^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) if greater than 0, the following properties must be defined;
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) - tripN-temp : temperature of trip point N, should be in ascending order;
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) - tripN-type : type of trip point N, should be one of "active" "passive" "hot"

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) - tripN-cdev-num : number of the cooling devices which can be bound to trip
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) point N, this is required if trip point N is defined, set it 0 if none,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) otherwise the following cooling device names must be defined;
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) - tripN-cdev-nameM : name of the No. M cooling device of trip point N;
