(the addition starts) or the value is set to 0 (stops the addition).
20°C (interval: 5°C / 30°C)
MAXSTEP Maximum number of permitted steps for auxiliary heating.
0 = no auxiliary heating permitted (Means that only AUTO or

SHUNTTIME Minimum time interval between signals to shunt motor to affect the supply tem-
perature, in seconds. Applies to all connected shunt groups (applies to system D
or VLD).
60S (interval: 10S / 99S)
HOT WATER STOP Stop temperature for hot water during ADD. HEAT operation (applies to the VL
system). The value is read off by the hot water sensor.
60°C
(interval: 50°C / 65°C)
Sub menu SERVICE -> MANUAL TEST
Used to manually test and test operate the heat pump’s components or signal outputs.
