Temperature: max. ±0.5 °C of the measuring range (at 77 °F / 25 °C)
Measurement inputs pH and Redox/ORP via terminal mV
chlorine via CANopen bus
connection of sensor modules and actuator modules via CANopen bus
Control modes P/PI/PID control, intelligent control
Control Bidirectional control for pH (acid/alkali), unidirectional control for disinfectants
Eco!Mode Eco!Mode ‐ contact provides release for reduction of circulation power, provided DIN values are observed.
After completed reduction, the control parameters optimised for reduced operation can be activated.
