2.2 Displaying wind speed
When the display shows the temperature, briefly press the key once and the display will then change to
wind speed.
Briefly press the key again or wait approx. 60 seconds and the display will return to the temperature
display screen.
Wind speed can be displayed in both AUTOMATIC and MANUAL settings.
Note: The wind speed will not be displayed correctly for approx. 90 seconds after power has returned to the
weather station (e.g. after a loss of power or at start up). If the wind alarm is activated, manual operation is
blocked during this time.
2.3 Manual operation
The connected windows can be operated manually using the control panel keys.
AUTOMATIC operation is “switched off” and operation is no longer based on the indoor temperature.
The rain and wind alarms remain active if they are set to active in AUTOMATIC mode.
If the window is operated by using the (arrow keys), the system will revert back to AUTOMATIC operation
after 30 minutes.
If the key has been pressed for operating in (MANUAL operation), operation will remain in MANUAL
until the system has been returned to AUTOMATIC control by pressing the key.
Open stop close
The connected window can be operated manually using the , and (open, stop, close) keys.
With a short press of the key (shorter than 1 second), the window opens completely.
With a long press of the key (longer than 1 second) the window opens as long as the key is pressed.
With a short press of the key, the window closes completely.
With a long press of the key, the window closes as long as the key is pressed.
Pressing stops the window motor.
Manual/automatic
key switches between the AUTOMATIC and MANUAL operating modes. After manual operation
using the , or keys, the control system will be in MANUAL operating mode. Thus, AUTOMATIC
operation is deactivated and control is no longer based on the temperature. Pressing the key returns the
system to AUTOMATIC operating mode.

6
A long press of the key switches to the setting of values for AUTOMATIC operation and two long presses
switch to the setting of values in basic settings.
3. Setting values for AUTOMATIC operation

3.1 Indoor temperature
The first parameter that can be set is the indoor temperature, i.e. the interior temperature at which the window
shall open. The indoor temperature is pre-programmed to 25°C.
If the interior temperature is greater than this value the window will open, unless the outdoor temperature is
lower than the set lock-out value (3.2) or a wind or rain alarm is registered (points 3.3 and 3.4).
The indoor temperature has a hysteresis of 2°C, meaning the window will close again as soon as the indoor
temperature drops with more than 2°C below the set temperature.
The indoor temperature symbol blinks.
The value is set using , or select (found at +41°C and +4°C)
If is selected, the system will not be controlled by temperature, which is why setting the exterior
temperature lock-out (3.2) is skipped. The window can be operated manually and the wind and rain alarms are
active if they have been set to active in AUTOMATIC operation (points. 3.3 and 3.4)
Confirm the selection by pressing the key. The display will automatically change to setup for the next
parameter –outdoor temperature lock-out (point 3.2).
3.2 Outdoor temperature lock-out
The second parameter that can be set is the outdoor temperature lock-out. It is preset to 5°C.
The outdoor temperature lock-out is the temperature at which the window shall close if the temperature outside
falls below the selected temperature. The lock-out shall also hold the window closed to prevent energy loss,
even if the indoor temperature is exceeded.
The hysteresis of the outdoor temperature lock-out is 2°C, meaning opening of the window is only enabled
when the outdoor temperature is more than 2°C above the set temperature.

8
When the outdoor temperature symbol blinks, the value can be set using the keys or by selecting
(found at +21°C and -21°C)
If is selected, the "Outdoor temperature lock-out" will be turned off.
Confirm the selection by pressing the key. The display will automatically change to setup for the next
parameter –wind alarm (point 3.3).
The outdoor temperature lock-out should be set to a temperature above 0°C, if possible. If a window is opened
while temperatures are below 0°C, frozen rubber seals can get damaged.
3.3 Wind alarm
The third parameter to be selected is whether the wind alarm shall be ON (active) or OFF (not active).
An active wind alarm prevents the window from being damaged. The wind alarm is factory pre-set to 4 m/s.
If an active wind alarm is selected, the window closes if the wind sensor registers wind speeds greater than the
set value.
The window can still be operated using , but will return to AUTOMATIC operation after 2 minutes.
Table 3.3 can be used as a guide to finding the optimal value.
A wind alarm is maintained for 5 minutes. If the set wind value is exceeded by a new value during these 5
minutes, the period will begin again.
As long as a wind alarm is registered, the windsock symbol will be shown on the display.
RECOMMENDED SETTING; ACTIVE
If a non-active wind alarm is selected, the window will not close despite the high wind speeds.
When the wind alarm symbol blinks, the value can be set using the keys or by selecting (found at
21 m/s and 0 m/s).
If is selected, the "Wind alarm” is not activated.
Confirm the selection by pressing the key. The display will automatically change to setup for the next
parameter –rain alarm (point 3.4).

5. Safety information
In the event of a power failure to the weather station, the control unit can no longer control the connected
window motor!
The settings that are stored in the control panel are saved in the event of a power failure.
When the power returns, the controls go into AUTOMATIC operation.
If the radio connection between the control panel and the weather station is interrupted (e.g. if there are
disturbances with the radio connection or because the batteries in the control panel are empty), the window
cannot be operated manually. The system continues in AUTOMATIC operation without regard for the indoor
temperature until the radio connection is re-established. The wind and rain protection functions are maintained
if they were set to active before the power failure.
If it begins to rain, it may take some time before the weather station sounds the alarm, depending on the
outdoor temperature and the amount of rainwater. Closure time shall also be added for electrically powered
windows. Therefore, objects that are sensitive to moisture should not be placed in the area as they can be
damaged if water flows in.
Note that the windows, e.g. in the event of a power failure, do not automatically close if there is a rain alarm
unless an emergency power system is connected.
Safety instructions
Make sure that the window is in suitable condition for electric operation. It is recommended to grease
window hinges at least once a year after installation of the motor unit.
ATTENTION! To avoid personal injury during installation, do not connect motor to power supply until
installation is complete.
Electrically operated windows may cause personal injury if body parts are caught within the operating area
of the window. Where there is a risk of personal injury or a situation where children are involved, it is
recommended that the operation mode where the motor will run only as long as the keypad button/switch is
pressed be set to manual. In the automatic mode, because of the tractive capacity of the system, the risk of
personal injury will be increased. Never leave children in charge of window operation.
NV Solo®is a 24 V DC product and must not be connected to the mains voltage, as it thereby will be
damaged.
NV Solo®should not be fitted to a window, which is used for emergency escape/access.
Make sure that mains voltage is disconnected when cleaning or other maintenance/service of the window is
being undertaken, and ensure that it cannot be unintentionally reconnected.
Window actuators for smoke ventilation: If the window actuator has been exposed to temperatures above
90 °C it has to be checked by a WindowMaster technician.
The packing can be disposed of together with ordinary household waste. The product must be disposed of
in conformity with national regulations for electronic waste and not with usual household waste.
In case of technical problems, please contact WindowMaster, see telephone list.
