Information screen 3 displays a list of values relating to the software used in the appliance as
shown in Figure 15. The most important of these values is the Software Ver. (meaning software
version). The example in Figure 15 displays the Software Ver. as 4.2.3a. It is beneficial to be
aware of the software version used on the appliance prior to seeking technical support.
Information screen 3 also displays the serial number of the appliance. The serial number cannot
be altered in the information screen shown in Figure 15. Instead, the serial number is configured
in the Engineer/Parameters sub-menu (See Commissioning Step 4 on Page 58). The serial
number displayed in the information screen should always match the serial number marked on
the label on the inside of the front casing door of the appliance.
The operating mode of the appliance varies through start-up, modulation and shut down, and
can be seen changing when viewing information screen 1 (see Figure 13). Further explanation
of each operating mode is given in Table 4.
