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 (hold key for autoscroll)
Press "P" again ...............parameter value appears
Use keys '
/
' ................adjust parameter value (hold key for autoscroll)
Press 'P' again ................value is stored, back to parameter no.
Unlock Keys / Access code
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. All other parameters must be unlocked as follows:
- enter access code before programming at parameter
P53
- directly at the parameter to be changed. If a code no. is necessary the
display shows "C00". Set the matching code no. by the "
/
"-keys (70 or
80, see parameter listing) and confirm by "P".
If no key is hit for about four minutes, the access code is cancelled and the
editing function is locked automatically.
Manual Defrost
While the actual value is visible:
- Press key "
" for more than 2 seconds = Defrost ON
- Press key "
" for more than 2 seconds = Defrost OFF.
Start-up behavior
Directly after start-up the display shows "810" (controller type), after that a
display test passes.
How to find out the controller type
- Press key "P" for > 2 sec. = Display shows controller type (
810
)
- Key "
" additionally = Software version is displayed
Manual controller "wake-up"
If the controller is switched off via interface (e.g. from a PC), the display shows
"
oFF
". By holding key "
" for > 3 sec. the controller unit engage.
Reset parameters to factory settings
Switch OFF supply voltage, press and hold "P"-key, switch supply voltage
ON again. Code request "C" appears. Enter "88", confirm by "P". One by
one software version, date and "def" appear. With this, all values are reset to
factory settings.
Changes of the -2 types in comparison to the older ones
- Different terminal assignment
- Error messages now as codes + error listing
- Unlock code entry now possible at each parameter
- Storage of the last actual value while defrost
- Emergency operation while sensor failures
- 3 new parameters, new codeparameter is (P53)
