What to do if my Rotex Heat Pump shows a flow failure?
- L
  Lauren GutierrezAug 13, 2025
  If your Rotex Heat Pump is showing a flow failure, with water flow too low (less than 16 l/min) or no water flow, here are some things to check: * Ensure all shut-off valves in the water circuit are fully open. * Inspect and clean the water filter. * Remove any air from the system. * Verify sufficient water pressure using the manometer (pressure should be >0.3 bar when water is cold and >>0.3 bar when hot). * Confirm the pump speed setting is at its highest. * Check the expansion vessel for damage. * Ensure the water circuit's resistance isn't too high for the pump. * If the error occurs during defrost, check the backup heater power supply and fuses. Also, check the pump fuse (FU2) and PCB fuse (FU1).

What to do if my Rotex Heat Pump starts with a water temperature that is too low?
- T
  Terri HopkinsAug 21, 2025
  If your Rotex Heat Pump starts up outside its operation range due to low water temperature, the system uses the backup heater to reach a minimum of 15°C. Verify the backup heater power supply is correct. Check that the backup heater thermal fuse is closed, and the thermal protector is not activated. Also, ensure the backup heater contactors are not broken.

  Anne KhanAug 25, 2025
  If the backup heater in your Rotex Heat Pump isn't working, first check that the "backup heater operation status" field setting [4-00] is turned on. Next, check if the thermal protector of the backup heater has been activated and whether the thermal fuse of the backup heater is blown.

What if benefit kWh rate power supply settings and electrical connections don't match on my Rotex Heat Pump?
- M
  Michael FrySep 1, 2025
  If the benefit kWh rate power supply settings and electrical connections don't match on your Rotex Heat Pump, and if [D-01]=1 or 2, the wiring requires a specific installation. Other correctly installed configurations are possible but specific to the benefit kWh rate power supply type at your site.
