Energy saving and optimumoperation" on page 37.[2-12]= Enable the power consumption limitation via externalcontrol adaptor (DTA104A61/62)If the system needs to be running under powerconsumption limitation conditions when an externalsignal is sent to the unit, this setting should be changed.This setting will only be effective when the optionalexternal control adaptor (DTA104A61/62) is installed.Default value=1 (OFF).To activate this function change [2-12]=2 (ON).[2-20]= Manual additional refrigerant chargeFurther instructions regarding the different ways tocharge additional refrigerant into your system can befound in "16. Charging refrigerant" on page 31.Default value=1 (OFF).To activate this function change [2-20]=2 (ON).To stop the manual additional refrigerant chargeoperation (when the required additional refrigerantamount is charged), push BS3. If this function was notaborted by pushing BS3, the unit will stop its operationafter 30 minutes. If 30 minutes was not sufficient to addthe needed refrigerant amount, the function can bereactivated by changing the field setting again.[2-21]= Refrigerant recovery/vacuuming modeIn order to achieve a free pathway to reclaim refrigerantout of the system or to remove residual substances or tovacuum the system it is necessary to apply a settingwhich will open required valves in the refrigerant circuitso the reclaim of refrigerant or vacuuming process canbe done properly.Default value=1 (OFF).To activate function change [2-21]=2 (ON).To stop the refrigerant recovery/vacuuming mode, pushBS3. If BS3 is not pushed, the system will remain inrefrigerant recovery/vacuuming mode.Value[2-9] T c target (°C)1 413 436 46H1P H2P H3P H4P H5P H6P H7PON w x x x x c xOFF w x x x x x cH1P H2P H3P H4P H5P H6P H7PON w x x x x c xOFF w x x x x x cH1P H2P H3P H4P H5P H6P H7PON w x x x x c xOFF w x x x x x c[2-26]= Interlock (open) feedback on user interfaceThis setting is used to define whether you want toreceive feedback of the interlock or not. Indication is bydisplaying a malfunction code on the user interface. Ontop of that, the delay time by when a malfunction code isdisplayed on the user interface is selectable.Default value=0 (no feedback, no malfunction code onthe user interface).Change [2-26]=0, 1, 2, 3, 4, 5, 6 or 7 in function of therequired delay. In case a delay time is selected, themalfunction will be indicated on the user interface.[2-30]= Power consumption limitation level (step 1) via theexternal control adaptor (DTA104A61/62)If the system needs to be running under powerconsumption limitation conditions when an externalsignal is sent to the unit, this setting defines the levelpower consumption limitation that will be applied forstep1. The level is according to the table.Default value=2.Change [2-30]=1, 2, or 4 in function of requiredlimitation.[2-31]= Power consumption limitation level (step 2) via theexternal control adaptor (DTA104A61/62)If the system needs to be running under powerconsumption limitation conditions when an externalsignal is sent to the unit, this setting defines the levelpower consumption limitation that will be applied forstep2.
