CONTROL METHOD OF WATER SOFTENER

摘要

PROBLEM TO BE SOLVED: To perform regeneration operation at proper regeneration timing according to the hardness content in raw water. SOLUTION: This control method is a method for controlling a water softener 1 comprising a raw water line 2, a water softening means 3, and a treated water line 4. The regeneration timing of the water softening means 3 is controlled based on the detection value of a hardness detection means 9 installed in the raw water line 2 and the operation state of an apparatus 15 that uses soft water, installed in the treated water line 4.
