Exceed the maximum value to ‘unlimited’ instead of 25 degrees celsius
Currently the maximum setting (high) for each device is 25 degrees celsius. In the same way you can put the lowest setting to ‘Off’ there is a need to have a setting for the highest value of ‘Unlimited’ or ‘Full’ or ‘Open’ Instead of the limit of 25 degrees celsius.
This is for instance needed during summer when the temperature is already high in the bath room but still need the radiator (temporarily) working to dry your wet towels.
Also in some cases you want to test the central heating / boiler in the summer but cannot due to the temperature being 25 degrees celsius or higher.
