Rotation control
DVM CHILLER's water outlet temperature is controlled according to the water outlet
temperature average value of all units which operates by pumps in a module. However,
if you set "Use" for an external water temperature sensor, it controls the water outlet
tmeperature according to a temperature value from the sensor.
Only one unit with the highest priority operates, and if the unit has the full load, a unit
with the following priority will operate.
The unit with the lowest priority operates at the minimum capacity, and if the water
outlet tmeperature reaches the set temperature, it performs On/Off control.
