2.2. Settings
2.2.1.
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.
2.2.2.
To change the language on delivery:
Start page > Quick menu > Language selection > HMI Language > English
Changes the menu language to English.

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 day. 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.

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!

4. Backup and program updates
When the system has been fully configured and the parameters have been set, it can be backed up to an SD memory card or reset using the data on the memory card. Two different sets of parameters for a configured system can be backed up or reset. For example, you can back up the standard settings (Save factory settings) and adjusted settings (Save startup settings).
The options below can be selected only with the relevant authority level. This is done using menu option:
Start page > Main menu > System overview > Save/Reset
4.2. Load a configuration
Procedure:
1. Insert the memory card into the regulator.
2. Load the values from the memory card.
Start page > Main menu > System overview > Save/Reset > Load param. <-S = Execute
3. Wait until:
Start page > Main menu > System overview > Save/Reset > Load param. done = Yes
4. Restart the process unit:
The regulator has a card slot for an SD memory card with max 2 GB capacity.
4.1. Save a configuration
After initiation and adjustment, the parameters and configurations can be saved to the SD card. For example, you can load these values on another process unit with the same basic configuration (operating system, application, control panel, HMI4Web and language/communication). Authority level 4 is required.
Location of SD memory card
Start page > Main menu > System overview > Save/Reset > Restart = Execute
RESTART
Standard settings (Factory settings) and adjusted settings (Startup settings) are handled in the same way.
4.3. Loan an application or software
Preconditions:
• The (uncompressed) files must be in the root folder of
the SD memory card.
• The files must have the names shown in the screen below.
Files on SD card
Procedure
1. Insert a blank SD memory card into the regulator.
2. Backup the values to the memory card.
Start page > Main menu > System overview > Save/Reset > Save param.->SD = Execute
3. Wait until:
Start page > Main menu > System overview > Save/Reset > Save param. done = Yes
Standard settings (Factory settings) and adjusted settings (Startup settings) are handled in the same way.
Procedure
1. Insert the memory card into the regulator.
2. Switch off the regulator.
3. Press the button in the hole next to the regulator's
status screen with a thin object so that a clicking sound is heard, and keep the button pressed down.
4. Switch on the regulator.
5. Wait until the LED flashes red and green.
6. Release the button.
7. Wait until orange LED lights up.
8. Switch off the regulator.
9. Switch on the regulator.

4.4. Error diagnosis - Snapshot
For troubleshooting, the status of the ventilation unit just before the alarm was triggered can be studied afterwards by means of export to an SD card. Authority level 4 is required.
Procedure:
1. Insert a blank SD memory card into the regulator.
2. Backup the error diagnosis to the memory card.
5. General functions
Operating modes - Change
The system can be put in different operating modes.
Start page > Main menu > Unit > Operating functions > Continuous operation
Start page > Main menu > System overview > Save/Reset > Save snapshot = Execute
3. Wait until:
Start page > Main menu > System overview > Save/Reset > Save snapshot = Yes
A file has now been generated on the SD card that can be read from a PC.

6. Configuration
On delivery, the ventilation unit is configured and ready. Normally, therefore, no adjustments need to be made to the configuration.
However, the addition of accessories and other equipment may require a change to the configuration. Where necessary, there is a more detailed description in this manual or with the accessory. This section is, therefore, intended more as general information.
The configuration includes the following four steps:
• Activate and choose type of after heater on circuit board A3
• Configuration 1
• Configuration 2
• Configuration with inputs and outputs
6.1. Configuration 1
If adjustments are needed, ‘Configuration 1’ is the first step in the configuration.
• Configuration is done sequentially, which means that it is not possible to skip any options.
• Configuration 1 must have been completed and the process unit have been restarted before you continue with Configuration 2.
Start: If necessary: Enter the password for level 3:
Start page > Log in
Then:
Start page > Main menu > Configuration > Configuration 1
After making a change in a configuration menu, a restart is required.
Start page > Main menu > Configuration > Configuration 1 > Restart > Execute
NB! The ventilation unit is supplied fully configured

Setp.FF step 3 Extract air fan setpoint speed 3
If SF slave or EF slave is selected for the fan regulation type, an offset must be set against which the fan selected is regulated. The supply air/extract air fan is pressure-regulated. The supply air/extract air flow is calculated and regulated against the slave offset. See example.
Start page > Main menu > Unit > Fan control > Slave offset
Explanation: The offset indicates the difference between the master fan and the slave fan.
> EXAMPLE OF OFFSET
Example 1: If the offset is 0 l/s, the slave fan
operates with the same flow as the master fan.
Example 2: If the offset is -100 l/s, the slave fan
operates with 100 l/s lower flow than the master fan.
Example 3: If the offset is 100 l/s, the slave fan
operates with 100 l/s higher flow than the master fan.
10.3. External fan setpoint
The fans can be controlled directly via an analogue 0-10 V input on the automatic control. Min. and max. speeds/flows are defined, which correspond to 0 V and 10 V on the input.

The function works in such a way that when the heat pump is defrosting (signal in on block P12-35), the control system is automatically started up from the regulator to the heat pump until defrosting plus an extra period has elapsed, when it will start to regulate again. If internal electrical coils have been installed and configured, these will attempt to maintain the supply air temperature during the defrosting period. This is to prevent the heating sequence switching over when the heat pump has finished defrosting.
To adjust the function’s locking time:
Start page > Main menu > Unit > Temperature regulation > Additional heating > Heat pump defrost. Lock electrics
The standard setting is 60 seconds.
