have to be placed in the ducts.

See 2.10 Installing sensors for control (accessory)

Manual version 4.1 (26-07-2018)

When opting for the duct cross-section, take into account:

n If the duct cross-section is too small, this may lead

to reduced capacity and/or noise nuisance.

n When adapting to different duct diameters, use

sufficient length in order to prevent turbulence.

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

Connection X3 1 is suitable for input signals that are externally powered.

Connection X1 2 is suitable for supplying the sensor that is to be connected with a 230V power supply from the unit. When using this, link connection X1 to X3 with a bridge.

c The input is designed for controls with potential-free

contacts and must not be loaded.

n When using the input, indicate what response must

be given to an input signal. (Via the b-touch control panel: menu > Configuration > 60. Function of inputs or via the building management system: register address 337 Alarm functions)

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.

This function will be active if the pressure difference across the plate heat exchanger becomes too great.

n The pressure difference must be measured in fan

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

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

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
