Page 4: System Description
System Description System Description The ES 2070 SV controller is designed for the monitoring and control of simplex (single exchange column), 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 columns whilst the other is being regenerated. -

Page 26: Time Controlled Regeneration
ES2070 SV Setting and changing of initial values 4. Time controlled regeneration Step nr: Interim startY/N Regeneration can be initiated at fixed time intervals. This operating mode is selected if a water meter is not desired either because the water usage is regular and predictable or for operational reasons. Sometimes this mode of operation is selected where there is a danger of micro organism formation within the unit due to a prolonged standby period. -

ES2070 SV Setting and changing of initial values 5. Minimum time between regeneration’s. Step nr: Min.reg.time Based on the capacity of the installation, the incoming water hardness and flow rate, the minimum time between two regeneration cycles can be calculated. With installations utilising brine tanks it may be necessary to allow time for full strength brine to be produced, the actual time will depend upon the type of brine system used but could exceed 4 hours. -
