The required time (minutes) where the T10 input must be higher than the E31 set point before
the heat pump starts in PV mode.
This parameter allows filtering of input power and avoidance of heat pump starts on short
spikes of excess PV power.
Options: 1-120 minutes
Factory setting: 15 minutes
Conversion of input signals to percentage used in
E30
and
E31
. Special cables are required for
0-10VDC and 4-20mA inputs.
E45: dT Air
Here the lowest desirable cooling of the air when the heating water is chosen. The control will
regulate the fan speed so that the air is cooled to the exact temperature that is selected. If
necessary for technical reasons, the controller can cool below the selected temperature. If
you want higher fan speed, the cooling temperature can be reduced. Note that too low delta
temperatures set points will force the fan to run faster with greater energy consumption as a
result.
Options: 1-15 °C
Factory setting: 3 °C
E46: Maximum water tank temperature
In order to avoid too high temperatures in the water tank when it is connected to a solar collec-
tor or another heat source, the max. allowable temperature in the water tank (T8) can be set.
This setting is used in menu point E19 .
Options: 40-70 °C
Factory setting: 60 °C
E48: Internal clock week day
Here the week day is set.
Options: 1-7 days
Factory setting: 1 day
