WeatherguardThe Weather Guard takes the worry out of protecting your greenhouse and crop from wind, rain and snow. It overrides normal operations to close vents or retract shade systems when high winds, cold weather, rain or snow might cause damage. For example, if your STEP 50 wants to open the vents because it is hot and the WeatherGuard has detected high wind, then the vents will not open. The WeatherGuard system is different from the Weather Station. It does not monitor sunlight intensity or humidity. It overrides the environmental control’s decisions whereas the weather station shares information with the environmental control.

The Weather Guard is used with the following controls:

  • STEP Up
  • MiniSTEP
  • STEP 50
  • STEP 500
