Page 4: System Description
ES 2050/51 System Description System Description The ES 2050 (wall mounted) and ES 2051 (panel mounted) controllers are designed for the monitoring and control of simplex (single exchange column) and duplex (twin exchange columns) water softener installations. Whilst a simplex installation can not provide softened water to service when the exchange column is in regeneration, a duplex installation is capable of providing treated water from one column whilst the other is being regenerated. -
