NCSP3 Functionality TestThe Body Control Module (BCM) should be wired correctly, withoutloose connections, and connected to 12 VDC at pin 90. A RED LED willindicate that the BCM is receiving 12 VDC.The 2 toggle switches on the BCM correspond to the 2 dialsunderneath them. (In the event where communication between theDisplay Commander (DC) and BCM is non-functioning, these switcheswill enable "manual" functions of the selected devices) The Leftswitch and knob are used for Electric Awnings and Jacks. (HydraulicJacks are manually controlled at the Hydraulic Pump. See theHydraulic Pump Manual Override in the RV owner's manual), and theRight switch and knob are used for Electric Slides 1 - 5.The BCM and DC communicate with each other through an RV-C (CANBUS) connection. This RV-C communication also allows the DC toconnect to a third party AC translator module (gateway) so that youcan perform the HVAC functions from the DC.The Display Commander (DC) will be mounted in an "all access" areanear the entrance. On the DC, press and release the Power button(the left button) to wake up the DC. After a moment, the PasscodeScreen will appear. Enter your Passcode. If this is the first time the DChas been powered on, an End User License Agreement (EULA) screenwill appear. Upon accepting the EULA, an “Enter New Passcode”screen will appear. Enter your new passcode and confirm.The DC will now bring up the Home Screen If the Floor Plan has beenloaded, all of the devices should be listed with correspondingactitation buttons

Go through all the functions and make sure they are operating properly. Allthe functions should be smooth and instantaneous. Ensure all the HomePage Hot keys actuate/turn on the corresponding functions.Cycle the Generator. When the Generator is being cycled for the firsttime (or if it has been a while since it has been used), it will need tobe primed. Hold the Prime button down to 2 -5 seconds, then pressand hold the Start button down until the generator starts.iN-Command is also equipped with an Auto Gen start. Press the“Manual” button to switch to “Auto” to activate the Auto Gen startfunction. If the battery voltage is less than 11.8V for 3 minutes, thesystem will start the generator. If the generator is started, thegenerator will run for 60 Minutes. Also, the system will attempt tostart the generator 3 times. If the generator fails to start after the 3rdattempt, the system will turn off the Auto feature and display a“Check Generator” Fault Message.HVAC TestingWhen testing the HVAC (Climate Function), make sure each “Zone” isdisplaying a room (Zone) temperature. Use the “Mode” button tocycle through Fan, Cool, Heat and Auto modes. (Heat and Automodes availability depend on the floor plan.)

Use the “Set” temperature up and down arrows to set the desiredtemperature. The “Set” temperature can be adjusted between 55 to 90F.Please review the NCSP3 User Manual for further HVAC operationalinstructions. You can scan the QR code shown below or use thefollowing link: wners-manual ncsp3.pdf

TroubleshootingHVAC (Dometic Systems) If the room temp reads 100F, remove the roomsensor cover and pull the room sensor out of the holding clip. Thetemp should read normally. Adjust the holding clip down on theroom sensor so that it is not pinching it.(RVP Systems) If the room temp reads 111F, the room sensor wasconnected to the cool shed connections on the RVP control box.Swap the wires between the cool shed and room sensor pins. Theroom temp should start reading correctly without a reset.(Both Systems)If no HVAC function, check to see if the room (zone)temp is blank. If it is, make sure the RV-C cables are connected tothe gateways and make sure there is an EOL (End of Line)terminator resistor at the last gateway in the line. Make sure theaddress on the gateway is correct. If that is correct, redo thepower, ground and communication wires between the gateway andcontrol box. Verify the gateway has proper 12VDC.(Dometic)If there are multiple rapid clinking sounds when operatingthe furnace function, the gateway has old software and needs to beswapped out.(Dometic)If a zone will not change functions (i.e. stuck on furnacemode), try adjusting the fan speed. Most likely it will show Auto, tryand get it to either low or high. This indicates the gateway is in alocked state. If you can get the fan mode to change, you shouldthen be able to change the zone function to off. Once it stays in offmode, power cycling the system.If changing an HVAC function in a Zone, and the function changes ina different zone, the dip switches are not set correctly. The front ACis Zone 1, middle is Zone 2 and rear is Zone 3.(RV-C) Communication issues Make sure the CAN-Low does not have a short to 12V.Make sure the CAN-High does not have a short to ground.Make sure there is not a short between CAN-Low and CAN-High.Check RV-C plugs and pins to make sure there is not a looseconnection. Try and power cycle all the components.Make sure the RV-C connector is pinned correctly.Try a different RV-C cable.Press the reset button on the BCM.If the generator or auxiliary fuel I/O’s from the BCM are connecteddirectly to 12VDC, all low current functions on the BCM will notoperate properly. I.E: The RV-C will not communicate properly andthe water tanks will not read correctly.No BCM Power Check if the Red Power indicator is lit.Press the reset button on the BCM.Verify 12V on Pin 90 and Ground on pin 86.Check Fuse in Main Breaker Box.Cycle RV Power at the Main Breaker Box.No DC Power Cycle power with the Power Button. (Press and hold thepower button for 5 seconds.)Verify 12V and Ground at the back of the DC.Verify no blown fuses in the Main Breaker Box.
