To increase the service life of the appliance, a short-circuit monitoring mechanism
is installed in your heat pump. As a result, the compressor of the appliance may
sometimes start up with a short delay after the start of the heat pump. When this self-
defence mechanism activates, the small symbol shown in the picture flashes until the
compressor also starts up.
Anti-Legionella function
The anti-legionella function is designed to lower the risk of bacterial infection in the
tank, when it is not used for an extended period of time. After the installation and
start-up of the HPT300 appliance, the control system continuously monitors the water
temperature in it. The anti-Legionella function is accessible in all active modes. When
the appliance detects that the water temperature has not changed for a long time
in it (i.e. there is no water withdrawal), the control system automatically activates this
function, and heats the water above 60 °C.
The anti-Legionella function can be disabled in the Installation menu.
