2.7 Connecting the unit to Modbus

2.7.1 Communication parameters

Standard values of the communication parameters for Mod­Bus are:
COMMUNICATION PARAMETER VALUE
Baud rate 9600
DATA 8
Parity none
Stop bits 1
The turnaround time between the unit and Modbus is 4.2 msec.
The default value for the Modbus node address is 1.
n You can modify the parameters via b-touch
menu > Maintenance > Modbus settings or
via Modbus register addresses 460-464.

2.7.2 Wiring

A twisted-pair cable must be used for connection to the Mod­bus system. The cable must also have a third core for the GND (grounding). Normally, a four-pole, twisted-pair cable is used; one pair is used for communication and one core from the other pair is used as the GND.
Modbus A = -
Modbus B = +
GND = ground
Manual version 4.1 (26-07-2018)
n If there is no communication, this may be caused by
incorrectly connected wiring. Swap the A- and B+ wires.

2.7.3 Connecting the unit to Modbus

1. Lay a cable between the Modbus system and the unit.
2. Connect the cable to the electronics module 1, in accord- ance with the wiring diagram.
n For a more reliable signal, it is possible to connect a
120 Ohm resistor. For this purpose, place a bridge between positions 1 and B of terminal 52X3 on the control circuit board in the unit.
n The b-touch control panel is no longer necessary for
the operation. After going through the installation guide, it can be removed. However, make sure to keep it to be able to adjust the settings in a later stage.

2.8 Installing the b-touch control panel (accessory)

2.8.1 Special points regarding the control panel

Positioning

• You can attach the control panel to the electronics mod­ule, to the wall or to a standard junction box.

Cabling

n Take the following into account, otherwise errors
may occur:
- The length of the control cable between the contro p
anel and the unit connected may not exceed 50 m.
- Keep control cables away from electromagnetic fi
d interference sources such as high-voltage ca
an an
d fluorescent light starters.
- Lay control cables out straight or roll them in a bifi­lar coil by folding cables in half before rolling them. As a result, the magnetic fields will cancel each othe

In emergencies, the unit can emit an alarm signal or even actively deal with the problem by functioning in a special mode. (See menu > Configuration > 60. Function of inputs)
This function can be activated by the building management sys­tem (register address 435) or by an external sensor.
If an external sensor is used:
1. Place a smoke detector or fire alarm (not supplied) at
su
itable location.
2. Without using the power supply (230V) from the unit:
- Connect the sensor to X3 1 in the electronics mod-
ule in accordance with the wiring diagram
3. Using the power supply (230V) from the unit:
- Connect the sensor to X1 2 in the electronics mod-
ule in accordance with the wiring diagram
- Place a bridge between X1 and X3

2.13.6 Setting the pressure switch

The unit is fitted with freezing protection for the plate heat exchangers. If ice formation is identified, the unit will defrost the exchangers by blowing warm indoor air over the exchang­ers. The airflow from outside in will be turned off.

speed 3 (high).
At outside temperatures that form the risk of freez­ing, the unit will carry out a check by measuring the pressure difference at fan speed 3.

Adjust pressure switch

Adjust the pressure switch 7 to fan speed 3 (high):
1. Use the flow rate that is used for fan speed 3 of the extract fan (see 2.13.5 Calibrate air volume).
2. Determine the corresponding pressure difference for pr

installation and specific information per group and per unit connected.
Current errors Gives an overview of current errors. The error messages can
also be deleted here.
Error history Gives an overview of the errors which have occurred.
Capacity test Use this function to test the capacity of the unit and your
heating installation.
The unit will run for 120 minutes at the highest fan speed and with the highest heating capacity. You can check the discharge temperature and the heating capacity. The discharge tempera­ture is limited to 50°C.
For units with water heating:
If the heating capacity is too low, check the supply and return water temperatures and the water flow.
Valve check Use this function to test the operation of the water valve:
1. Set the opening percentage of the valve to 0%;
2. Press start. The fans will start rotating at the highest speed;
3. Check whether the discharged air is cold;
n It may take some time before the valve reaches the
adjusted opening percentage.

3.8 USB

The control panel is equipped with a USB port to which only a USB flash drive can be connected. This is used for:
• updating the software
• importing and exporting settings
• exporting usage data
This menu is automatically activated when a USB flash drive is connected. The menu is closed again when the USB flash drive is removed.
c Do not remove the USB flash drive during the
updating or during the importing or exporting of data. This can take several minutes.
w Connection of other electronic devices to the
USB port can cause serious damage to the control panel or to other electronic components.
Software update Biddle is working continuously on improving its products and
recommends that you update the software of the control panel when updates become available. Consult www.bid­dle.info/software to see if updates are available.

4. . Operation via Modbus
The unit can be operated via the b-touch control panel and via Modbus. This chapter describes the operation via Modbus.
n Some settings and functions can only be used via the
b-touch control panel or, conversely, only via Modbus.

4.1 Frequently used register addresses

This paragraph describes frequently-used functions and their corresponding register addresses.
c Do not adjust other register addresses without
consulting Biddle.
n It may occur that the system applied uses a value of
1 higher than the register addresses given here. In that case, use 101 for register address 100, for example.
n For functions that are also in the b-touch panel, the
corresponding menu parameter is shown between brackets after the register address.
Menu parameters 0 - 1 are functions in the home screen.
en-52
n Settings in the b-touch control panel can cause
Modbus settings to be ignored. In register addresses 410 to 419 inclusive, it can be specified whether settings may be altered via the b-touch.
Register addresses 410 - 419 are related to 400 ­409 and 420 - 429 respectively.

6.2 Replacing the filter

The unit is fitted with two filters:
•Fresh air filter: F7 1.
• Extract air filter: M5 2.
The filters must be replaced regularly. A dirty filter can cause inefficient operation and a high noise level.
Remove the filter:
w Set the isolation switch to 0.
1. Open the inspection hatch for the relevant filter.
2. Pull the clamps downward 3.
3. Remove the filter 4.
4. Replace the filter. New filters are available from Biddle.

6.3 Cleaning the unit

You can clean the interior and exterior of the unit with a damp cloth and a domestic cleaning agent. Do not use any sol­vents.

6.4 Scheduled maintenance

It is recommended to have the following inspection and main­tenance activities performed annually by an installer or other technical expert.
• Check the casing, the suspension or mounting structure, and the securing of the unit.
• Check whether the filters are clean enough and undam­aged. Replace the filters if necessary.
• Check that the heat exchanger or the electrical heatin

before replacing the fuses.

7.5 Setting the unit code

The unit code must be set after replacement of the control circuit board in the unit. The unit code depends on the unit type and is indicated on the type plate.
To set the unit code, there are two methods:
• directly via the control panel if a single unit is connected;
• via the control circuit board and the control panel if more than one unit is connected.
w Entering an incorrect code will result in poor
performance of the unit.

7.5.1 Setting the unit code via the control panel

work if just a single unit is connected to the control panel. If necessary, connect the control panel separately to the unit in question.
