WISE Care Package 1
In WISE Care Package 1 the focus is on flexibility, time- and cost savings. This is achieved through the innovative functions
available in WISE Care Package 1.
WISE Care Package 1 is for the entire WISE-system, i.e. room-, zone- and system levels, which means the update is an
comprehensive solution to the WISE-system.
The system is self-commissioning which results in time- and cost savings. WISE Care Package 1 consists of following
functions:

2-Steps optimisation
Zone- and room optimisation
The 2-steps optimisation is a further development of the current optimisation performed by the Super WISE. All zone
dampers continuously monitor the damper position of the products that are on the level below the zone dampers, and
are connected via Modbus. It is always the room damper with the greatest degree of opening which controls the zone
damper for optimisation.
During normal operation, the most open room dampers are normally 70-90% open. If the most open room damper is
open more than 90% it is not enough airflow in the zone. The zone damper will in this case open until the most open
room damper is open less than 90%. If the most open room damper is open less than 70%, the airflow in the zone is
too high. The zone damper will in that case close until the most open room damper is open more than 70%.
Figure 1. If a room damper is outside of the limit 70-90% open, the zone damper adjusts by opening or closing.

AHU and zone optimisation
Super WISE continuously monitors the position of the zone dampers, according to the same principle as previously
described for room dampers. The AHU’s pressure set point is increased/decreased depending on the need in the zones.
The router simulates a zone damper and always displays the most open room product for both supply air and extract
air, which is connected via Modbus to the router. If only a supply air or an extract air is connected, the router will only
show this.
Figure 2. If a zone damper is out of the limit 70-90% open, the AHU will increase/decrease the unit’s set point until the zone
damper is within the limits.
The system is optimized continuously at all levels to keep the pressure drop as low as possible during all circumstances.
Since the system is self-commissioning, air adjustments are no longer necessary. This saves both work time and money.

Summary of airflow
Summary of airflow is a function which allows summation of air flows from room products. The summed air flows are
sent as a set point to a central extract air, which is either a zone damper or an extract air room product.

Figure 4. Illustration of airflow summation.
Example
Example 1
Select the supply air room products to be summarized. This air flow sum is sent as a set point to a zone damper, i.e.
CONTROL Zone FE, which is a central extract air.
One or several extract air room products can then be subtracted from the air flow sum.
Example 2
In this example, a room-product is used as a central extract air. A number of supply air products are summed, the total
air flow is sent as a set point to the extract air product. One or several extract air diffusers can be subtracted from the
air flow summation.
NOTE!
• All room products which will be summed must be connected via Modbus RTU to the same zone product.
• If a zone product has an airflow summation as a set point, the summed room products must be connected via Modbus RTU to the zone product.
• The extract room air must be connected via Modbus RTU to the same zone damper as the supply air room products.

Setting the airflow summing
All settings for the summation function is easily done via the Super WISE webpage. Below is an example of this, where
one summation group has been created, which belongs to the zone control with Modbus ID 1.
In ”group number 1” three room products have been selected. MB-ID: 8, 12 and 16, to be summed to MB ID 250 with
an offset selected to -150 l/s. Which means 150 l/s less air will be extracted than the summed airflow. This function can
be applied when a mechanical adjusted constant flow damper is used, i.e. a toilet-group.

Other functions in WISE Care Package 1
►►
Global commissioning
The function global commissioning enables to put the entire system, or a single zone, in any commissioning
mode. This is performed by single button push in Super WISE. The user chooses which commissioning mode the
room products should be in, and chooses whether this applies to all zones or only a specified zone . A counter
will start counting from 0-100%. When the counter has reached 100%, all room products are in the chosen
commissioning mode.
This applies both for the commissioning of airflows and for the commissioning of valve actuators for water circuits. Valve actuators for water circuits can be forced to fully open. This can be done for valve actuators for cooling
or for valve actuators for heating, both cannot be forced to fully open simultaneously.
When the system or a zone is set in a specific commissioning mode the room products remain in this position
until one chooses to once again put them in normal mode. This is done by the same simple procedure that were
used to put them in commissioning mode.
Example of when this feature is useful and saves work time:
All room products are delivered adjusted to commissioning mode with maximum flow from the factory, this is
to facilitate the commissioning. All room products will continue to be delivered in this mode, even though the
2- steps optimisation is selected. Since no commissioning is required when the 2- steps optimisation is used, it is
still desirable to have the products set to maximum flow. When the entire system is powered on and the 2- steps
optimisation is in use, the max flow setting is used as a safety control to make sure everything is working as it is
intended to. When the system is checked and the user is satisfied with the functionality, the entire system can be
put in normal operation by the simple method described above.
By using the global commissioning function the user saves a lot of time compared to before. Before, it was necessary to either visit each room to manually set the products to normal operation using the controller TUNE Adapt,
or manually go into each room in Super WISE and set the products to maximum flow through the web page.

Light Control
With WISE Care Package 1, it is possible to use an momentary light switch together with the integrated
occupancy sensor to control the lighting in rooms. By connecting an impulse light switch to the airborne ADAPT
products in the WISE system, additional electrical energy is saved when the user must make an active choice to
turn on the lights in a room.
When the user enters a room and wishes to turn on the light, a light switch is used and a signal goes to the
ADAPT product, which turns on the light via ADAPT Relay, ADAPT Triac or other suitable third party relay. If the
user wishes to turn the light off, the light switch is used and the ADAPT product turns off the light.
If the user leaves the room, without turning off the light, a timer starts counting down from a pre-set value.
When the occupancy sensor does not detect any presence, within the pre-set value, the ADAPT product will
automatically turn off the light in the room for maximum energy savings. If the sensor detects presence within
one minute after the light was turned off, the lights will automatically be switched on. If no presence is detected
within one minute, using the light switch is required to turn on the lights.
This function removes energy waste by removing the chances of accidental switching on the light in a room.
Which could be caused by, for example, someone passing by in the hallway or outside the window.
To facilitate the connection and to ensure the lighting function, a special CONNECT Adapt has been developed, it
should always be used with the new lighting feature. The lightning is connected to the CONNECT Adapt as usual
on a screw terminal. If further simplified wiring is desired there is a wiring box with quick connectors and built-in
relay available as an option.
To turn on the light, use
the light switch!
If the ADAPT product
does not detect any
presence during the predefined time the light is
turned off.
If the ADAPT product
detects presence within
one minute, after the light
is turned off, the light is
automatically turned on.

Another light feature has been added which enables great flexibility. In addition to creating air flow groups at
room level, it is also possible to create light groups. If it is desired that the lighting in two or more rooms (maximum 100 rooms) should be switched on, or off, at the same time, the user creates a group of rooms which
should have common lights. When a user switches on the light in one room, the lights will be switched on in all
the rooms included in the group. As long as any of the occupancy sensors detect presence in one of the rooms,
the lights will be on in every room (in the group). When none of the occupancy sensors have detected any presence, during the predefined time, the lights will be turned off in all the rooms.
This function is very convenient when, for example, two separate offices with an ADAPT product in each room,
is rebuilt to one large room. There is no need to re-wire the wires for light control, neither from light switches or
fixtures.
The lighting group functionality is only intended for use with the new lighting control function described on
the previous page.
When creating occupancy groups, only the internal occupancy in the products’ controllers is set and is therefore only intended for ventilation control.

Normally open valve actuators
All room products in the WISE system, with WISE Care Package 1, supports normally open valve actuators. Previously, only the airborne ADAPT products handled normally open valve actuators and remaining products only
supported normally closed valve actuators.
Normally closed valve actuator means that when the actuator is not powered, the actuator is closed. This solution
is ideal for when you want to control a flow of water that is not critical to be throttled in case of power blackout
in the room or building.
Normally open valve actuator means that when the actuator is not powered, the actuator is fully open. This solution is best when you want to control a flow of water which is critical not to be throttled by a power failure in the
room or building. For example, the hot water in colder climates. This solution will consume more electrical energy
when the valve actuator is powered when it is not open, which is generally most of the time.
►►
Cold draft
All room products in the WISE system, with WISE Care Package 1, has the function cold draft protection for
radiators mounted below windows. Previously, this function was only available in the ADAPT products, but is now
also available for CONTROL Room, CONDUCTOR W1-W4 and ADAPT Parasol.
Until the cooling condition exceeds the set value (default 50%), the product will keep the valve actuators for heat
partially open (default 20%). Cold draft is then avoided close to windows when the temperature outside is cooler
than the temperature inside. The radiator, mounted below the window, is letting a bit of heat to rise. This prevents cooling of the air closest to the window; this air is then prevented of falling down in the zone and creating
discomfort.
Figure 9. Cold draft protection.
►►
Forced closing of zone dampers
During renovation of a building, in many cases it may be desirable to turn off the ventilation on the part being
rebuilt. With WISE Care Package 1 it is possible to force one or more zone dampers to be fully closed to not vent
the part of the building being renovated. The zone dampers will be fully closed with damper leakage class 4 for
circular dampers, or damper leakage class 3 for rectangular dampers, until you choose to enable normal operation again. Forced closure and reset to normal operation is easily done by pushing a button in Super WISE. It
is also possible to force a zone damper to fully open, through the same way just described. Zone damper shall
always be set to ”Auto” mode, if you go in between these settings.

Alarm handling
WISE Care Package 1 consists of several new alarm functions.
Operating status of the AHU
Super WISE constantly checks the operating status of the AHU. When the unit is idle or is turned off, for
example overnight, all the alarms in the WISE system related to no air being produced will be blocked in the
Super WISE, until the unit is re-activated and starts producing air.
The following alarms are blocked when the AHU is turned off :
Airborne ADAPT products
• Alarm no. 8 - Room temperature deviation too high
• Alarm no. 9 - CO2 level too high
• Alarm no. 10 - Comfort alarm: RH deviation
• Alarm no. 11 – AHU VOC-level greater than VOC-level
• Alarm no. 12 - Moisture addition is too high
CONTROL and CONDUCTOR
• Alarm no. 11 - PI controller overload
• Alarm no. 12 - Set point not reached
• Alarm no. 13 - Incorrect supply air temperature
• Alert No 41 - No supply pressure from AHU
• Alarm no. 42 - Nothing exhaust pressure from AHU
• Alarm no. 43 - Supply duct 100% open
• Alarm no. 44 - Exhaust duct 100% open
• Alarm no. 48 - Negative Pressure
ADAPT Parasol
• Alarm no. 10 - Low nozzle pressure
• Alarm no. 25 - Comfort alarm: Heat
• Alarm no. 26 - Comfort alert: Cooling
• Alarm no. 28 - Comfort alert air quality
Disabling alarms
In all the CONTROL and CONDUCTOR products, it is now possible to disable alarms. Alarms should normally not
be possible to disable because they are there for a reason (indicating that something is wrong in the system).
However, there may be cases where a facility is incorrectly configured, for example, an old ventilation system
which does not achieve the standard that our products expect, which will result in an alarm. In many cases the
system weaknesses are known, the products are working well individually, the indoor climate is within reasonable
limits and the deviations are accepted by the customer. It is then possible to disable alarms regarding these discrepancies. This avoids unnecessary alarms being displayed.
The alarms which should be disable in the CONTROL and CONDCUTOR products are easily blocked by setting the
delay time of the alarm to ”0”. This is performed through TUNE Control / CONDUCTOR RU or by downloading a
new parameter file with chosen values already blocked.
Alarm e-mail
In Super WISE there is the possibility to send an e-mail, sent to pre-set email addresses, when critical alarms occur.
Every five minutes the Super WISE checks the alarm system, if a critical alarm has occurred an e-mail is sent to
selected addresses. There is also a function to send a test e-mail to the selected receivers to make sure the settings are correct. See page 12 for more information.

Classification of alarms
Classification of the alarms in A- and B-levels are introduced in the WISE system. This means that the alarms
which the customer considers to be significant will be classified as A-alarms, these alarms will always appear in
the Super WISE tree structure and a notification will be sent to the selected e-mail addresses. The alarms which
are considered less significant will be classified as B-alarms. The customers can choose in the Super WISE web
page how alarms should be handled. The following options are available:
• Always show A- and B-alarms
• Hide B-alarms in the alarm summary and in e-mails
• Hide B-alarms both in the alarm summary and for each individual room view in the Super WISE
Delivered from factory, the Super WISE has all function alarms, such as sensor failure, damper stuck, set as
A-alarms. All the comfort alarms, such as incorrect temperature are set as B-alarms. After delivery, the user can
choose exactly which alarms should be set as A-alarm and which should be set as B-alarms in the Super WISE
webpage. To change the classification the user selects an alarm in i.e. the B column and click the arrow pointing
to the A column to make it an A-alarm. The alarms will then change priority from B to A for all products, where
the alarm is relevant, see red marking in figure 11. The same procedure is applicable when an A-alarm should be
changed to a B-alarm.
Figure 11. Classifications.
Clearing the alarm history
With WISE Care Package 1 it is possible to clear the alarm history of the alarms which have been reset, see the
blue marking in figure 11. It is also possible to clear all alarms, Super WISE will then reload all active alarms, see
the yellow marking in figure 11.
Removed alarm
Former alarm no. 10 - ”Low battery in room unit” is removed for all zone products as this alarm serves no purpose.
One readable alarm parameter for communication
Previously, a BMS / PLC had to read all alarm parameters in Super WISE to check if there was any alarm in the
system. To save time for the BMS / PLC integrator there is now one readable parameter which indicates if there is
any alarm in the WISE system.

Dividing the air flow
Previously, when creating air flow sum slaves in the Super WISE on zone level to sum a number of supply air
dampers to several extract air dampers, the extract air dampers received equal amount of the summed air flow as
set point.
With WISE Care Package 1 it is possible to set how much percentage of the total air flow sum each extract air
damper should have as a set point. This allows for different sized ducts and dampers on the central exhaust air
dampers, even a combination of circular and rectangular dampers is possible. All settings are easily configured on
the zone page.
For example, the total summed flow from the supply air dampers is 2000 l/s, we have three extract air dampers,
where we want this sum flow as set point. The extract air dampers have following sizes: 400 mm, 500 mm and
600 mm. We set the percentage flow to the extract air damper with size 400 mm to 27%, the damper with size
500 mm to 33%. The left over percentage will automatically be assigned to the remaining damper. The damper
with size 600 mm will hence get 100 -27-33 % = 40% of the total sum flow.
►►
Time and date settings in Super WISE
Since Super WISE log function is very comprehensive and log data up to 999 days, it is important that the time
and date are set correctly in the Super WISE. When the user logs on to Super WISE, Super WISE checks if its own
internal time setting deviates from the user’s computer. If the settings differ, Super WISE will automatically update
its internal clock to the user’s system clock. This ensures the setting for time and date is always up to date
►►
Communication scanning
When the user manually push the ”Scan” button (in the Admin tab -> Misc.) to initiate a scanning of new products in the WISE system, a counter starts (marked in red in figure 12) counting from 0-100%. When the counter
reaches 100%, the scan is completed.

Super WISE webpage
The Super WISE webpage has a number of updates. All parameters and readable values which are not relevant
to the current operating mode are hidden until they become relevant. For example, if the CAC feature is disabled
on an ADAPT Damper the settings and values are not displayed for CAC function in the Super WISE. When the
CAC function is enabled, these settings and values are displayed in the Super WISE webpage. See example below
marked with red.
