Simple structure and reliable sealing
It adopts hermetic head faces with high degree pottery and corrosion resistance for opening and closing. It combines with Service, Backwash, Brine & Slow Rinse, Brine Refill and Fast Rinse.
Manual function
Realize regeneration immediately by pushing manual button at any time.
Long outage indicator
If outage overrides 3 days, the time of day indicator “?”will flash to remind the user to reset new time of day. The other set parameters do not need resetting. The process will continue to work after power on.
LED dynamic screen display
The stripe on dynamic screen flash, it indicates the control valve is in service, otherwise, it is in regeneration cycle.
Buttons lock
No operations to buttons on the controller within 1 minute, button lock indicator light on which represent buttons are locked. Before operation press and hold the “Up”and“Down” buttons for 5 seconds to unlock. This function can avoid incorrect operation.
Can be installed outside for F79 with weather cover.
With hard water bypass and no hard water bypass two choices.
No hard water bypass refers to the control valve no water pass when valve in regeneration. Model: A for no hard water bypass (No raw water flow out from outlet when in regeneration process); B for with hard water bypass. (With raw water flow out from outlet when in regeneration process)
With partial bypass function
When valve in service, by adjusting bypass screw can let part of raw water flow into the outlet without being softened.
Down-flow regeneration, up-flow regeneration and filter can be implemented with a valve.
By program selection to choose following modes
Mode | Name | Instruction |
A-01 | Down-flow regeneration，Meter delayed | Down-flow regeneration, regenerate on the day although the available volume of treated water drops to zero (0). Regeneration starts at the regeneration time. |
A-02 | Down-flow regeneration, Meter immediate | Down-flow regeneration, regenerate immediately when the available volume of treated water drops to zero (0). |
A-03 | Down-flow regeneration, Intelligent meter delayed | Down-flow regeneration, meter delayed regeneration type, but by setting resin volume, feed water hardness, regeneration factor, the controller will calculate the system capacity. |
A-04 | Down-flow regeneration by the day | Down-flow regeneration, regenerate when the service days reach to zero (0). |
A-05 | Down-flow regeneration by the hour | Down-flow regeneration, regenerate when time shows up zero (0). |
A-11 | Up-flow regeneration, Meter delayed | Up-flow regeneration, regenerate on the day although the available volume of treated water drops to zero (0). Regeneration starts at the regeneration time. |
A-12 | Up-flow regeneration, Meter immediate | Up-flow regeneration, regenerate when time shows up zero (0). |
A-13 | Up flow regeneration, intelligent meter delayed | Up flow regeneration, meter delayed regeneration type, but by setting resin volume, feed water hardness, regeneration factor, the controller will calculate the system capacity. |
A-14 | Up-flow regeneration by the day | Up-flow regeneration, regenerate when the service days reach to zero (0). |
A-15 | Up-flow regeneration by the hour | Up-flow regeneration, regenerate when time shows up zero (0). |
A-21 | Filter type | Filter type, filter when the service days reach to zero (0). |
Interval backwash times (Only suitable for up-flow regeneration type)
It could set up interval backwash times for up-flow type A-11, 12, 13, 14, 15, which means several times of services but one time of backwash. The setting of interval backwash time depends on the local water turbidity. (The lower the turbidity is, the longer of the interval backwash time can be set)
Rinsing frequence
It could set up rinsing frequency when selection of filter mode A-21, which means several times of backwash and fast rinse but one time of service (Need set). The brine line connector need to be sucked in this working mode, and the drain flow control should taken off.
