1. Description
The NV Solo® weather station can automatically control opening and closing of windows in a room (a zone) in
order to achieve the desired indoor climate.
AUTOMATIC operation
Opens the window at the selected indoor temperature
Closes the window if the temperature falls below the selected outdoor temperature (outdoor temperature
lock-out)
Opens the window to the selected preset position (LEAPOS)
Or the window opens modulated (selected opening time (LEASP))
Closes the window at a selected wind speed (wind alarm, optional)
Closes the window if it rains (rain alarm, optional)
The window closes when the temperature falls below the set indoor temperature or if a rain or wind alarm is
registered.
MANUAL operation;
The windows are operated manually using the control panel.
The wind and rain alarm is active, if it has been activated under AUTOMATIC operation.
1.1 Delivery
NV Solo® is comprised of a weather station and a control panel with 2 x 1.5V AA/LR6 batteries.
1.2 Start-up
Installation, testing and start-up of the window motor and the control unit are performed in
compliance with applicable national legislation.
1. Setting values for basic settings (see point.4)
2. Setting values for automatic operation (see point.3)
3. Installation and connection (see points 6 & 7)
1.3 Connection
NV Solo® is connected to WindowMaster WUC or WCC control units by Natural Ventilation or WSC compact
smoke panels for fire ventilation.

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
In order to achieve optimal ventilation, the values in AUTOMATIC operation must be adapted to the building
conditions.
Press the key on the control panel for at least 3 seconds to get to the programming of values for
AUTOMATIC operation.
When the two symbols and are shown on the left of the display, the values can be changed (points 3.1 to
3.5).
If the programming setting is exited by pressing the key or if the keys are not activated within 5 minutes, the
programming setting will be exited and the entered settings will not be saved.

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).

3.4. Rain alarm
The fourth parameter that can be set is whether the rain alarm shall be active or not active .
An active rain alarm prevents water penetration. The rain alarm is pre-programmed to be active.
In active, the window closes if the rain sensor registers rain.
The window can still be operated using , but will return to AUTOMATIC operation after 2 minutes.
A rain alarm is maintained for 5 minutes. If precipitation is detected again during these 5 minutes, the period
starts over again.
As long as a rain alarm is registered, the umbrella symbol will be shown on the display.
RECOMMENDED SETTING; ACTIVE
If a non-active alarm is selected, the window will not close even if it rains.
When the rain alarm blinks, select whether the alarm shall be active ( ) or non-active ( )
Using , select between and .
Confirm the choice by pressing the key. The display will automatically change to setup for the next
parameter – save the values (point 3.5).

3.5 Save the values SAV
Once the values in points 3.1-3.4 have been set, save the values (SAV=save) by pressing the key, and the
display returns automatically to the indoor and outdoor temperatures.
If is pressed here, you will exit SAV without saving the values.
