Page 4: System Description
System Description System Description The ES 2070 TV controller is designed for the monitoring and control of simplex (single exchange column), duplex (twin exchange columns) and triplex water softener installations. Whilst a simplex installation can not provide softened water to service when the exchange column is in regeneration, a duplex or triplex installation is capable of providing treated water from one ore two columns whilst the other is being regenerated. -
