ViCare Integration: Preset mode "home" does not exist and causes problems when applied using this integration (at least with a CU401B aka Vitocaldens 222-F)

[noseshimself]

The problem

If you read out the states of climate.cu401b_s_heizung

you will find the attributes

preset_mode: home vicare_programs: comfort, eco, fixed, normal, reduced, standby active_vicare_program: normal

If you use the Home Assistant controls, the Vicare app or the control panel of the heating to change the mode to any other setting and try to set it back to "Home" again using Home Assistant in

you will get the pop-up

and the heating seems to be drunk until turned off and on again (seems that Viessmann's plausibility checks in their controller software are not that good either).

1) Bug: It seems that "normal" and "fixed" were confused.

2) If you really intended to use "fixed": Fixed requires (according to the controller manuals for ModBUS communication) that an additional parameter has to be set; if it remains unset "it fails". Easy observation: It does something but not what you intended it too.
