Introduction The following instructions are general and apply to all Nilan ventilation units. Some of the shown functions and settings may therefore not exist on your ventilation unit. The user settings that are applicable to exactly your ventilation unit will more or less correspond to those displayed in the Nilan User APP on your phone.
Temperature 1. Press “back” to return to the previous page. 2. You can set the room temperature by scrolling up or down with your finger on the icon. When the ventilation unit is operating in heating mode, the thermom- eter is red. In cooling mode it is blue, and during neutral operation orange. 3.
Air humidity 1. Press “back” to return to the previous page. 2. Here you can set the value for low level of humidity between 15– 45%. 3. Here you can set the fan speed level for low humidity between level 1 – 3. You can also deactivate the function.
Filter replacement 1. Press “back” to return to the previous page. 2. Here you can set the amount of days between filter replacements. 3. Here you can reset the alarm for filter replacement. 4. Here you can turn off the ventilation unit before filter replacement and turn the unit on again afterwards.
Control panel Control panel functions Main screen items The main screen of the HMI panel shows the information and the settings options that a user mostly requires. 1. Shows the current room temperature in the house, measured via the extract air 2.
Main screen settings options The settings options that are necessary in daily life can all be set on the main screen of the panel. If you press current fan speed level, the set fan speed level will If you press current room temperature, the set room be displayed.
Settings menu overview The settings menu is constructed to make it easy to navigate through. You navigate through the settings menu by pressing the arrow below or above. If you want to access a menu, tap the text for that menu and it will open.
Generally A ventilation unit from Nilan can last for many years if it is properly serviced and maintained. Ventilation units are often hidden away, and they are therefore rarely given attention in everyday life. But just as you maintain your car, your ventilation unit will need servic- ing regularly to keep it functioning properly.
Illustration of filter replacement 1. Before opening the door, turn off the ventilation unit on 2. Turn the thumb screws in the door at the top right of the control panel under “Operation” in the settings menu. the unit and open the door. 3.
Annual maintenance General cleaning The ventilation unit should be cleaned on the inside once a year. Dust may escape through the filters and potentially mix with moisture from the extract air. WARNING Stop the ventilation unit on the control panel and switch off the power supply for the ventilation unit before you open the front door to the unit.
Heat exchanger The counterflow heat exchanger is a central part of the ventilation unit. It heats up the cold outdoor air with energy from the warm ex- tract air. To maintain a high level of heat recovery, it is important that the heat exchanger is not clogged with dirt. Experience indicates that it should not be necessary to lift out and clean the heat exchanger every year.
User settings Setting the ventilation unit Turn off the ventilation unit If you need to open the doors to the ventilation unit in connection with servicing or filter replacement, remember to turn off the venti- lation unit. You do this under the menu item “Operation”. When the ventilation unit is off, this icon is displayed on the main screen of the control panel in the top righthand corner.
Alarm You can read off warnings and alarms under the “Alarm” menu item. This is also where you reset them once the problem has been solved. If an alarm or a warning is active, the alarm icon will be displayed in the upper righthand corner of the control panel. >...
Date/time It is important to set date and time correctly. It makes it easier to trace potential faults when an error is being reported. When logging data, it is important to be able to follow the history. You set the time in the settings menu. >...
Eftervarmeflade Dette menupunkt er kun synligt, hvis der er installeret en el- eller vand-eftervarmeflade, og den er aktiveret under serviceindstill- inger. En eftervarmeflade er ikke standard, men kan købes som tilbehør, og kan også eftermonteres, hvis det skulle ønskes. Hvis det ønskes at styre tillufttemperaturen (indblæsningstemperaturen) er det nødvendigt at installere en eftervarmeflade. Det giv- er mulighed for at styre tillufttemperaturen uafhængig af udetemperaturen.
Humidity control The primary purpose of ventilation is to extract humidity from the house so it does not damage the building, and to achieve a good in- door climate. This is rectified by an integrated humidity control system that maintains good, relative air humidity. When the average air humidity in the house falls below a set level (default set at 30%), ventilation may be reduced.
Control This menu is only displayed if a CO -sensor has been installed, and the function has been chosen under Service settings. ATTENTION A CO sensor is not a standard part of all ventilation units, but may be purchased as an accessory. If the number of people using a building varies considerably, controlling ventilation through the CO level in the extract air may be a good solution.
Filter alarm ATTENTION It is important to change the filters regularly and when needed. Dirty filters reduce the efficiency of the ventilation unit and result in a poorer indoor climate and higher power consumption. From factory, the filter alarm has been set to signal filter replacement every 90 days. You can set the timer to fit the level of pollution in the area where the ventilation unit has been installed.
Temperature regulation If you have not installed an after-heating element, use the settings to control the bypass damper. It is necessary to install an after-heating element if you want to control the supply air temperature and for it to contribute towards the heating of the dwelling.
Alarm list Combi The following list applies to Compact ventilation units with the CTS602 control. The events are divided into the following categories: Warning Operation continues, but an incident has occurred that should be kept in mind. Alarm Operation is partially or completely stopped as it is a critical fault that needs immediate attention. Type Display text Description / cause...
