Hydro Unit
Control
1)Capacity control (compressor, high-temperature release, low-temperature release)
This unit controls the compressor frequency and heater output so that the water outlet temperature matches the remote
controller set temperature.
1-1)Compressor control
Calculates the different between the remote controller set temperature (TSC_H, TSC_F) and the water outlet
temperature (Hot water supply: THO, Heating: TWO).
Sets the Hz signal correction amount that determines the number of compressor rotations by the temperature
difference.
Detects the number of compressor rotations.
Compares the Hz signal correction amount and the current operation Hz, and changes the compressor output
according to the difference.
* The control details are the same for hot water supply, heating, and cooling.
