⚡ Easy DIY Troubleshooting & Common Fixes

🔧
Pressure switch does not turn on/off at the correct pressure. Setpoint varies.
prob_01
Common root cause: Incorrect adjustment of setpoints (pressure differential) or presence of air in the line.
Step-by-step solution: Verify that the pressure selectors (on/off) are correctly positioned. Ensure the water network is free of air by bleeding the system if necessary.
💡 Pro tip: After adjustment, observe the system's behavior for a few cycles to confirm the stability of the activation points.

⚙️ Hardware Setup, Adjustments & FAQs

❓ How to adjust the activation pressure (setpoint)? cfg_01
Turn the large selector to adjust the shut-off pressure (maximum) and the small selector to adjust the restart pressure (minimum). The difference between them is the pressure differential.
