Functioning
The controller operates in two modes:
Continuous
With the start of a rainfall the internal contact relay closes and remains closed for the entire duration
of rainfall. Combined with STR-3 and STR-4 roller blind controllers the continuous mode ensures closing of roller blinds at a time of rainfall and locking them in closed position until the end of rainfall.
Pulse
With the start of a rainfall the internal contact relay closes for approx. 1.5 second, passing to roller blind’s controllers a single command of closing. Combined with STR-3 and STR-4 roller blind controllers the pulse mode ensures closing of roller blinds at the time of rainfall, but then the user has the ability to raise the roller blinds at any time.
Selection of the operating mode is performed using the knob on the housing of the controller.
