GRANT AERONA3 SMART OUTDOOR SENSOR

The Grant Aerona3 Smart Outdoor Sensor (part no. 103790) is an external temperature sensor designed to work with Grant Aerona3 air source heat pumps. By continuously measuring the outdoor air temperature, it enables weather-compensated control so the heat pump can automatically adjust flow temperatures for improved efficiency and consistent indoor comfort.

Purpose-built for the Aerona3 range, this accessory integrates with the system’s smart control logic to help reduce energy consumption, minimize cycling, and support stable, efficient operation across changing weather conditions.

Typical installation is on an external, shaded wall (ideally north-facing), away from direct sunlight and other heat sources. Professional installation is recommended to ensure correct placement and configuration with the Aerona3 controls.
