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.
40°C (at OUTSIDE AIR
temperature of 38°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: OFF, 1D / 90D)
TOPH. STOP Stop temperature for peak heating charging (applies to system VL). 60°C
(interval: 50°C / 65°C)
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 the ”Heat pump” section for
more information about Integral and Hysteresis.
60 (interval: 5 / 300)
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).
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)
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 Lowest outdoor temperature when the outdoor sensor stops the compressor
and heating or hot water instead produce with auxiliary heater.
-20°C
(interval: -20°C / -1°C)
SHUNT COOLING
(Expansion card)
Set point value for cooling. Desired temperature for supply pipe. 18°C (interval: 0°C / 30°C)
Sub menu SERVICE -> ADD. HEAT
Used to change the heat pump stage’s operating settings.
Menu selection Meaning Factory setting
INTEGRAL A2 Two conditions must be fulfilled in order to start the auxiliary heater: the inte-
gral’s value to start must be less than integral A1 + A2, and the supply tempera-
ture must be 2° lower than the calculated temperature. See figure 6 for further
information.
600 (interval: 50 / 990)
HYSTERESIS If the difference between the actual supply temperature and the calculated
supply temperature is too great (see figure 7), either the integral value is set to
start value A1 + A2 (the auxiliary heater starts) or the value is set to 0 (stops the
auxiliary heater ).
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 OFF can be select-
ed.)
2 (at OUTSIDE AIR 5)
(interval: OFF, 1 / 3)
(interval at OUTDSIDE
AIR: OFF, 1 / 5)
MAX CURRENT
(Expansion card)
Refers to main fuse in the unit, in amperes. 20 (interval: 16 / 35)
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).
60°C
(interval: 50°C / 65°C)
