This video will show you how to program your Aquatrol NX controller as a meter delay / immediate softener. This programming setup fits the following valve models as a Single Unit System:

AQT-275S-NX
AQT-285S-NX
AQT-290S-NX
AQT-315S-NX
AQT-385S-NX
AQT-390S-NX

The meter delay regeneration mode allows your system to regenerate at the day and hour after the system capacity zeros out. The meter immediate regeneration mode allows your system to regenerate immediately after the system capacity zeros out.

WARNING: We strongly suggest this maintenance be performed by a water treatment professional.

For more details about your valve, check the installation manual. You can download it here:
