1.2. Settings
1.2.1. Introduction
The first time the system is started, you need to go through
some simple steps to ensure that the system will function.
If a heating coil has been installed in the ventilation unit and
the associated settings have been made with dipswitches
in the switching space in the unit, the automatic control
system will be restarted automatically once to complete the
operation. No extra action needs to be taken. It is simply
necessary to wait until the system has restarted.
There is a quick menu to access the most commonly used
functions in the control panel, Language, Timing Program
and Setpoint Settings.
1.2.2.
Select language
To change the language on delivery:
Start page > Quick menu > Language selection >

1. Getting started
1.1. HMI
A central element in the system is the HMI (control panel), where you can adjust settings and take readings. The control panel
consists of an 8-line graphic display, indicator lamps and controls for the settings.
Here is a short introduction to the control panel showing how to enter the initial settings in the system.
1.2.3.
Login
In order to make changes to the system, it is normally necessary
to log in. There are four authority levels in the system, and three
of them are password protected. The level at which the user is
currently logged in is shown by the number of keys in the top
left hand corner of the display. The menus show more options or
fewer, depending on the level at which you are logged in.
The following actions are possible at the different levels:
Level 1: No restrictions, no password required.
• Read rights to all menus except system parameters,
configuration and detail menus.
• Read rights to alarm lists and alarm history.
Level 2: End user, password 1000.
• All rights as for level 1, plus:
• Read rights to all menus except configuration menus.
• Write rights to the most important setpoints (Setpoints/
Settings > Setpoints).
• Alarms and alarm history can be acknowledged and reset.

1.2.4.1. Set the calendar and timing program
General
This section describes functions and settings for the timing
program and calendars.
When no object with higher priority (for example Manual
control <> Auto) is activated, the system can be switched off
or the steps changed via the timing program. A maximum of
six switch-over times can be specified per week.
The calendar stop overrides the calendar exception, which in
turn overrides the normal timing program (only in operating
mode). Up to 10 periods or exception days can be specified
for each calendar.
NB! Both setpoints for fan steps and temperature setpoints
(comfort /economy) are controlled by the timing program.

1.2.4.4. Kalender (undantag och stopp)
Exception days can be defined in the calendar. These can
include specific days, periods or weekdays. Exception days
override the weekly schedule.
Calendar exceptions
Switching follows the weekly schedule and the exceptions
specified in the day schedule when a switching time is
activated in the calendar exception.
Calendar stop
The system is turned off when the calendar stop is activated.
Parameters:
Start page > Main Menu > Unit > Operating
information > Timing program > Calendar exceptions
Start page > Main Menu > Unit > Operating
information > Timing program > Calendar stops
Parameter Value Function
Current
value
– Passive
– Active
Shows whether a calendar time
is activated:
– No calendar time activated
– Calendar time activated
Val-x
– Date
– Interval
– Weekday
– Passive
Specification of exception type:
– A certain day (e.g. Friday)
– A period (e.g. holiday)
– A certain weekday
– Times are deactivated
This value must always be
placed last, after the date
-(Start)Date – Val-x = interval: Enter the start
date for the period
– (Val-x = date: Enter specific
date)
-End date Val-x = interval:
Enter the end date for the period
The end date must be later than
the start date
-Weekday Val-x = only weekdays: Enter
a weekday
EXAMPLE: Val-x = Date
Only the time for (start) is relevant.
• -(Start)Date = *,01.01.16
Result: 1 January 2016 is an exception date.
• -(Start)Date = Mo,*.*.00
Every Monday is an exception day
• -(Start)Date = *,*.Even.00
All days in even months (February, April, June, August, etc.)
are exception days.
EXAMPLE: Val-1 = Interval
The times for (Start)Date and End date are adjusted.
• -(Start)Date = *,23.06.16 / -End date = *,12.07.16.
23 June 2016 until end of 12 July 2016 are exception days
(for example holidays).
• -(Start)Date = *,23.12.16 / -End date = *,31.12.16
23–31 December are exception days every year. Time End
date = *,01.01.16 will not work because 1 January comes
before 23 December.
• -(Start)Date = *,23.12.16 / -End date = *,01.01.17.
23 December 2016 up to and including 1 January 2017 are
exception days.
• -(Start)Date = *,*.*.17 / -End date = *,*.*.17
Warning! This means that the exception is always active!
The system is constantly in exception mode or turned off.
EXAMPLE: Val-1 = Weekday
Val-1 = Weekday
The times for weekdays are adjusted.
• Weekday = *,Fr,*
Every Friday is an exception day.
• Weekday = *,Fr,Even
Every Friday in even months (February, April, June, August,
etc.) is an exception day.
• Weekday = *,*,*
Warning! This means that the exception is always active!
The system is constantly in exception mode or turned off.
