Auxiliary outputs and protection against CO2 poisoning

/ Section: AquaSky / Comments: 0

Another thing I finished on the unit is the auxiliary outputs. They serve to control supporting devices. Not only by time but according to the current or power of the light as well. This allows protection of the fish against CO2 when the light stops working.
