How to fix 'STOPPED SYSTEM - HIGH PRESSURE' in Carel ROC025500N?
- C
  Courtney LyonsAug 9, 2025
  If your Carel Water Filtration System displays 'STOPPED SYSTEM - HIGH PRESSURE', it means the pressure switch downstream of the pump is measuring pressure exceeding 12 bar (only for ROC060). First, verify the pressure switch calibration and ensure the alarm corresponds to exceeding the 12 bar limit, which you can read from the manometer downstream of the pump. You can also adjust the pump bypass to lower the downstream pressure to between 5 and 10 bar. Additionally, you can set a delay of 5 seconds in menu 8C for reading the maximum pressure switch. If the issue continues, inspect the permeate pipe for obstructions and confirm that the produced flow is near the nominal value.

What to do if Carel Water Dispenser system stopped due to high pressure?

  If your Carel Water Dispenser system has stopped due to high pressure, it could be that the maximum pressure switch downstream of the pump is measuring a pressure higher than the set value of 12 bar (ONLY FOR ROC060). Verify the pressure switch calibration and confirm the alarm occurs when the set pressure is exceeded, using the manometer downstream of the pump to read the pressure. Act on the pump by-pass to reduce the pressure downstream of the pump to a suggested value between 5 and 10 bar. You can also set a delay in reading the maximum pressure switch (5 seconds) using menu 8C. If the problem continues, ensure the permeate pipe isn't blocked and that the produced flow is near the nominal value.

What to do if Carel Water Dispenser system stopped due to conductivity alarm?
- D

  If your Carel Water Dispenser system stops due to a conductivity alarm during production (ONLY FOR ROC060), there are several things to check. First, independently measure the conductivity of the produced water using an external conductivity meter. Also, ensure the machine's conductivity meter is working correctly; clean the head and recalibrate if needed. Examine the condition of the membranes and monitor their performance over time. Check the quality of the supply water, as output conductivity depends on it. Adjust the threshold value in menu 3B if it's too low. Increase the alarm delay in menu 3D, as water produced after inactivity may have higher conductivity. If you want to ignore the alarm, disable the Output Set Point in menu 3A.

How to check hi-level low-level contacts on Carel Water Dispenser?
- S
  Samantha MossSep 3, 2025
  To check the hi-level and low-level contacts on your Carel Water Dispenser, remember that the START authorisation is given by a minimum pressure switch (below 2 bar) or a float (low level). This signal is controlled by terminals 33-34. Verify that the START authorisation activates the signal, ensuring it's enabled in menu 5A, and use a tester to measure terminal continuity. Confirm the signal logic (NC/NO) matches the setting in menu 5B.STOP is triggered by a maximum pressure switch (at 4 bar) or a float (high level), controlled by terminals 22-23. Check that the STOP authorisation activates the signal, ensuring it's enabled in menu 6A, and use a tester to measure terminal continuity. Confirm the signal logic (NC/NO) matches the setting in menu 6B.

What to do if Carel ROC025500N Water Filtration Systems display 'STOPPED SYSTEM - LOW PRESSURE'?

  If your Carel Water Filtration System shows 'STOPPED SYSTEM - LOW PRESSURE', this indicates that the inlet minimum pressure switch is detecting feed water pressure below 0.8 bar for several attempts. You should: * Ensure the water supply pipe upstream has a diameter of at least 1/2".* Check that the supply water pressure is guaranteed while reading the inlet pressure on the manometer, considering both static (WTS off) and dynamic (WTS pump on) pressure.* If there's a pressurization pump upstream, verify its correct operation and, if needed, delay the WTS pump activation via menu 21A to allow the upstream pump to start.* Inspect the inlet filters for their condition and pressure loss using pressure gauges; replace cartridges and clean vessels if necessary.* Confirm the pressure sw...
