How to access heat pump parameters using the Aerona Smart Controller?

Accessing the key operating parameters and settings for a Grant air source heat pump can be done quickly and easily via the Aerona Smart Controller and its touchscreen display.

Viewing heat pump parameters

To access the heat pump parameters, go to the main menu on the controller’s home screen and select the ‘settings’ icon which is displayed in the bottom lefthand corner (shown below). 

Next, select ‘Service Settings’ and enter the four digit password ‘1234’ and tap ‘enter’. This will take you to the heat pump parameters menu where you can scroll to find the relevant parameters or settings you want to view. 

Heat pump parameters

The heat pump parameters menu gives installers access to the following:

• Read only real-time values – including system status, primary flow and return temperatures, PWM feedback, water flow rate, compressor frequency, total power in, heating power out, total heating time, heating capacity, COP and more.
• Heat pump set points – including DHW set temperature, heating set temperatures for different zones, and room set temperature.
• Domestic Hot Water (DHW) – including DHW production type, maximum time for DHW, and minimum time for heating.
• Heat pump settings – including heat pump set points, zone control, DHW control, and controller type.
• Water pump settings – including heat pump water pump and external pump control.
• Frost protection – including frost room temperature, frost ambient temperature, frost flow temperature, and frost cylinder temperature.
• Back-up heater – such as back-up heater function, manual set point, integration time and condition for heater.
• Relay output settings – such as 3-way mixing valve, flow switch, night mode, modbus and more.

For a detailed list of the parameter settings, please refer to the Aerona Smart Heat Pump Controller manual. Please note, some parameters and settings are specific to the heat pump model installed so please refer to the Aerona 290 manual or Aerona³ R32 manual depending on the type of heat pump installed.
