INTRODUCTION

OJ-AIR2-HMI-35T is a touchscreen panel with user-friendly graphical user interface specially deve­loped for controlling ventilation systems. The panel communicates with the OJ-Air2 system via a
Modbus interface, ensuring easy installation.

PRODUCT PROGRAMME
Product Type

OJ-AIR2-HMI-35T 3.5” touchscreen panel

OPERATION

This quick start guide only describes basic settings. If the screen saver
is active, simply touch the screen once to open the home screen. This
screen provides access to elementary functions such as fan speed,
temperature and setup. The time and day of the week are shown in
the top line of the screen.
Below these, an alarm bell is visible if an alarm has been activated. The
house in the middle section of the screen provides access to a simple
overview of temperatures, air volumes and lter pressures. The tem­perature shown to the right of the house is the temperature setpoint.
The icons shown in the lower part of the screen can be changed and
may therefore differ from those shown in these instructions.

FAN SPEED

To set fan speed, press the fan in the lower part of the home screen.
You can choose between ve predened fan speeds. Off, Auto, Low,
High and Service Stop. If you choose Auto, OJ-AIR2-HMI-35T will fol­low a predened program. If you choose Low, the predened program
is overridden and the fan operates at low speed. If you choose High,
the predened program is overridden and the fan operates at high
speed. If you choose Off, the fan comes to a complete standstill until
fan speed is again changed. If you choose Service Stop, the system
shuts down and can only be restarted locally from the control panel.

TEMPERATURE

To change the temperature setpoint for the selected control mode,
press the temperature on the panel's home screen. Change the tem­perature using the arrows and conrm with the green button.

SETTINGS

OJ-AIR2-HMI-35T is used together with an OJ-Air2 Master, and all communication is via the master.
Some settings can be made via the menu icon in the upper right corner of the home screen.
Begin by pressing the menu icon in the upper right corner of the
home screen. The following screen is then displayed:

Home

Press this icon to return to the home screen.

Communication

Weekly program

Here you can enter times and modes for the built-in 7-day clock.

Alarms

Here you can view active alarms and an alarm log. In case of an alarm,

this screen can also be accessed via the bell icon on the home screen.

Extended operation

If a different pattern of operation is required for a short period of
time, the weekly program can be overridden. The override period can
last up to a week at most. Once the period has elapsed, the system
returns to standard clockcontrolled operation.

Unit components

Here you can make general settings for the various components that

are installed.

Software update

Here you can check if an SD card inserted into the OJ-Air2 contains
a new software version.

Settings

The following can be set/viewed:

• Language

• Time & date

• Locking of fan speed during adjustment.

• Setting of fan speed in case of re/smoke extraction

• Setting up the lower part of the screen

• Software version

Language

Here you can choose the language to be used on the screen.

Time & date

Here you can set the time and date for the system.

Adjustment

Here you can lock fan speed during system adjustment. Once the
required air volume has been reached, the fan is locked at its current
speed. This gives the installer the opportunity to adjust the system,
ensuring the right amount of air in the individual rooms without in­terference from ventilation system regulation.

INSTALLATION

OJ-AIR2-HMI-35T can be installed in two ways: either in a wall box/
panel front or directly on a at surface.

Installation on at surface

The back cover of the HMI is equipped with a keyhole-shaped opening which can be used to hang
the unit on a at surface (see Fig. 1). Use a screw that is max. 3.5 mm in diameter with a head no

larger than 9 mm.

Installation in wall box/panel front

If OJ-AIR2-HMI-35T is to be installed in a wall box or panel front, the back cover must be removed.
Firstly, the front cover must be detached by gently releasing the catch on the bottom of the unit
with a at screwdriver and then tipping the cover outwards (see Fig. 2).
Once the front cover has been detached, the two screws holding the back cover in place can be
removed (see g. 3). The back cover can now be detached and the front cover retted. The baseplate
is equipped with several screw holes. The dimensioned drawing (see g. 4) can be used as a drilling
template. The baseplate should be secured with at least two screws tightened to a torque of max.

0.8 Nm. Installation depth is 20 mm.

MODBUS CONNECTION

OJ-AIR2-HMI-35T is connected to the OJ-Air2 Master by means of a Modbus cable. The Modbus ca­ble can be connected to the OJAIR2- HMI-35T by means of the RJ12 6P4C port or four single-wire
screw terminals. Whether the RJ12 6P4C port or screw terminals are used does not inuence the
available functions or operation.

Modbus RJ12 6P4C

Connect the Modbus cable to the Modbus port for a hand terminal on the OJ-Air2 Master and to
the RJ12 6P4C port on the OJ-AIR2- HMI-35T (see g. 5).

Modbus screw terminals

Connect the Modbus cable to the Modbus port for a hand terminal on the OJ-Air2 Master and to
the corresponding screw terminals on the OJ-AIR2-HMI-35T (see g. 6).

BEDIENUNG

Diese Kurzanleitung enthält nur die Grundeinstellungen. Bei aktivem
Bildschirmschoner für Zugriff auf die Startansicht einfach auf den
Schirm tippen. Dieser Bildschirm ermöglicht Zugriff
auf grundlegende Funktionen wie Lüfterdrehzahl, Temperatur und

am Bildschirm angezeigt. Wurde ein Alarm aktiviert, erscheint unmit­telbar darunter eine Alarmglocke. Das Haus-Symbol im mittleren Teil
ermöglicht Zugriff auf ein Übersichtsbild mit Temperatur-, Luftmen­gen- und Filterdruckangaben. Rechts vom Symbol wird der Tempera­tursollwert angezeigt. Die Symbole im unteren Teil der Startansicht
können sich ändern und daher von den Abbildungen

abweichen.

LÜFTERDREHZAHL

Die Lüfterdrehzahl wird durch Antippen des Lüftersymbols im unte­ren Teil der Startansicht eingestellt. Zur Wahl stehen 5 voreingestellte
Lüfterdrehzahlen: Aus, Aut., Niedrig, Hoch und Servicestopp. In der
Einstellung Aut. folgt OJ-AIR2-HMI-35T einem vordenierten Pro­gramm. In der Einstellung Niedrig wird das vordenierte Programm
übersteuert, und der Lüfter mit niedriger Drehzahl betrieben. In der
Einstellung Hoch wird das vordenierte Programm übersteuert, und
der Lüfter mit hoher Drehzahl betrieben. In der Einstellung Aus steht
der Lüfter still, bis die Einstellung wieder geändert wird. In der Einstel­lung Servicestopp stoppt die Anlage und kann nur lokal vom Bedien­feld gestartet werden.
