Sub-menu HOT WATER
Menu selection Meaning Factory setting
START Start temperature for hot water production. Shows the actual weighted hot water tem-
perature and the value within brackets indicates the start temperature. ( = no hot wa-
ter production)
(range: , 30°C /
55°C)
HOT WATER TIME Time for hot water production during combined hot water and heating demand, in mi-
nutes.
20M(range: 5M / 40M)
HEATING TIME Time for hot water production during combined heating and hot water demand, in mi-
nutes.
20M(range: 5M / 40M)
TOPH. INTERVAL Time interval between peak heating charging (anti-legionella function) in days. Operat-
ing mode that permits auxiliary heater must be selected.
7D(range: , 1D /
90D)
TOPH. TIME Time in hours that the legionella demand is to be fulfilled for legionella operation to be
considered complete.
(range: , 1M /
10M
TOPH. STOP Stop temperature for peak heat charging. Operating mode that permits auxiliary heater
must be selected.
60°C(range: 50°C /
65°C)
INFL. H.W SEN-
SOR.
Water heater sensor’s influence compared with the peak sensor’s at start of water heat-
ing.
65%(range: 0% / 100%)
WEIGHT HOT WA-
TER
The calculated value of the hot water sensor directed towards the peak sensor. -
9.2 Sub-menu HEAT PUMP
Menu selection Meaning Factory setting
INTEGRAL A1 The integral’s value for starting the heat pump. See Service instructions for more infor-
mation.
-60°min(range:
-250°min / -5°min)
HYSTERESIS If the difference between the actual supply temperature and the calculated supply tem-
perature is too great either the integral value is set to start value A1 (the heat pump
starts) or the value is set to 0 (stops the heat pump).
10°C(range: 1°C / 15°C)
MAX RETURN Stop temperature at high return from the heating system. 55°C(range: 30°C / 70°C)
START INTER-
VAL
Minimum time interval between two heat pump starts in minutes. 20M(range: 10M / 30M)
