Terminal AI3 / AI3: Analogue Input Capacity Control
• Be sure not input more than DC10 V in analogue input terminal.
• 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.
• Terminal AI4 / AI4 cannot be used.
