When the wind sensor is disabled, during awning extension, the awning will stop 3 separate times. This is normal operation of the patio awning when the wind sensor is disabled.
To enable the wind sensor, depending on the generation of Weather Pro awning that you have, there will either be a wind sensor toggle switch of the side of the control box or you will need the wireless key fob remote. With the key fob remote, the instructions to enable or disable the wind sensor is located on the back.
