How can I program the PENTAIR OM34K OMNIFILTER softener control settings for optimal performance?

[IsabelaMarie]

Programming your PENTAIR OM34K OMNIFILTER High Efficiency Twin Tank Softener is straightforward. Here's a step-by-step guide:

1. Setting the Current Time:

   • The control initially displays 0 hours. Use the Time button to adjust the hour (0-23) to match the current time.

2. Setting the Recharge Time:

   • The softener recharges at 2:00 AM by default. To change this, adjust the clock setting to initiate the recharge at your preferred time.

3. Selecting the Salt Setting:

   • Press the Salt button to view the current setting (HC or HE). Press the Salt button again within 5 seconds to toggle between settings:
     • HC (High Capacity): Ideal for high water hardness or high water usage, maximizing the time between recharges.
     • HE (High Efficiency): Suitable for low water hardness or reduced water usage, conserving salt.

4. Entering Water Hardness:

   • Use the Hardness button to display the current hardness setting. Within 5 seconds, press the button repeatedly to increase the setting by 1 grain per gallon (GPG). Holding the button allows for rapid adjustment.

5. Completing the Programming:

   • Once the time, salt setting, and water hardness are configured, the programming is complete. The control unit will now operate according to your settings.

6. Important Considerations:

   • The system will automatically recharge if a recharge hasn't occurred in the past 7 days. During recharge, settings cannot be changed.
   • Ensure the unit is plugged into a continuous power source (non-switched outlet) for uninterrupted operation.
