  • How can one test if a VR20 outside temp. sensor is working? If pressing the Red button on the rear of the module does not activate the flashing green light. is this an indication of faulty unit? The lens is clean. Solar sensor charging at around 2.1 volts. Battery is at 3volts. Submitted on 29-12-2021 at 16:45
