E19: Extra Function
If the set point is 1 the extra function will be activated as
soon as T9 reaches the setpoint (E2). If the set point is 0
the function will not be active. Set between 0-5.
0. The function is deactivated
1. The solar collector is activating the circulation pump
which is commanded from E2 and E20 and runs
independent from the heat pump (Only Vanvex RS).
2. The floor heat runs independed from the heat pump
which is commanded from E2 and E13 (Only Vanvex
RS).
3. The solar collector is activating the circulation pump
which is commanded from E2 and E20 and switch off
the heat pump. After the circulation pump has been
switch off it will take 30 minutes until the heat pump
again is activated (Only Vanvex RS).
4. The cooling function is activating a three way damper
which lead the cold air into needed rooms. It is
commanded from E2 and T9.
5. The mix function is activating a three way damper
which is mixing warm air with cold air. It is
commanded from E2 and T9.
Fabric setting: 0
E20: Solar col hyst (Only Vanvex RS)
If a solar collector has been connected, a temperature
difference may be set, this must be between the water
temperature in the solar collector (T9) and the operating
thermostat of the hot water tank (T8), before the
circulation pump of the solar collector is running.
The set point may be set between 0 - 5°C.
Factory setting: 5
E21: TX set
In order to avoid too high operating pressures in the
cooling system, the system output must be reduced for
the remaining part of the heating period. This parameter
indicates the water temperature at which the reduction
should start. It may be set to 0-55°C.
Factory setting: 45°C
E23: Tmop
This value indicates the maximum permitted evaporation
temperature. This prevents overloading of the cooling
system at high ambient temperatures.
Adjust this value between 0 - 30°C.
Factory setting: 25°C
E25: Vent level 2
If an extended period of extraction from the building is
wanted, it is possible to change to level 2. The fan will
now run, until another level has been selected. This
option is used to set the speed at which the fan should
run, when level 2 is selected. Please note that this setting
also sets the maximum fan speed when running in level
1. The speed may be set to 0-100%.
Factory setting: 100%
E26: Vent level 3
If extraction from the building at a specific length of time
is required, it is possible to change to level 3. The fan
will now run for the set period. Thereafter, the system will
return to level 2. This menu option is used to specify the
speed at which the fans should run when the set period
has been chosen. Please note that this setting also sets
the maximum fan speed when running in level 1. The
speed may be set to 0-100%.
Factory setting: 100%
E45: dTair-set
Here it is possible to choose minimum cooling of the air,
while heating the water. The control will adjust the speed
of the fan to make sure that the air will be cooled at the
exact temperature chosen. In case the control, due to
technical reasons, needs to cool the air, the value will be
controlled by the automatic function. When requiring a
higher fan speed, the value may be reduced. Remember
though, the fan will run faster, using more energy, if the
values are set to low. Set between 1-15°C.
Factory setting: 2°C
