When homeowners consider installing a heat pump, the focus is usually on the unit itself. How efficient is it? How quiet is it? How sustainable is it?
But the real difference between an average heat pump system and an exceptional one isn’t just the heat pump, it’s how intelligently it is controlled. Smart controllers are the unseen technology that ensures a heat pump operates at its best, delivering comfort efficiently and consistently, whatever the weather.
This is where the award-winning Grant Aerona R290 air source heat pump and the Grant Aerona Smart Controller come together, creating a home heating system that is responsive, energy conscious and effortless to use.
Moving beyond basic heat pump control
Traditional heat pump controls act as simple interfaces. They allow homeowners to turn the systems on or off, adjust temperatures, and set basic heating schedules. While functional, these controls don’t actively adapt to changing outdoor temperatures, daily routines, or the heating needs of different rooms.

That is why smart controllers are so important. The Grant Aerona Smart Controller continuously monitors conditions and adjusts heat pump operation in real time. This means your home stays comfortable while the system works at peak efficiency, without you having to think about it.

What makes it smart?
The Aerona Smart Controller is designed for simplicity and control. Its sleek, 4.5-inch colour touchscreen replaces complex button-based systems with a clear, intuitive display. From one central interface, users can:
- Set heating schedules and domestic hot water timings.
- Adjust room temperatures to suit your lifestyle.
- Control multiple zones, ensuring different rooms are heated exactly as needed.
One of the standout features is weather compensation. By monitoring the outdoor temperature, the Aerona Smart Controller automatically adjusts the heat pump’s flow temperature. On milder days, the system runs at lower temperatures, saving energy while maintaining comfort. On colder days, it responds automatically, all without manual intervention.
With remote access via the Grant app, you can monitor and adjust your system from anywhere, giving you even greater control over comfort and energy use.
