2 Control logic
2.1 Turning on system
System starts to work then Main switch On/Off and Display/Comm On/Off both is in ON state.
2.2 Dry cooler control (Dry Cooler control)
Fan speed is regulated by output temperature of glycol. If temperature is closer to setpoint fan power is
increased.
Example. Setpoint = 20 °C, Dif = 5 °C. glycol temp. 15 °C fan power 0%, glycol temp. 17.5 °fan power 50%,
glycol temp. 20 °C fan power 100%.
