English 4.1.3. OPERATING MODES The SysAqua units offer three operating modes: ²²Cooling mode = the unit cools the water circuit. The unit is regulated according to the water temperature sensor: If the measurement is less than the set-point: the unit is on stand-by If the measurement is above the…

SYSAQUA 15

Temperature control ensures that the water sensor selected by the client (EWT or LWT) attains the actual set-point, SP*. To manage the compressors more efficiently, the control uses the concepts of load and capacity. Load formulation The load is calculated via an algorithm PI minimizing the…
