The FAN tab allows user to control two fans (hot side fan and cold side fan) independently by turning
on fans permanently, only in heating mode and/or cooling mode, during specific temperature set
points, during specific hysteresis range, under specified voltage limits or turning off during specific
dead bands.
Fan Mode List
The FAN mode works as follows.
Off
FAN is always off.
Always on
FAN is always on.
Cool
FAN is active when the regulator is in cooling mode.
Heat
FAN is active when the regulator is in heating mode.
Cool and heat FAN is active when the regulator is in cooling or heating mode.
Algo
FAN is active as result of an algorithm function.
FAN Algorithm
Algo mode runs the FAN by tracking the input temperature. The output is given by the temperature
and settings. Any sensor can be used for monitoring temperature.
