4 CONTROL PANEL, OPERATIONS, COMMISSIONING
4.1 GENERAL
HMI
This section provides an introduction to the touchscreen LCD
control panel, also known as the ‘Human Machine Interface’, or
simply, HMI.
The HMI serves two main purposes: To provide information about
the current operational state of the unit. To allow the unit to be
setup and configured.
TOUCH SCREEN TIPS
To select an item, touch the center of the icon or option. Do not
press too hard, the touch screen is sensitive enough to pick up
light, firm touches. Use the tip of your finger or the back of a
pencil to touch the required option. Be careful not to touch any
other options.
CLEANING THE SCREEN
Disconnect the power cord. Gently wipe the screen with a soft,
dry non-abrasive cloth. If the marks remain, moisten the cloth
slightly with a detergent that is designed for LCD or mobile
screens and wipe the screen gently from top to bottom. Never
use other detergents, as these may contain ammonia or other
additives.
IMPORTANT:
• Never spray, or pour liquids directly on to the screen.
• Do not clean the screen while the system is on.
CONVENTIONS USED WITHIN THIS MANUAL
The following buttons and symbols are universal and available on
many menu pages.
Home key, to return to the Home Screen.
Back button, to cancel and return to the previous
page.
Confirm button to confirm and proceed.
Changing a value:
Option 1: Press the arrow keys to increase or
decrease the value.
Option 2: Press the displayed number to
numerically adjust the value.
USING THE UNIT
POWERING ON
Each time power is applied, the unit will run through a series of
internal system tests which take approximately 20 seconds to
complete.
Once the internal system tests have been completed, the HMI will
always display the Home screen. The unit will be in Manual Mode
the first time that power is applied.
HOME SCREEN
From the Home screen it is possible to determine how the unit is
operating as well as navigating to further screens to configure the
unit to suit the demands of the end system.
From the Home Screen, it is possible to:
Navigate to further configuration screens to setup system para-
meters.
• Manually adjust the fan speed.
• Determine the operating status of the product.
• Interrogate and acknowledge system alarms.
Use the number buttons to enter
a value.
Confirm with or cancel with .
Values that can only be read, but not written,
are displayed without a surrounding window.
Values that can be both read and written,
are displayed with a surrounding window.
Some submenus has several
pages. Touch the upper or the
lower part of the scroll list to
navigate between pages.

OPERATING MODES
The operating status icon present on the Home Screen dis-
plays the current operating mode. To change the operating
mode, press the large fan icon located on the Home Screen.
The unit has three operating modes selectable through the
Operating Modes screen:
Stop Mode: In this mode, the unit will stop both the
supply and the extract fans.
Manual Mode: In this mode, the unit can be manually
adjusted on the Home Screen to run at three different
speeds.
Automatic Mode: In this mode, the unit will be automa-
tically controlled using internal schedules and timers,
CO

demand control, PIR sensors, etc.
ALARM SCREEN
The alarm icon on the Home Screen indicates the status of any
system alarms:
Alarm type B are deemed non-critical
and do not stop the unit ventilation.
Alarm type A are deemed critical and will
cause the unit to stop ventilating.
Press the icon to enter the Alarm Screen.
USER SETTINGS
TEMPERATURE STATUS
The temperature set point is used to determine when
the post-heater (if fitted) starts to warm the supply air
entering the property. The temperature set point can be
adjusted to any temperature between 15° C and 35° C,
factory setting is 19° C.
Temperatures and output signals are read only values.

Numerous system parameters can be adjusted through the
Settings Screen; however, only those that are relevant and app-
ropriate to the scope of the HMI User Manual will be described. It
is strongly recommended to avoid the adjustment of any system
parameters not outline within this section.
Access to the Settings Screen is passcode protected to prevent
system critical parameters from being accidentally adjusted to
values that could compromise the correct operation of the unit.
Therefore, extreme caution should be observed when adjusting
