Parameters
All selectable parameters hold a parameter number (e.g. P03), you will find
a listing on the next page.
Calling up and editing
Press key 'P' ........................................................parameter number appears
Use '/' ................................................................ select desired parameter
Press "P" again ........................................................parameter value appears
Use keys '/' ............................................................ adjust parameter value
Press 'P' again .................................... value is stored, back to parameter no.
Unlock Keys
To prevent un-authorized persons from editing parameter values, there is a
locking function which allows only the most important parameters to be changed
at any time. The access code can entered as follows:
- Before programming at P41
- Directly at the parameter to change. If a code is necessary, the display
shows "C". Use "/" to set the necessary code now and confirm by "P".
If no key is hit for about four minutes, the editing function is locked again.
Auto scrolling
Hold '/'-keys to scroll values automatically.
Manual Defrost
Manual defrost can be initiated while the display shows the actual value:
- Hold '' for more than 2 seconds = Defrost ON
- Hold '' for more than 2 seconds = Defrost OFF.
Reading the controller type
- Hold key 'P' for more than 2 seconds, the display shows controller type
(137 resp. 138, at TARN types h37 resp. h38). By pressing ""
additionally,
Set parameters to factory default (Init)
Switch off supply voltage, press and hold the 'P'-key, switch on supply voltage
again. Code request "C" appears. Enter "88" and confirm by "P". Now the
display shows one by one: software- version, date and 'def.', which signifies
that all parameters are set to default values now.
Error Messages / Error Listing
While a failure the display switches to parameter P40 and shows a code.
- Key "P" switches back to the last display
- If multiple failures are present simultaneously, codes can be read by
"/".
