FAN PARAMETERS
F0
Management of fans: 0 = always activated fans except on specific
phases (see parameters F2, F3, and Fd)
1= fans controlled by a thermostat according to the difference
between ambient temp. and evap. temp.,
2= fans controlled by a thermostat according to the evaporator
temperature

F1
Fans activation temperature: if F0=1 it is the minimum difference
between ambient temp. and evap. temp. (t. evap. < t.amb.)
if F0=2, the fan is ON if Evap.temp<Se F1 - A0
the fan is OFF if Evap.temp. > Se F1
