Electrical connections

Note: 2L and 3L must be connected to the same phase.

• Power connectors: wire size = 0.5 – 1.5 mm2, max. tightening torque = 0.4 Nm
• Low voltage signal connectors: wire size = 0.15 – 1.5 mm2, max. tightening torque = 0.2 Nm

Quick configuration at power-up

1. STEP 1: power on
2. STEP 2: select the quick configuration menu Within 30 seconds of power on, press “<” BACK for 3 seconds. The main switch “r12” is automatically set to OFF.
3. STEP 3: select pre-installed application o61 The display automatically shows the application selection parameter “o61” The digital inputs DI1 and DI2 can be configured for multiple functions (refer to Parameters “o02” and “o37”).
   NC = Not configured
   Press SET to select the pre-installed application. The display shows the default value (eg. “AP0” flashing). Choose the application type by pressing UP/DOWN and press SET to confirm. The controller presets parameter values according to the selected application and does not hide relevant parameters. Tip: you can easily move from AP0 to AP7, and thus select the simplified list of parameters, by pressing the UP key (circular list).
4. STEP 4: select sensor type “o06 The display automatically shows the sensor selection parameter “o06”. Press SET to select the sensor type. The display shows the default value (eg. “n10” flashing). Choose sensor type by pressing UP/DOWN (n5=NTC 5 K, n10=NTC 10 K, Ptc=PTC, Pt1=Pt1000) and press SET to confirm.
   Note: All sensors must be the same type.
5. STEP 5: configure DO2 output “o71”
   The display automatically shows the “o71” parameter to configure the “DO2” output. Select the required configuration (DEF or Lig or ALA) as per the application and press SET to confirm. The display returns to normal display mode and the control is started.

Quick Configuration via “cFg” Menu

1. Press the “SET” button for 3 seconds to access the parameter menu (display will show “cFg”).
2. Enter the “CFg” menu by pressing the “SET” button (display will show first parameter “r12” main switch.
3. Select “r12” by pressing “SET” button again and set the main switch to “oFF” (r12=0).
4. Press the back button (<) to come back to the ‘CFg” menu.
5. Press the DOWN button to scroll through the “cFg” menu parameter list.
6. Open the “061 application mode” and select the needed application mode (Press SET).
7. Open the “007 Cooling/Heating” and select the needed function and press”SET” (applicable only for APO and AP5).
8. Open the “006 Sensor type” and select the temperature sensor type used (n5=NTC 5 K, n10=NTC 10 K, Ptc=PTC, Pt1=Pt1000)- (Press “SET”).
9. Open the “071 DO2 configuration” and select the function associated to DO2 output and press “SET”.
10. Open the “002 DI1 Configuration” and select the function associated to digital input 1 (Press “SET”).
11. Open the “037 DI2 Configuration” and select the function associated to digital input 2 (Press “SET”).
12. Navigate back to parameter “r12 Main switch” and set it in “ON” position to start control.
13. Go through other parameters’ default settings and change wherever needed.
