4. Depress the black TIME SET button. The numbers will roll from “0” to “15.” 

Release the switch at the desired number of days for the calendar override. For 
example, releasing the switch at “10” would program a 10-day calendar 
override.

5. Disconnect power.
6. Place jumper back on TIME and reconnect power.
7. The calendar override program is maintained during power outages by the 

NOVRAM circuitry.

8. To remove the calendar override, follow the same steps above and program 

back to “0.”

When using the 255 valve with the 440i or 460i controls, there are several 
features and procedures that are unique to the 400 series controls. They are as 
follows:

These models may be adjusted to produce maximum to minimum conditioning 
capacities by setting the salt dial, which controls the amount of salt used per 
regeneration. When desired, the minimum setting may be used on installations if 
the frequency of regeneration is increased to compensate for lower regenerated 
conditioning capacity. The installing dealer will set the unit for proper salt usage. 
Further adjustments are needed only if the hardness of the water supply changes 
or if water use changes dramatically. Capacity will need to be adjusted 
accordingly.

To adjust salt dosage, insert a small screwdriver into the white indicator knob and 
move pointer to proper salt setting (Figure 13). 

To convert the salt settings from English to metric, divide by 2.2 (e.g., 12 

pounds 

÷ 2.2 = 5.5 kg of salt).
