the indoor.
During the execution of this test, the following screen is shown:
When the test starts, the user controller will exit from the installer mode.
User can cancel the test run regardless of the time le for test nishing.
The Test Run icon is shown in the notications zone, but the notication of this test run is taken

NOTE
• When commissioning and installing the unit, it is very important to use the “Air purge” function
to remove all the air in the water circuit. When the air purge function is running, the water pump
starts the automatic air venting routine which consists of regulating the speed and open/close
congured 3-way valve to help to evacuate air from the system.
• If there is a Heater or a Boiler installed, disable the operation before running the test run.
