The brine draw time (C2) can be viewed, but not changed in cycle time programming.
The brine draw time is changed with the salt setting and the brine draw rate.
The refill time (C8) can be viewed but not changed in cycle time programming.
The refill time is changed with the salt setting and the refill rate in the Level 2 programming.
REMARK : on 255 & Performa, Flappers / Cam position is identical on C2 and C3.
The value of cycle times stored for C2 and C3 are added so that the cam stays on position C2
/ C3 during the overall length of cycles C2 and C3.

Filter Mode

All cycle times including refill and brine draw may be programmed in minutes in filter mode.
