2. Settings

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.

Then go through the following steps:

2.2. Select language

Five languages are supported in the system:

• English

• Norwegian

• Swedish

• Danish

• Finnish

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.

English is selected as the factory setting. In order to change the

language, authority level 2 at least is required (password 1000).

The menu option for making the change is:

2.3. Set Time/Date

To change the time and date, go to the menu option:

2.4. 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.

3. Adjust setpoints

3.1. Temperatures/Air ﬂow

The menu option for adjusting temperature setpoints and

air ﬂow is:

Temperature setpoints can be changed on lines three and

four. Air ﬂow values can be changed on lines ﬁve to ten.

The default conﬁguration in the unit is for constant air ﬂow

regulation.

4. Select method of regulation

4.1. Extract air regulation

Limits the supply air temperature in connection with pure

room or extract air regulation so that sudden ﬂuctuations

are avoided when temperatures are too high or too low.

6. Set the calendar and timing

program

6.1. General

This section describes functions and settings for the timing

program and calendars.

When no object with higher priority (for example Manual

operation <> Auto) is activated, the system can be

disconnected or the stages altered from 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.

6.2. Week schedule

Parameter Value Function

Current

value

--- Switching according to

schedule.

Monday Shows current command when

the current day is Monday. The

latest time that can be entered

Sunday Same function as for Monday.

Exception Shows current command when

the current day is an exception

day. Go to the day switching

schedule for exception days.

Period:

Start

Period:Start

(Only Authority level 3.)

Start date for week schedule.

*,* *.00 means that the week

schedule is always activated.

---> Activate week schedule.

Period: End

Period:Start

(Only Authority level 3.)

Start date and start time for

inactivating week schedule.

6.3. Day schedule

Parameter Value Function

schedule when the current

weekday is the same as the

switching day.

Day

schedule

– Passive

– Active

Status for current week or

exception day:

– Current weekday (system

day) is not the same as the

switching day.

– Current weekday (system

day) is the same as the

switching day.

Time-1 Special case: This time must

not be changed, and must

always be 00:00.

Value-1 Switching command for Time-1.

Time-2 Switching time 2.

*: * ---> Time inactivated.

Value-2

...

Value-6

Analogue value 1.

Time-3 ...

Time-6

6.4. Calendar (exceptions and stop)

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 stops

The system is turned off when the calendar stop is activated.

Parameter

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 inactivated.

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 = *,01.01.09

Result: 1 January 2009 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 = *,23.06.09 / -End date = *,12.07.09.

23 June 2009 until end of 12 July 2009 are exception days

(for example holidays).

• -(Start)Date = *,23.12.00 / -End date = *,31.12.00

23–31 December are exception days every year. Time End

date = *,01.01.00 will not work, because 1 January comes

before 23 December.

• -(Start)Date = *,23.12.09 / -End date = *,01.01.10.

23 December 2009 up to and including 1 January 2010 are

exception days.

• -(Start)Date = *,*.*.00 / -End date = *,*.*.00

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.
