In service, the time of day is viewed all the time. The valve operates normally until the pre-set number of days
since the last regeneration is reached. Once this occurs, regeneration will start immediately at the pre-set
regeneration time.
4.4.3 VALVE WITH REGENERATION DAY OVERRIDE
When the valve has reached its set days since regeneration override value, the regeneration will initiate
immediately or delayed at the pre-set regeneration time regardless of the volume remaining.
