  • 3-digit 7-segment display.
  • 2 indicator LEDs of activated alarms “AL1 and AL2”.
  • WM44-P can be programmed in km/h or in MPH. P01
  • Selection between km/h and MPH at any time by pressing “SELECT”.
  • 2 indicator LEDs of working mode. km/h or MPH.
  • The alarm is triggered when the programmed value is reached or exceeded. An activation delay is included to prevent false alarms due to short gusts of wind.
  • An alarm is deactivated when the wind speed drops below the programmed threshold. A deactivation delay is also included.
  • Activation of ALARM2 deactivates ALARM1.
  • With ALARM2 activated the displayed wind speed blinks as a warning.
  • Alarm configurable characteristics: trigger values, polarity, intermittent or continuous operation, alarm latching (only ALARM2).
  • Alarm output: Relays. “ALARM1” contacts “NO” and “NC”, “ALARM2” contact “NO”. Voltage free relay contacts.
Wind speed sensors
FOR EXCLUSIVE USE with Anemo 4403 RF or Anemo 4403 RF BAT wind speed wireless sensor.
Analog output
4-20mA analog output proportional to displayed wind speed.
Preset user program
An alternate program configuration can be saved in memory. This preset configuration can be loaded at any time.
P00 - (3).
Minumum and Maximum wind speed registered values
WM44-P RF records automatically the Minimum and Maximum wind speed values. To see Minimum and Maximun values :
  • Lift up the frontal cover levering in the lower groove marked as “open to program”.
  • To visualize “Minimum” value, press ENTER button. To visualize “Maximum” value, press ENTER again. After 3 seconds, WM44-P RF will display the current wind speed.
  • To delete “Mínimum” and “Máximum” values press “ESCAPE” button during 2 seconds.


To access the programming push-buttons, insert a flat-head screwdriver into the groove marked as “open to program” and lever downwards to remove the front cover.

To enter program mode press “ENTER” and “ESCAPE” simultaneously for 2 seconds.

Button functions in program mode
Button Function
Up Increase program steps (P00,P01..), options or thresholds to program.
Down Decrease program steps, options or thresholds to program.
Enter Enters the program step currently displayed, validates options and values and exits programs step.
ESC Returns to program steps. Selects the digit to be modified within the range.


P00: (1) Exit program mode without saving data, (2) Exit program mode saving data , (3) Exit program mode loading “preset user configuration”data, (4) Pressing “ENTER” for more than 10 seconds, exit program mode saving data as “preset user configuration”.

  • Factory default values are enclosed in angle brackets “< >”.
  • Preconfigurated factory values in compliance with ITC MIE-AME-2 :
    • Wind speed sensor model: Anemo 4403 RF or Anemo 4403 RF BAT.
    • ALARM1 is triggered at 50km/h, ALARM1 activation closes the relay contact, ALARM1 is intermittent (ton=1sec, toff=5 sec).
    • ALARM2 is triggered at 70km/h. ALARM2 close contacts NO. ALARM2 is continuous.
  • Users may program WM44-P RF to comply with local saefty regulations.
