Get a good start
With the following procedure you can start regulation very quickly:
1. Open parameter r12 and stop the regulation (in a new and
not previously set unit, r12 will already be set to 0 which
means stopped regulation.)
2. Select application based on the wiring diagrams on pages 2-4
3. Open parameter o61 and set the application number
4. For network. Set the address in o03
5. Then select a set of presets from the "Food type" help table
6. Open parameter r89 and set the number for the array of
presettings. The few selected settings will now be transferred
to the menu.
7. Set the desired cut-out temperature r00
8. Select refrigerant via parameter o30
9. Set the pressure transmitter min. and max. range
10. Set the desired defrost method in d01
11. Set the interval time between defrost starts in d03
12. Set the desired defrost sensor in d10
13. Set the maximum defrost time in d04
14. Set the defrost stop temperature in d02
15. Open parameter r12 and start the regulation
16. Go through the survey of factory settings. The values in the
grey cells are changed according to your choice of settings.
Make any necessary changes in the respective parameters.
17 • Send address to system unit:
• MODBUS: Activate scan function in system unit
• If another data communication card is used in the controller:
- Lon RS485: Activate the function o04
- Ethernet: Use the MAC address
