For connection of rain sensor.
Connection of wind / rain sensors type WLA 330 or rain sensor WLA 331.
Data
9.1 24V
9.2 Rain (potential free / dry contact) (10kΩ resistor is to be moved to the
Rain sensor)
9.3 GND / 0V
With the default values are input:
”Active” if the contact resistance is smaller than 4kΩ
”Inactive” if the contact resistance is bigger than 8kΩ.
For values between 4 and 8kΩ the result will depend on the supply voltage.
Input has pull up 17pprox.. 1mA. (min. 0.7mA, max 1.4mA)
Example: Wind/rain and rain sensors
WLA 330 and WLA 331– the settings of the sensors are set on the sensor.
Connection for power supply
USB device. Used for remote control and update of firmware
Connection for battery (power back-up)
Reset / Programming (used for firmware updates)
DIP switch blocks with 8 DIP switches
1 – No 230V window position unchanged
2 – Momentary action open / close
3 – Re-triggering by alarm (VdS)
4 – Close on Smoke detector
5 – Open / close on fire
6 – Limited opening comfort ventilation
7 – Time comfort ventilation
8 – Pyrotechnic gas generator
See section 11 for further detail
Shows the status of the panel
Red = alarm
Yellow = fault
Green fast flickering = all OK (CPU working), Green constant = CPU communication stopped (possible reset or
contact WindowMaster)
Close / open all windows. When pressed together right after power has been connected the panel configures /
registers connected components.
