4.20. SySTEM TESTInG
4.20.1. System start-up
After the installation of sensors and outputs, the
System Controller
controller can be started for the first time.
Switch on the mains power supply.
The controller will be initialised with the default configuration stored in the internal memory.
A test procedure is performed to check the validity of the data in the internal memory, and the various inputs are tested. All
sensors and communications devices are automatically detected. All faults and warnings are automatically reset and the
software version is displayed for reference.
4.20.2. SySTEM TEST
Once the system has been installed, it is recommended that the following tests are carried out:
Check that you have selected the correct configuration, and that the necessary installation parameters have been set.
1.
Check the wiring of the inputs and outputs. Use the procedure in 7.3 to view the temperature sensor values. Using the
2.
procedure in 4.20.4, it is possible to manually override the outputs to test the system operation.
Check that the Room Unit is communicating with the RF Receiver. To do this, change the temperature setpoint on the
3.
Room Unit to the maximum or minimum value and check that the heat pump reacts appropriately
