Operator Level 2
Operator Level 2 provides access to additional parameters and this access is protected by
a security code. The Level 2 access should typically be granted to a specially trained
person, since changing parameters can have major impact on the temperature
performance of the furnace. After entering Level 2, press SCROLL
button to scroll
through the list of parameters. Like Level 1, the mnemonic of the parameter is shown in
the lower display, followed once by a scrolling help message showing a longer description
of the parameter. The value of the parameter is shown in the upper display.
Press DOWN or UP button to adjust this value. If no button is pressed for about
30 seconds, the display returns to ‘HOME Display’.
Back scroll is achieved when you are in the list by pressing UP button while holding
DOWN and SCROLL button.
To Enter Level 2
1. From any display press and hold PAGE button.
2. After a few seconds the display will show ‘LEv 1 GOTO’.
3. Release SCROLL button. (If no button is pressed for about 45 seconds the
display returns to the HOME Display).
4. Press the UP or DOWN button to choose LEv2 (Level 2).
5. Press UP or DOWN button to enter the password. The default code is ‘25’.
If an incorrect code is entered the display reverts to Level 1.
