If the average outdoor temperature (average 3 days) exceeds the value “End of heating“, the
heat pump switches to summer mode and heats only service water (if fitted). If the average
outdoor temperature is lower than the "End of Heating“, winter operation will be set and the
heat pump will maintain the specified room temperature (see chap. 3.2.4.1 on page 23).
3.1.9 Display, Fault Confirmation
If a malfunction occurs on the heat pump, the display will show in the upper right corner the
symbol ERROR and the character for the malfunction (P – malfunction of temperature sensors,
A – errors (alarms) of the system). Instead of room temperature, the two-digit number
indicating the fault index flashes. The fault must be confirmed by a short press of the rotary
button.
Press the rotary wheel 7 times in a row to enter the heat pump parameters. The
parameter input mode is indicated by a permanently lit symbol on the
display.
After entering the parameter input mode, the code of the entered parameter appears on the
display or a blinking symbol displaying a specific parameter (see Table 6). Rotating the wheel in
any direction changes both the parameter code and the precision symbol.
