The Grant Aerona3 Smart Controller Wi-Fi Hub is a device designed to enable remote control and monitoring of a Grant Aerona3 heat pump system. The Aerona3 is a range of air-source heat pumps made by Grant, commonly used for heating and hot water in homes.

The Wi-Fi Hub serves as the central connection point that links the Aerona3 heat pump to your home’s Wi-Fi network, allowing homeowners to control and monitor the heat pump via an internet-enabled device like a smartphone or tablet. This remote access can be especially useful for adjusting settings or troubleshooting without needing to be physically present at the location of the unit.
