Once the free cooling function is enabled, the unit controller automatically manages the operation of the two valves. The
system controls, also, fans operation in order to maximize the free cooling effect.
System changeover is controlled by embedded unit controller, depending on operating conditions and unit setpoint.
Between mechanical and freecooling operation the water side pressure drops are different, consequently the chiller water
flow could be different. Evaluate that the minimum and maximum water flow, between the two operations, are inside the
water flow limits (see product manual).
