1) Capacity control 0-10 V (Overview of capacity control)*
* There are possibilities of thermodynamic and/or mechanical limitation from many factors. which may affect our system's heat pump cycle
(refrigerant cycle) during operation. Hence, there is a possibility that the capacity output may be different from capacity control setting.
