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
temperature according to a temperature value from the sensor.
Modules in a group operate in Standard control.
The module with the highest priority starts operating first, and if the module has the full
load, a module with the following priority will start operating.
When the module with the lowest priority operates at the minimum capacity and the
water outlet tmeperature reaches close to the set temperature, the compressors of the
module stop.
