The device is fitted with a standard connection cable. Before the start-up the connection cable must
be plugged into a socket with a voltage of 230V a.c.
After the cable has been plugged in, the starting sequence is shown on the display. The settings are
shown one after another.
If the starting sequence does not appear on the display, you must contact your customer service.

Heat Pump Operation
If the heat pump is properly connected to the voltage and water supply, the regulation version and the
operating programme set by the manufacturer (e.g. P.1) appear on the display after 2 seconds, as well
as all operational parameters and their values. 30 seconds after the device has been connected to the
mains, the entire system is activated and starts to heat the water. The heat pump operates until it
reaches the preset switch-off temperature (52
°
C) then it shuts-off automatically. When the water
temperature drops to 48
°
C, the heat pump switches automatically back on. The user can freely lower
or raise the switch-off temperature, the upper limit however is set to 55
°
C (regulator blockade). The
overheating of water is limited to 60°C and cannot be adjusted. The ambient air temperature at which
the system switches to the back-up heat source is set to 0
°
C, but can be adjusted by the user (see the
following instructions).
