INSTALLATION INSTRUCTIONS

REPLACING BATTERIES
Before using a battery other than that which was installed at the caravan dealership, consult with the battery manufacturer for a detailed description of the installation, uses, and maintenance of the battery. Verify that the type and capacity of the battery or batteries used are compatible for use with the J35.
Figure 3 details the connection of the caravan battery to the J35.
After fitting a new battery to the J35, make sure that it is configured in the JHub App.
Correctly configuring the battery capacity and profile will ensure that the J35 will select the best charging parameters for the caravan battery in use, and the software accurately estimates battery usage.
Sparks have the potential to cause an explosion should combustible gases be present. The following procedures are designed to minimize the risk of spark generation when connecting or disconnecting the battery. The positive terminal of the battery must not be connected to the chassis.
Do not install the battery in the same compartment where flammable material, such as petrol, is stored.

Figure 3: Wiring the caravan house battery to the J35. To protect against short-circuits and reversed battery connections, install a 40A fuse, as close as possible to the battery’s positive terminal.
DISCONNECTING A BATTERY FROM THE J35
To disconnect a battery from the J35:

1. Power off all loads connected to the J35, the easiest way is with the switch connected to the J35 Load Isolation input
2. Turn off and remove all power sources (mains/solar/AUX) to the J35
3. Disconnect the battery’s negative (black) terminal from the J35 Batt- connection point
4. Disconnect the battery’s positive (red) terminal from the J35 Batt+ connection point

CONNECTING A BATTERY TO THE J35

1. Of the same type, for example, deep cycle AGM battery
2. Of the same capacity, for example, 100Ah
3. By the same manufacturer
4. Fully charged
5. Of the same age-never use batteries that differ in age

The recommended wiring for connecting multiple batteries in parallel to the J35 is given in Figure 4. Depending on system requirements, a qualified auto-electrician may wire the batteries differently.

Figure 4: Recommended wiring for connecting batteries in parallel.

USING YOUR J35

BATTERY CHARGING AND MANAGEMENT WITH THE J35
Input Power Sources
The J35 may be powered from mains, AUX, or solar inputs to provide battery charging current and power to caravan loads.
If mains and one or more other sources are available to the J35, the J35 will be powered exclusively by the mains source.
If both AUX and solar inputs are available and the mains is not, the J35 will draw power from both the AUX and solar inputs. As full charge approaches, one of these sources may dominate the other as appropriate.
Battery Charging
The J35 can simultaneously deliver up to 20A (J35A) or 35A (J35B, J35C, J35D) to the caravan battery and loads from the mains input source, with a maximum charging current of 15A. The maximum charging current is boosted to 30A in the J35D.
The maximum charging current will be reduced if loads are drawing significant current and as the battery approaches full charge. To ensure that the caravan battery is charged by the maximum charging current, switch off non-essential loads.
When charging the battery from the mains, the J35 applies a multi-stage charging process. F
or charging from AUX and/or solar sources, the J35 monitors the battery voltage level and charges as needed.
Battery Health Preservation
The J35 preserves battery health by preventing the battery from excessive discharge. The J35 will start a two-stage shutdown or Low Voltage Disconnect (LVD), powering down all J35 outputs except for Air Suspension. This is to conserve the remaining battery capacity until the battery can be charged.
Air Suspension output is not affected by LVD and will remain operational throughout. The remaining battery capacity will drain quickly if Air Suspension is engaged while the J35 is in LVD.

Table 6: LVD Mode voltage thresholds
The J35 will enter the two stages of LVD, Sleep Mode and Storage Mode, when the caravan’s battery voltage falls below the LVD thresholds.
SLEEP MODE
The J35 will provide power to the CAN bus. This allows you to continue to monitor battery consumption from the battery monitor. However, power to the load terminal block will be turned off and you will not be able to use your battery monitor to power caravan loads.
To exit Sleep Mode, start battery charging. The J35 will exit Sleep Mode when the battery is sufficiently charged. Upon exit of Sleep Mode, the J35 will automatically return to its previous state of operation.
When in Sleep Mode you may temporarily turn on caravan loads by cycling the caravan’s Load Isolation Switch. This feature allows you to retract slide-outs or electric steps should you need to pack your caravan. This temporary switch- on of the caravan loads may also be done by pressing the Battery icon on your battery monitor.
STORAGE MODE
Power to the CAN bus will now be turned off; meaning no communication or power to the accessories connected to the J35 CAN bus. Please note, that the JHub Tablet (if in use) may run on its internal battery for some time.
To exit Storage Mode, start battery charging. The J35 will exit Storage Mode when the battery is sufficiently charged. Upon exit of Storage Mode, the J35 will not automatically return to its previous state of operation; caravan loads will need to be powered on manually.
When in Storage Mode you may temporarily turn on caravan loads by cycling the caravan’s Load Isolation Switch.
Heavily Discharged Batteries (Lead Acid)
The J35 will not charge heavily discharged lead-acid batteries.
In normal use, and with the J35 battery health preservation, batteries should never become heavily discharged.
If your battery is heavily discharged, disconnect it from the J35 and charge with a stand-alone charger. Reconnect the battery once the battery voltage has recovered to normal levels.
Heavily Discharged Batteries (LiFePO4) (J35 Model D only)
The J35D can recover and charge a heavily discharged LiFePO4 battery. The internal Battery Management System (BMS) of a LiFePO4 battery will turn off if it detects that the battery is heavily discharged. The J35D will provide the voltage to restart the LiFePO4 battery’s BMS and then commence charging of the LiFePO4 battery.
USING THE J35 AS A POWER SUPPLY (BATTERY-LESS OPERATION)
The J35 will act as a power supply if the following conditions are met:

1. A battery is not connected to the J35, and
2. The J35 is connected and powered by mains, or
3. The J35 is connected and powered by AUX input

Power Supply mode allows you to control and power your caravan’s loads directly from mains or AUX without the need to connect the caravan battery. When powered from the mains, the J35 provides an output voltage of 12.8V. When powered from an AUX input, the output voltage will vary depending on the AUX input voltage.
FAULT PROTECTION
Overload or Short Circuit Protection
If an overload or short circuit is detected, the affected output will shut down. The J35 will automatically attempt to restart the output every 30 seconds until the fault is removed.
Over-Voltage or High Internal Temperature Protection
If an over-voltage or high internal temperatures are detected the J35 will automatically turn off. Once the over-voltage is rectified, or the internal temperature drops to normal levels, the J35 may be restarted by cycling the mains input on and off.
Reverse Battery Protection
The J35 Battery fuse and fuse fitted by your Jayco dealership at the battery protects from accidentally connecting the battery to the J35 in reverse polarity.

PAIRING WITH THE CONTROL NODE

To pair the ControlNode to your own personal mobile device:

1. Make sure that the Control Node is connected to the J35 and that the J35 is powered on.
2. Turn on Bluetooth on your own personal device
3. Press the Pairing Button on the Control Node. The LED Status Indicator on the ControlNode will flash green, indicating you have 30 seconds to pair to the Control Node.
4. Launch the JHub App and press scan at the prompt.
5. The JHub App will now search for nearby ControlNode devices and a pop-up window will appear listing ControlNode devices available for connection.
6. Select the device with the number that corresponds to the last six digits of the serial number of the Control Node you wish to pair to.

For successful pairing, the LED Status Indicator on the ControlNode will turn off and the Bluetooth Connectivity icon in the JHub App will turn blue.
A Control Node can simultaneously pair to five mobile devices (including the JHub Tablet). If the Control Node is already paired to and in Bluetooth range with five mobile devices, the LED Status Indicator on the ControlNode will flash orange for one second.
Press and hold the Pairing Button on the ControlNode for 10 seconds until the LED flashes red. This will clear the ControlNode memory of any connected devices. The Control Node will then automatically flash green to indicate that it’s ready to pair with a new mobile device.
When you clear the memory on the Control Node, the Bluetooth connection to all mobile devices paired but not in Bluetooth range with the Control Node will be lost. To use the JHub App on these devices again, these devices will need to be repaired.

SERVICING, MAINTENANCE, AND STORAGE

SERVICING
This J35 and ControlNode contain hazardous voltages and energy hazards that may cause death or injury. Only qualified service personnel may service the J35 or ControlNode. Except where stated in the following sections, do not attempt to service the J35 or ControlNode yourself, OR dismantle, modify or repair the J35 or ControlNode yourself; this will void your warranty.
If your J35 or ControlNode requires servicing other than what is stated in this Owner’s Manual, please consult your Jayco dealer for assistance.
SERVICEABLE FUSES
The J35 air suspension and battery fuse, if required, may be replaced by the owner. To further protect from short circuits or overloading, the dealership will have fitted a 40A fuse in-line with the caravan battery and a 30A fuse at the AUX input.
If any fuse continues to fail, please contact your dealership for guidance.
MAINTENANCE
Use a dry or moist cotton cloth to lightly remove dust or dirt from the J35. Do not use alcohol, thinners, benzene, or any other chemical cleaner as these products may degrade the housing surface. Do not allow any liquids to enter the housing.
Be sure to turn off all power sources to the J35 and disconnect the battery before cleaning.
STORAGE
Once your adventure is over be sure to charge the caravan’s battery and power off all loads connected to the J35. Use the switch connected to the J35 Load Isolation input to enter Storage Mode and power off all loads.
When not in use, it is recommended that you recharge the caravan’s battery, ideally monthly, or every three to six months. Regular recharge prevents the battery from becoming a heavily discharged-a condition that can significantly shorten the battery’s lifespan.

Check the following:

1. Battery connections are tight and not loose or corroded
2. Battery polarity, red lead-positive, black lead-negative
3. The dealership fitted in-line fuse with the caravan battery is fitted and not blown. The correct value is 40A.
4. The battery fuse on the J35 is fitted and not blown. The correct value is 40A.

CARAVAN LOADS
I think one of my loads is not receiving power?
The load may be faulty, activating the protective electronic fuse and turning the load off. If this is the case, the LED Status Indicator on the J35 will flash a solid red.
Should you encounter any faulty loads, please contact your caravan dealership.
None of my loads appear to be powered but I can still use my battery monitor?
All loads will power down, but the battery monitor will still be in use if the J35 was put into Sleep Mode. The J35 will be put into Sleep Mode if:

1. The user pressed the Battery icon on their battery monitor.
   Check to see that the Battery icon on your monitor has been pressed, thus turning the power off to the caravan loads.

2. The J35 has entered Sleep Mode to conserve the remaining battery voltage and will disable power to caravan loads.
   Connect the J35 to a power source and begin battery charging.

None of my loads appear to be powered and the screen on my battery monitor has turned off?
All loads, including any battery monitor in use with the J35, will power down if the J35 was put into Storage Mode. The J35 will be put into Storage Mode if:

1. The user-activated the switch connected to the J35 Load Isolation input. This turns off power to all caravan loads and accessories connected to the J35 CAN bus such as your battery monitor.
   Check that the switch has not been activated.

2. The J35 has entered Storage Mode and to conserve the remaining battery voltage will disable power to all caravan loads and accessories connected to the J35 CAN bus. Connect the J35 to a power source and begin battery charging.

Solar Output Appears to be Lower than Expected
If the battery is close to fully charged, the J35 will periodically turn off solar to protect the batteries from overcharging. As a result, you may see less output on your solar display.
The following tips will also make sure you are getting the most out of your solar setup:

1. Make sure your solar panels are clean
   For optimal performance of your solar panels, regularly clean them (when cool) with warm, soapy water.

2. Consider the location of your caravan/RV
   A shadow (for example from trees, buildings, and even other accessories on the roof of your caravan) across any part of the solar panel can reduce the panel performance by up to 80%.

3. The time of day and time of year is important as well. In some parts of the year (especially in southern parts of Australia) the sun will never be directly overhead, so your solar output will be reduced-sometimes by up to 50%.

Table 8: Battery charging management algorithm voltages and currents
The J35 intelligently controlled charging algorithm automatically sets charging parameters so that the caravan battery will maintain the best state of health. The charging modes include:
SOFT START MODE
The charging current is maintained at 10A until the battery voltage reaches 12V or a soft start timeout (see table 7) occurs.
BOOST MODE
A feature of the J35D model only, the current is boosted to 30A to bring the battery voltage up to 14V, after which charging proceeds to Bulk Mode.
BULK MODE
The charging current is maintained at 15A until the battery reaches the Bulk voltage (see table 8), after which charging proceeds to Absorption Mode
ABSORPTION MODE
The battery is charged at Absorption voltage until the current drops below 2A or Boost-Bulk-Absorption timeout occurs.
FLOAT
The charging current is limited to 10A to keep the battery level topped up. Charging will remain in Float for 6 hours. After Float timeout, the J35 will enter back into Boost-Bulk-Absorption modes.
