Sub menu SERVICE -> HOT WATER
Used to change the settings for hot water production.
Menu selection Meaning Factory setting
START Start temperature for hot water production. Shows the actual hot water tem-
perature and the value within brackets indicates the start temperature.
(
= no sensor alarm)
40°C
(interval:
, 30°C / 55°C)
HOT WATER TIME Time for hot water production during combined hot water and heating demand,
in minutes.
40M (up to 8kW)
20M (10kW and more)
(interval: 5M / 40M)
HEATING TIME Time for hot water production during combined heating and hot water demand,
in minutes.
20M (interval: 5M / 40M)
TOPH. INTERVAL Time interval between peak heating charging, legionella function, in days. 7D
(interval:
, 1D / 90D)
TOPH. STOP Stop temperature for peak heating charging (applies to VL system). 60°C
(interval: 50°C / 65°C)
INFL. H.W SENSOR Water heater sensor’s influence compared with the peak sensor’s at start of
water heating.
65%
(interval: 0% / 100%)
WEIGHT HOT WATER The calculated value of the hot water sensor directed towards the peak sensor. -
Sub menu SERVICE -> HEATPUMP
Used to change the heat pump’s operating settings.
Menu selection Meaning Factory setting
INTEGRAL A1 The integral’s value for starting the heat pump. See section 12.9 for further infor-
mation.
60
(interval: 5 / 250)
HYSTERESIS If the difference between the actual supply temperature and the calculated sup-
ply temperature 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). See section 12.9
for further information.
10°C (at OUTSIDE AIR
temperature of 12°C)
(interval: 1°C / 15°C)
MAX RETURN Stop temperature at high return from the heating system. 55°C
(interval: 30°C / 70°C)
STARTINTERVAL Minimum tine interval between two heat pump starts in minutes. 20M
(interval: 10M / 30M)
ALARM BRINE Not shown if OUTSIDE AIR is selected as heat source. Alarm temperature for sup-
ply brine (brine out), which stops the heat pump. (
= no sensor alarm)
(interval: , -14°C /
10°C)
PRESSURE PIPE Sensor on the compressor’s hot gas line. Value within brackets indicates maxi-
mum permitted temperature. If this value is exceeded, the compressor will stop
and start again as soon as the temperature has dropped. No alarm shown in the
display, however, a square is shown in the left, lower corner of the display.
130°C
(interval: 100°C / 160°C)
OUTDOOR STOP Only appears if OUTSIDE AIR is selected. Lowest outdoor temperature when the
outdoor sensor stops the compressor and heating or hot water is instead pro-
duced with the auxiliary heater.
-20°C
(interval: -20°C / -1°C)
SHUNT COOLING
(Expansion card)
Set point value for cooling. Desired temperature for supply line. 18°C (interval: 0°C / 30°C)
