Analogue Input Capacity Control
Analogue Input to Capacity control.
Analog Input 1 (DC 0 - 10 V)
SW501 bit-4(MCC-1777) OFF STEPPED response to analogue input
SW501 bit-4(MCC-1777) ON LINEAR response to analogue input
・To ease the integration of the Dx-coil with the DDC the capacity control is able to operate with a
STEPPED or LINEAR function from the analogue input.
・To select either a STEPPED(default) or LINEAR response, from the analogue input, use
SW501 bit4 located on the DDC(0-10V) interface P.C. board(MCC-1777)
AI4 Nothing Cannot be used.
Analog Input 2 (DC 0 - 10 V)
・ Capacity control signal(analogue input voltage) will be used as the main control value for the compressor frequency.
・ The control of capacity may not be able to be performed according to the state of an air-conditioner
(During oil recovercontrol, defrost etc.).
１）Capacity control 0-10V（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.
