Step 5CS
Select OFF when none of these features are used.
Only use Watts No Hard Water Bypass Valves or Watts Motorized Alternating Valves (MAV) with these selections. Watts No Hard Water
Bypass Valves (1" or 1.25" V3070FF or V3070FM) are not designed to be used with the alternator or separate source functions.
Configuring the Control Valve for No Hard Water Bypass Operation:
Select nHbP for control operation. For no hard water bypass operation the three wire communication
cable is not used.
Selection requires that a connection to MAV or a No Hard Water Bypass Valve is made to the two pin
connector labeled MAV located on the printed circuit board. If using a MAV, the A port of the MAV must
be plugged and the valve outlet connected to the B port. When set to nHbP the MAV will be driven
closed before the first regeneration cycle that is not FILL or SOFTENING or FILTERING, and be driven
open after the last regeneration cycle that is not FILL.
NOTICE
If the control valve enters into an error state during regeneration mode, the no hard water bypass valve
will return to the open Position, if not already there.
Configuring the Control Valve for Separate Source Operation:
Select SEPS for control operation. For separate source operation the three wire communication cable is
not used.
Selection requires that a connection to a Watts Motorized Alternator Valve (MAV) is made to the two pin
connector labeled MAV located on the printed circuit board. The C port of the MAV must be connected
to the valve inlet and the A port connected to the separate source used during regeneration. The B port
must be connected to the feed water supply.
When set to SEPS the MAV will be driven closed before the first regeneration cycle, and be driven open
after the last regeneration cycle.
NOTICE
If the control valve enters into an error state during regeneration mode, the MAV will return to the open
position, if not already there.
Selecting the Control Valve to act as an alternator:
519.0 and higher = Use 3-wire Interconnect Cables for all communication between units.
518.3 and lower = Use 2-wire Interconnect Cables for twin alternators with independent flow meters.
Prior to starting the programming steps, connect the communication cable to each control valve board's three pin connector
labeled 'COMM CABLE'. Also connect the meter cord to either control valve to the three pin connector labeled 'METER'.

If set up for a filter, in Step 5F set Volume Capacity in Gallons; in Step 6F select Regeneration Time Option "on 0"; and in Step 3I select
Day Override "oFF".
NOTICE
If the control valve is in an error state during regeneration mode the MAV will close the B port and keep open the A port until the error is
corrected and reset.

This display will not appear if 1.0 was selected in Step
2CS. Allows selection of one of the following using or :
• the Control Valve to have no hard water bypass;
• the Control Valve to act as an alternator;
• the Control Valve to have a separate source during the regeneration
cycle; or
• the Control Valve to operate with the System Controller.
