Support for T8/T15 modes

[mstendah]

Hi, would it be possible to add support for the T8/T15 modes often used when keeping a basic temperature in a summer home etc. when you want to save on energy costs.

If I set e.g. T8 with the Comfort Cloud, the add-in now shows Heat and 8C, but when trying to adjust this in HA, I cannot go below 16C. So I can see that it is in T8 mode in HA, but I cannot activate T8 in HA.

Any thoughts on this @sockless-coding ?
