GNordic Heating circulation pumps rotation indicator

• Very useful at start of heating season in order to check circulation pumps operation (checking of eventual pump blocking after longer non operation period)
• Also possible to provide oil burner solenoid valve operation checking
• The indicator is showing for most circulation pumps the magnetic field and the direction of rotation
• When the pump is running, the red / white screw will rotate in the same direction as the pump

Very useful at the start of the heating period to check the operation of the circulating pumps (check if the pumps are blocked after a long period of inactivity). Also possible to check the operation of the oil burner. With most circulating pumps, the display shows the magnetic field and the direction of rotation. When the pump is running, the red and white * rotates in the same direction as the pump.
