Check the possible behaviors in case the heat pump does not start heating right away:

  • At start-up, the appliance remains paused for about 30 seconds before it begins operating.

  • When the setpoint temperature is reached, the appliance stops heating — the water temperature is equal to or higher than the setpoint.

  • If the water flow rate is zero or insufficient, the appliance will stop. Check that water is circulating correctly through the appliance and that the hydraulic connections are properly installed.

  • The appliance will stop when the outdoor temperature falls below -12 °C.

  • The appliance may have detected an operating fault — check the error code on the display.
