What do the display symbols mean on my Aerona Remote Controller

The Aerona Remote Controller is a white cased unit designed to be wall mounted in a convenient location in your home. Unlike the Aerona Smart Controller, which is suitable for use with both the Aerona 290 and Aerona³ R32 heat pump ranges, the Aerona Remote Controller is only compatible with Aerona³ R32 air source heat pump models. 

Where is the Aerona Remote Controller display?

 The remote controller has a hinged front cover, behind which the LCD display screen is positioned with buttons situated to the right of the screen and beneath it. In the top right hand corner of the display screen, a series of symbols will indicate the operation and status of your Aerona³ heat pump.

Frost protection symbol

If this icon is displayed on the remote controller screen, it is indicating that the heat pump’s frost protection is active. Your Grant Aerona³ heat pump is fitted with automatic frost protection that will operate when either the outside air temperature or the system water temperature falls to or below a pre-set value (the factory default setting is 4°C).

Defrost cycle symbol

If this icon is displayed on the screen, it is indicating that the defrost cycle is active. You can read more about the how the defrost cycle works with Grant heat pumps here.

Heating demand symbol

If this icon is displayed on your remote controller’s screen, it is indicating a heating demand. If this is steadily displaying, it means the programmer and room thermostat are calling for heating. If the symbol is flashing, it is indicating that the heat pump is in heating mode but the heating has stopped due to a hot water demand that has priority. 

Hot water demand symbol

If this icon is displaying on the screen, it is indicating a hot water demand. If it is displayed, it means the programmer and cylinder thermostat are calling for hot water. 

Heat pump fan symbol

If this icon is showing on your remote controller’s screen, it is indicating that the heat pump fan is running. 

Circulating pump symbol

If this icon is displaying on the screen of the Aerona Remote Controller, this is indicating that the circulating pump in the heat pump is running.

Compressor symbol

If this icon is displaying on the screen, this is indicating that the heat pump compressor is running. If this symbol is flashing, it is indicating that the operation of the compressor is being delayed by the internal controls of the heat pump. This delay should normally stop after a short period and the compressor (and heat pump) will operate.
