UTC Zone: Europe spans 7 primary time zones (5 of them can be seen on the map in
this article, while 2 other zones contain the European part of Kazakhstan and some
very eastern territories of European Russia). Most of European countries use daylight
saving time and switch to it at the same moment, which is 'harmonise' their summer time
adjustment
When European summer time is activated, it should change the time when the country /
UTC zone is doing it.
Holidays function is only available for room thermostat view of PC-ARFH1E. Holidays
let the user specify a date and hour for the Room Setting to be OFF with the configured
setting.
