The Fleck control valve is an electro mechanical valve that has wetted parts, electrical motors and micro switched and control timers. Fleck timers contain the regeneration information for when to begin regeneration, time of day to start, length of cycle time, and in the case of digital timers diagnostic and flow information.
The Fleck 3200 timer is the basic time clock timer that allows the user to select the day of regeneration and with the front time clock, the time of regeneration. This timer is available with a skipper wheel using sliding pins in a 12 #60304- or 7 #60303- day orientation. When the skipper pin is extended to the outside diameter of the wheel regeneration will occur that day. On the reverse side of the timer the program wheel with pins and holes determines the length and sequence of the regeneration cycle. Both timers are features in all service manuals.
The Fleck 3210 timer delayed regeneration responds to a mechanical gallon meter. The white dot above a number on the front label represents the number of gallons before regeneration. With the time clock on the front the unit will delay regeneration until that time is reached regardless of the gallons used after the trip point is reached. Both timers are features in all service manuals.
The Fleck 3220 timer immediate regeneration also responds to the mechanical gallon meter. As soon as the trip point is reached the unit will immediately enter regeneration. This timer has no timer clock face and is usually used in a twin alternating system.
The Fleck 3230 timer remote start requires an external signal to begin regeneration. Usually from a PLC controller or similar remote signal external to the control valve. Once signaled, the unit begins an immediate regeneration.
