ERROR DISPLAY (ER)
The codes only appear in service mode
When an error occurs, the lighting of the display will flash as well as the exclamation point; the
letters ER will be displayed and the error code.
There are 4 possible error codes:
RESET
There are two ways to reset. When this operation is done, it will be necessary to check all stages
of the programming.
- Partial reset: all parameters will be set back to default settings except remaining volume if the
valve is in volumetric mode and remaining days before the next regeneration in time clock mode.
In service mode, press simultaneously the buttons
and , until the valve displays:
- Total reset: all parameters will be automatically set to default settings. Unplug the unit, press
and maintain the button
while powering up the valve again; the valve will display :

Unplug the unit and examine the power head.
Check that:
- Everything is correctly connected to the circuit
board.
- The motor and gear are in good condition and
correctly assembled.
- Piston moves freely in the valve body.
Replace/re-assemble the different parts if
necessary. Connect back the unit and observe
its behavior. The valve should move to the next
cycle and stop there. If the error reappears,
unplug the valve and contact the technical
support.
Unplug the unit and examine the power head.
Check that everything is correctly connected to
the circuit board.
Enter the programming mode and verify that
valve and system types are properly set in the
system.
Initiate a manual regeneration and verify the
operation.
If the error reappears, unplug the valve and
contact the technical support.
Initiate a manual regeneration to remove
the error code. If it is a volumetric valve,
verify that the consumption of water is correctly
registered on the circuit board display. If there is
no counting, check the meter cable connection
and the meter functioning.
Enter the programming mode and verify that the
system is configured correctly; that the settings
match to the configuration of the valve, and that
the system capacity, and the day override are
set correctly, and that meter is correctly
identified.
Reset the programming and reconfigure the
system. After the programming, initiate a
manual regeneration. If the problem persists,
contact the technical support.
