Strategy for climate control:

Cond 0: inside <= heating (10) 
|	-> heating needed
|	|
|	Cond 0 - Sub 0: outside >= preemtive heating (18)
|	|	-> fan
|	Cond 0 - Default:
|		-> heat
|
Cond 1: inside >= cooling (30) 
|	-> cooling needed
|	|
|	Cond 1 - Sub 0: outside <= preemtive cooling (28)
|	|	-> fan
|	Cond 1 - Default:
|		-> cool
|
Cond 2: inside > heating (10) 
|	inside < cooling (30) 
|	-> preemtive?		
|	|
|	Cond 2 - Sub 0: inside < preemtive heating (18) 
|	|	-> heating?
|	|	|
|	|	Cond 2 - Sub 0 - Sub 0: outside > preemtive heat (18)
|	|	|	  		outside > inside
|	|	|	-> fan
|	|	|
|	|	Cond 2 - Sub 0 - Sub 1: surplus >= minimum surplus heating (500)
|	|	|	  		surplus remaining > (minimum surplus heating (500) * change frequency (15)) / 60
|	|	|	-> heat 
|	|	|
|	|	Cond 2 - Sub 0 - Sub 2: outside > inside
|	|	|	-> fan
|	|	|
|	|	Cond 2 - Sub 0 - Default:
|	|		-> off
|	Cond 2 - Sub 1: inside > preemtive cooling (28) 
|	|	-> cooling?
|	|	|
|	|	Cond 2 - Sub 1 - Sub 0: outside < preemtive cool (28)
|	|	|	  		outside < inside

|	|	|

|	|	|
|	|	Cond 2 - Sub 1 - Sub 2: outside < inside
|	|	|	-> fan
|	|	|

|	|		-> off
|	|
|	Cond 2 - Sub 2: inside >= preemtive heating (18)
|	|	   	inside <= preemtive cooling (28)
|	|	-> optimal range reached, but check if preemtive useful because of forecase
|	|	|
|	|	Cond 2 - Sub 2 - Sub 0: forecast max >= preemtive cooling (28)
|	|	|	-> cooling?
|	|	|	|

|	|	|	|			 	surplus remaining > (minimum surplus cooling (500) * change frequency (15)) / 60
|	|	|	|	-> cool
|	|	|	|
|	|	|	Cond 2 - Sub 2 - Sub 0 - Default:
|	|	|		-> off
|	|	|
|	|	Cond 2 - Sub 2 - Sub 1: forecase max <= preemtive heating (18)
|	|	|	-> heating?
|	|	|	|
|	|	|	Cond 2 - Sub 2 - Sub 1 - Sub 0: surplus >= minimum surplus heating (500)
|	|	|	|			 	surplus remaining > (minimum surplus heating (500) * change frequency (15)) / 60
|	|	|	|	-> heat
|	|	|	|
