrap outside sensor with a tiny foam, shifting outside temp by 2°C Sent from Outlook for Android<https://aka.ms/AAb9ysg>
