Why Clack Water Specialist WS1CS Control Unit does not regenerate automatically but does when REGEN button is depressed?
- P
  Peter StevensAug 15, 2025
  If your Clack Control Unit regenerates when the REGEN button is pressed, but not automatically, it could be due to: * The bypass valve is in the bypass position. * The meter connection is disconnected. * The meter turbine is restricted or stalled. * The meter is defective. * The PC board is defective. * A set-up error. To address this, put the bypass valve in the normal operation position, connect the meter to the PC board, remove the meter and check for rotation or foreign material, replace the meter, replace the PC board, and check the control valve set-up procedure.

  If your Clack Control Unit is regenerating at the wrong time of day, it could be due to: * Power outages. * The time of day not being set correctly. * The time of regeneration being incorrect. * The control valve being set at “on 0” (immediate regeneration). * The control valve being set at NORMAL + on 0. To resolve this, if the power outage lasted more than 8 hours, reset the time of day. If it was less than 8 hours, reset the time of day and replace the battery. Reset the time of day to the correct time, and reset the regeneration time. Check the control valve set-up procedure regeneration time option.
