How to programme the User Level Parameters of the Aerona³ Heat Pump Remote Controller

The Aerona³ Heat Pump Remote Controller should be fitted inside your customer’s home in a convenient location where it can be easily accessed. It provides access to a number of operating levels within the heat pump. The User level, Installer level and Service level access each contain their own set of parameter settings. While homeowners should be familiar with the User level, it is important that the parameter settings in both of the Installer and Service levels are only accessed and adjusted by a heating engineer or the installer.

The Aerona³ Remote Controller is used to switch the heat pump on or off, to display the room temperature, to display the outdoor temperature, to display the day and time, to access, check and adjust the Remote Controller’s parameters, and to access, check and adjust the heat pump control parameters. Error and fault codes will also display on the Remote Controller screen should there be a fault condition. It can also be used to view the heat pump’s operating conditions at any point in time using the Monitor Display function.

Here we explain how installers and engineers can access the User Level of the Aerona³ Remote Controller and how to view the parameter setting menu in the User Level.

Accessing the User Level

The User Level of the Aerona³ Remote Controller can be accessed by pressing and holding the ‘Menu’ button for three seconds. After the holding down the ‘Menu’ button for three seconds, the display will illuminate and the parameter number will display.

The ‘Menu’ button is button 3 on the diagram below. To help you identify the buttons on the Remote Controller, please refer to the diagram below and the key provided beneath.

Accessing, Checking and Setting the Parameters at User Level

During the commissioning of an Aerona³ air-to-water air source heat pump and at any other time when the parameter settings need to be checked or adjusted, engineers must refer to the relevant heat pump installation instructions. Provided below is step-by-step guide for the procedures to follow when you need to access, check and set the parameter setting at User Level:

1. Press the ‘Menu’ button on the remote controller for three seconds to enter the User Level.
2. The Parameter number “0000” and parameter value “----“ will be shown on the display.
3. The first two digits of the 4-digit parameter number (the parameter group number) will blink.
4. Set the parameter group number, as required, using the ‘Up’ or ‘Down’ buttons.
5. Press the ‘–‘ or ‘+’ buttons o to switch to the parameter code and the second two digits will blink.
6. Set the parameter code number, as required, using the ‘Up’ or ‘Down’ buttons.
7. Press ‘Set/Confirm’ button and the parameter value will be displayed. For ‘read-only’ items the number displayed remains on (rather than blinking) and pressing the ‘Set/Confirm’ button does not affect the
display.
8. If an invalid parameter (not accessible to the user) is entered and the ‘Set/Confirm’ button pressed, “---" is displayed. Press the ‘Return’ button to return to the parameter number.
9. If the parameter value can be adjusted it will blink.
10. Set the parameter to the required value using the ‘Up’ or ‘Down’ buttons.
11. Press the ‘Return’ or ‘Set/Confirm’ button. The parameter code number will blink to allow setting of another parameter, if required.
12. To return to normal operation, press and hold the ‘Menu’ button for three seconds, or simply leave the remote controller for ten minutes.
