What to Check / Before Buying
Ensure compatibility with your valve model (255, 278, etc) and the series of the controller you currently have.
Voltage / frequency: Make sure you order the correct version: 12 V, 50 Hz (Europe) vs other variants.
Symbols / labels: The description “with Symbol Label” suggests a version with pictogram overlay.
Since this part may be legacy or discontinued (some sites list “DISCONTINUED!!”).
Verify the programming features: setting time of day, days between regeneration, salt dosage, capacity. The manual shows “Salt Dosage” parameter.
If replacing, check that the rest of the control valve (top-plate, motor, cam, sensors) is in good condition so the controller works properly.
Check that the supply (transformer/12 V) and wiring harness is compatible with your setup.
