EXact control system

Behind every operation, the advanced EXact control ensures the air

handling unit operates as effectively and economically as possible.

The control can easily be adjusted to the daily rhythm of the

location, whether it is a school, of ce or residence.

The essential EXact parameters are:

• Simple operation

• Three user modes, two which require access codes

(technician and specialist)

• Several indoor air quality levels with options such as

on-demand ventilation via the built-in weekly clock

• Built-in web server allows monitoring and control over the

internet (TCP/IP)

• Can connect to a DDC unit via Modbus RTU as standard

and LON options

• See several more selected functions in the function overview

HMI control panel

The control panel is designed so that it can be operated in

two modes, locked or opened. If set in locked mode, the

control panel can only be used for normal, daily use, and

the user cannot access advanced menus or parameters.

In opened mode, the technician or specialist has access to

extra buttons and to more more advanced menus and

functions. The control panel requires a code to be operated

in open mode.

Temperature level/

ventilation level

Temperature and

ventilation levels can easily

and quickly be changed

temporarily. Set points are

shown together with visual

symbols in the display.

Alarm/warning

The EXact control system will

generate a warning symbol if

it detects operational

disturbances. The display will

show an alarm bell if more

serious disturbances have

been detected.

External stop

If the ventilation system

has been stopped by an

external stop signal, this

symbol will appear in the

display.

De-icing

If the built-in de-icing

function is in operation,

this symbol will appear in

the display.

User menu

The user menu is for daily

operations. It shows visual

symbols to indicate the

unit’s status and provide

information. The interface

allows the user to

temporarily change the

temperature and

ventilation level.

Support texts

The very useful support

texts displayed in the

yellow area minimise the

need for manuals and

instructions. Support

texts are available in

both technician and

specialist modes.
