Can you post the corresponding mqtt activity when doing this? Use i.e mqtt-explorer.

I get the same error - when set to “hot water only” it jumps right back to auto mode . I have the same pump as @nschille - mine is just the G2 model instead.
it says - write { “d051”: 8}
What value is in reg d51 if you manually set hot water only on the display?
I have just put the Heatpump in ‘hot water only mode’ and read “d51”: 4
Same here. Only mode 0, 1, 2 supported on my Danfoss DHP i guess.
Seems there is a variation then in which/how many modes are supported. Unclear if it is depending on model/year or something else.
What fw version (Heatpump not thermiq) do you have? What model of controlboard do you have?
Appreciate if you could post a picture…

If you don’t have more modes, I assume you then have disabled the external heater feature. Mine was off until I had the service man by to clean and adjust the pump here in start of the new year. I have following modes Off, Auto, Heatpump Only, Heater Only, Hot water only - so basically 5 modes 
@ThermIQ Any update? As I see on my G2 Thermia Diplomat the I have 5 modes. In register D51 each mode is reflected by: Off = 0, Auto = 1, Heatpump Only = 3, Heater Only = 4 and lastly Hot water only = 5
Are you sure about the value in d51? I think my implementation assumes value to be {0,1,2,4,8} i.e a single bit per mode. Then there’s a list of the name for each corresponding state
What’s your software version of the hp?
I have a Thermia Diplomat Duo Optimum 12.
Display ver: 1.40
I/O card ver: 1.1
When i manually write to register d051 I get the right modes on the pump with the following values:
{“d051”: 0} = “Off”
{“d051”: 1} = “Auto”
{“d051”: 2} = “Heatpump Only”
{“d051”: 3} = “Heater Only
{“d051”: 4} = “Hot Water Only”
With the HA integration I get the same issue with the “8 - “Hot Water Only” - it returns to mode “1 - Auto” after a few seconds. And if I choose “4 - Heater Only” the pump switches to “Hot Water Only” on the display.

Hi:) Anyone experience problems with the thermiq integration in the the latest 2023.6.0 HA release? My integration won’t load 
I’m new to ThermIQ and Home Assistant. The ThermIQ integration is working fine for me and I have set up automations to manage the hot water and room temperatures which work, but I’m struggling with the ThermIQ card. I have copied and pasted the picture files into www/community and having installed the custom cards in HACS, they are also in the www/community folder in their own sub-folders. When I try to install the ThermIQ card, I get the errors: “Custom element doesn’t exist: html-template-card” and it’s the same with numberbox-card and fold-entity-row. Any idea what I’m doing wrong?
These are HACS custom cards that are required for thermiq. Read the install instructions for a howto. A re-start might be required.

Yes, I’ve been doing my best to follow the instructions. Unfortunately a restart doesn’t make any difference.
