Change the boiler heating schedule of your Daikin heat pump

In order to make better use of external high temperatures during the day to heat the boiler, one needs to adapt the schedule for hot tap water heating. By default this is set to be heated when the tank temperature drops below a certain threshold. This setting can be overruled, so that the boiler will heat itself only once a day.

Steps to change the boiler heating schedule:

1. Go to User Settings (Gebruikersinstellingen) and press OK.
   
   
   
   
2. Go to Preset Values (Voorgeprogrammeerde Waarden) and press OK.
   
   
   
   
3. Go to Tank Temperature (Tanktemperatuur) and press OK.
   
   
   
   
4. I changed the temperature for Comfort and Eco to both 45 degrees Celsius. This will be the temperature until which the boiler will heat itself during the daily heating cycle.
   
   
   
   
5. Go back to the User Setting menu and go to the Defined Programs (Ingesteld Programma) and press OK.
   
   
   
   
6. Go to Hot Water Temperature (Warmtapwatertemp.) and press OK.
   
   
   
   
7. You have the choice now to edit your Own Program 1-3 (Eigen Prog 1). Select one and remember it for later.
   
   
   
   
8. I choose to set the Comfort program only to be triggered during the day at 16:00 from the months March until October. From November to February, I will schedule the program to run at 14:00. Remember to copy the program from Monday into each other day of the week and to fully save the new program.
   
   
   
   
9. Head back to the main menu and navigate to Select Program (Programma selecteren) and press OK.
   
   
   
   
10. Select Tank Temperature (Tanktemperatuur) and press OK.
    
    
    
    
11. Now select the Own Program 1, 2 or 3 (Eigen Prog 1) that you programmed just before and confirm the usage of it.
    
    
    
    
12. You can check the boiler temperature under the menu Information and then Sensor Information.

Below you can see how I make use of the higher outdoor temperature during the afternoon to heat my boiler. The red line is the daily heating cycle starting at 16:00. The yellow line is the outdoor temperature.
