     ELECTRICAL CHARACTERISTICS
     Output on single-pole relay in deviation.
     Contact rating 16(4)A 240 Vac.
     Power consumption 2W.

     REGULATIONS AND APPROVALS
     Compliant with EN60730-1, EN60730-2-9, EN55022 (CLASS B), EN50082-1.

     INSTALLATION
     Flush mounting (panel) with fixing brackets.

     OPERATION
     Type of control: can operate in ON/OFF or PID mode.
     ON/OFF control: in ON/OFF mode the output is ON or OFF depending on the input humidity, setpoint (1SP) and hysteresis value (1HY).
     The hysteresis indicates the amplitude of the deviation of the setpoint humidity to reactivate the output.
     PID control: in PID mode the output is ON for a fraction of cycle time 1CT.
     The cycle time characterises the dynamics of the system to be controlled and influences the accuracy of the control.
     Proportional control.
     Integrative proportional control.
