The device is intended for mounting on a wall in a vertical position without covering ventilation (leaving at least
15 cm from the bottom and the top).

taking them in place of the existing thermometer.
• We recommend setting the water heater thermostat at the maximum temperature position.
• Connect the PV modules to the Nectar Sun controller. Strictly observe the polarity.
• Plug in the Nectar Sun device to a grounded 230V power supply.
