Why does my Pentair AUTOTROL LOGIX 742 Control Unit show ERR 2?
If your Pentair Control Unit displays ERR 2, it indicates that the controller power doesn't match 50 or 60 Hz. To resolve this, try disconnecting and then reconnecting the power. If the problem persists, you may need to obtain a controller or AC transformer that is appropriate for your power frequency.
How to fix ERR 1 on a Pentair AUTOTROL LOGIX 742 Control Unit?
When the Pentair Control Unit displays ERR 1, it means the controller power has been connected, but the controller is unsure of its operating status. To fix this, reset the controller.
What to do if my Pentair AUTOTROL LOGIX 742 Control Unit will not draw brine?
If the Pentair Control Unit isn't drawing brine, several factors could be at play. First, check if the water pressure is low and adjust accordingly. A restricted drain line could also be the culprit, so remove any obstructions. Inspect the injector for blockages and clean the injector and screen. If the injector is defective, replace it along with the cap. Ensure valve disc 3 is closing properly by removing any foreign matter; if the disc is damaged, replace it. Lastly, check if the air check valve is prematurely closed; if so, momentarily put the controller into brine refill cycle. If needed, replace or repair the air check.
Why is my Pentair Control Unit leaking hard water after regeneration?
If you're experiencing hard water leakage after regeneration with your Pentair Control Unit, it could be due to several reasons. Start by checking the brine dosage setting and repeat the regeneration process. If you have an external bypass valve, check for leaks and replace if necessary. Inspect the O-ring around the riser pipe for damage and replace if needed. Finally, verify that the brine amount and system capacity are appropriate for your system.
Why am I running out of conditioned water between regenerations with my Pentair AUTOTROL LOGIX 742?
If you're running out of conditioned water between regenerations with your Pentair Control Unit, start by ensuring proper regeneration settings. Verify the brine setting is at the correct level. Also, confirm that the hardness and capacity settings are accurate. If your water hardness has increased, adjust the setting accordingly. Finally, check for any restrictions in the meter turbine rotation due to foreign matter; clean the turbine and flush with clean water, replacing the meter if necessary.
What causes brine tank overflow in a Pentair AUTOTROL LOGIX 742 and how to fix it?
If your Pentair Control Unit's brine tank is overflowing, several issues might be the cause. First, check for uncontrolled brine refill flow rate. Remove the brine controller to clean the ball and seat. Also, inspect the brine line for air leaks. Check all connections in the brine line. Finally, ensure that the drain control isn't clogged with resin or other debris and clean it if necessary.
How to stop brine tank overflow in my Pentair AUTOTROL LOGIX 742 Control Unit?
If the brine tank of your Pentair Control Unit is overflowing, it could be due to several reasons. Check if the brine valve disc 1 is being held open by foreign matter and manually operate the valve stem to flush away any obstructions. Inspect the brine line for air leaks, ensuring all connections are secure. Verify that the drain control is appropriate for the injector; a small drain control with a larger injector can reduce draw rates. Lastly, check for and clean any resin or debris clogging the drain control.
Why does my Pentair Control Unit regenerate at the wrong time of day?
If your Pentair Control Unit is regenerating at the wrong time of day, it's likely that the controller is set incorrectly. Correct the time setting according to the instructions.
What to do if there is no conditioned water after regeneration in my Pentair AUTOTROL LOGIX 742?
If you're not getting conditioned water after regeneration with your Pentair Control Unit, ensure there is brine in the brine tank by adding some. Also, check the injector for clogs and clean the injector and screen. If the air check valve closes prematurely, momentarily put the controller into the brine cycle. If needed, replace or repair the air check.
Why is there flowing or dripping water at the drain or brine line after regeneration in my Pentair AUTOTROL LOGIX 742?
If you notice water flowing or dripping at the drain or brine line after regeneration in your Pentair Control Unit, it might be because the valve stem return spring is weak; in this case, replace the spring. Another reason could be debris preventing the valve disc from closing properly, so remove any debris.
