What to do if my Ferroli Heat Pump unit is turned on but not heating or cooling as expected?
- J
  Jessica FryeAug 14, 2025
  If your Ferroli Heat Pump isn't heating or cooling as expected, there are several potential causes. First, the temperature setting might be incorrect; check the parameters T4HMAX, T4HMIN in heat mode, T4CMAX, T4CMIN in cool mode, and T4DHWMAX, T4DHWMIN in DHW mode. Second, the water flow could be too low; ensure all shut-off valves in the water circuit are in the correct position. Finally, the water volume in the installation might be insufficient; verify that it exceeds the minimum required value.

Why is my Ferroli OMNIA M 3.2 pump making noise (cavitation)?
- E
  Erik WhiteAug 17, 2025
  If the pump in your Ferroli Heat Pump is making noise (cavitation), it could be due to air in the system. In this case you should purge air. Alternatively, the water pressure at the pump inlet might be too low, so you should check the water pressure.

What to do if my Ferroli OMNIA M 3.2 Heat Pump has space heating capacity shortage at low outdoor temperatures?
- M
  Michael HoAug 21, 2025
  If you're experiencing a space heating capacity shortage with your Ferroli Heat Pump at low outdoor temperatures, it might be because the backup heater operation isn't activated. Check that the "OTHER HEATING SOURCE/ BACKUP HEATER" is enabled. Another potential cause is that too much heat pump capacity is being used for heating domestic hot water. In this case, check that the "t_DHWHP_MAX" and "t_DHWHP_RESTRICT" are configured appropriately.

What to do if the water pressure relief valve opens in my Ferroli OMNIA M 3.2 Heat Pump?
- M
  Matthew ArmstrongAug 25, 2025
  If the water pressure relief valve opens in your Ferroli Heat Pump, it could be that the expansion vessel is broken, so replace it. Alternatively, the filling water pressure in the installation might be higher than 0.3MPa. Make sure that the filling water pressure in the installation is about 0.10~0.20MPa.

What to do if the water pressure relief valve leaks in my Ferroli OMNIA M 3.2?
- J
  Joseph TapiaAug 29, 2025
  If the water pressure relief valve is leaking in your Ferroli Heat Pump, it's possible that dirt is blocking the water pressure relief valve outlet. Check for correct operation of the pressure relief valve by turning the red knob on the valve counter clockWise.

How to fix if heat mode can’t change to DHW mode immediately in Ferroli OMNIA M 3.2 Heat Pump?
- B
  Brittany Tran MDSep 2, 2025
  If the heat mode on your Ferroli Heat Pump can't change to DHW mode immediately, it might be because the volume of the tank is too small, and the location of the water temperature probe is not high enough. Set the maximum value and set WB'+'3B5(675,&7 to the minimum value.

Why Ferroli OMNIA M 3.2 unit is turned on but the compressor is not starting (space heating or domestic water heating)?
- M
  Michael JamesSep 5, 2025
  If your Ferroli Heat Pump's compressor isn't starting for space or domestic water heating, the unit may be operating outside of its operational range because the water temperature is too low. In this case, the system utilizes the backup heater to reach the minimum water temperature first (12°C).

How to fix if DHW mode can’t change to Heat mode immediately in Ferroli OMNIA M 3.2?
- J
  Joseph HernandezSep 9, 2025
  If the DHW mode on your Ferroli Heat Pump can't change to Heat mode immediately, it could be that the heat exchanger for space heating is not big enough. Set WB'+'3B0$; to the minimum value. Also, the space heating load may be small, which is normal, and no heating is needed.
