The ‘Max Days Between Recharges’ is only available on select models. It allows you to choose the maximum number of days between recharge cycles.
What does it do?
By default, your softener’s algorithm will determine how often the system runs a recharge cycle. Since your water use fluctuates over time, so will the frequency of those recharge cycles. The Max Days feature is a programming tool that allows you to control how many days pass (at max) between recharge cycles.
This feature is used in special applications where it is beneficial to have a softener recharge more often than the algorithm calls for. For example, if you have high contaminant concentrations in your water, you may wish to override the algorithm and program your softener to run every few days in order to keep the system clean.
Your Max Days programming will override the algorithm if the algorithm frequency is longer. This means if the algorithm is triggering a recharge every 4 days, but you set your Max Days to 3 days, the max days will trump the algorithm. If this happens, the algorithm’s schedule will reset after the forced recharge and start counting 4 days again.
NOTE: There is no harm in running that softener on this feature, but note that these occasional forced recharge cycles may increase your salt and water use.
1. Hold Select until ‘000’ appears, then let go. Press the Program/Select button repeatedly to see if you have a screen that displays ‘Recharge’ and ‘Day’:
Max Days = "- - - -" or "Auto" – the softener will rely on the algorithm to calculate recharge frequency and salt dosage. This the most efficient option (pictured above).
Max Days = 6 or higher – the salt dosage during recharges will move up and down based on softening capacity used. This will result in average efficiency.
Max Days < 6 – the softener will likely switch between automatic recharges and forced recharges (based on your water usage). This may result in less efficiency.
