197     lower:the Minimum cooling state can be used for this trip point.
199 	  and the cooling device can be in cooling state 0.

218     .cdev: The cooling device pointer
219     .weight: The 'influence' of a particular cooling device on this
220              zone. This is relative to the rest of the cooling
221              devices. For example, if all cooling devices have a
224              weight of 0 means that this cooling device doesn't
225              contribute to the cooling of this zone unless all cooling
