General information Safety Power supply CAUTION Always disconnect the power supply to the unit if an error occurs that cannot be rectified via the control panel. CAUTION If an error occurs on electrically conductive parts of the unit, alway contact an authorised electrician to rectify the error. CAUTION Always disconnect the power to supply to the unit before opening the unit doors, for instance for installation, inspection, cleaning and filter change.
ATTENTION When contacting Nilan with questions about the product, it is important to have the unit name and serial no. (SN) ready. From this information, the service department can find all information about the unit in question and thus help with information and answer questions about what the unit consists of/contains, and what software is used.
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.
Domestic hot water 1. Press “back” to return to the previous page. 2. If you scroll down with your finger, you can read off the current temperature of the hot water. 3. You can set the domestic hot water by scrolling up or down with your finger on the icon.
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 Functions in the control panel 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 which the user needs in daily life can all be controlled from the main screen of the panel. If you press current fan speed level, the If you press current room temperature, If you press the current hot water tem- set fan speed level will 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.
General information 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. Tilt the upper door outwards, pull it up and put it to one the control panel under “Operation” in the settings menu. side. 3. Loosen the thumb screws in the next door and put the 4.
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.
Checking sacrificial anode A sacrificial anode is mounted in the hot water tank (not in stainless steel tanks) to protect the tank from corrosion. The sacrificial an- ode is electrically monitored and it is important to replace it immediately after an alarm is detected in the control panel. It depends on the water quality, installation and consumption how long it will take between replacements.
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. >...
> Unit type Description: Shows what type of ventilation unit it is. > Software version Description: Shows the software version of the ventilation unit. > Panel software Description: Shows the software version 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.
Supply air heating This menu item is only visible, if a after heating element is installed and activated in the service menu. ATTENTION A after heating element is not standard, but can be purchased as accessory and can be retrofitted if wanted. When the room temperature (measured in the extract air) falls below the desired room temperature set in the display, the heat pump and the after heating element will start heating the supply air.

After-heating element You will only have this menu item if an electrical after-heating element or a water after-heating element has been installed, and if it has been activated in “Service settings”. ATTENTION An after-heating element is not included as standard. However, you can order it as an additional extra, and it can also be retrofitted.
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. During long periods with sub-zero temperatures, air humidity in the house may fall to a level that is critical for the build- ing and for the indoor climate.
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.
Air exchange You can prevent low humidity in the dwelling by reducing ventilation at low outdoor temperatures. This function is useful for instance in countries with regular frost or at high altitudes in the mountains where the outdoor air is very dry. >...
> Low temp. compr. start Settings: 0 -15 °C / Off / 0 15 °C Standard setting: Description: Here you indicate whether the heat pump is to start up at low outdoor temperatures, even if heating is not required. Off means that the function is deactivated.
Temperature control 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 Compact Alarm list 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.

Contact service if the unit does not operate This may be due to a prolonged power cut to your satisfaction/ as before, as some or a lightning strike.
Emergency mode Emergency mode domestic hot water If an error occurs in the control system or components in the Compact P2, and the unit therefore stops, it will not be able to produce domestic hot water. If the installer is not able to come right away or the error happens outside the opening hours, and you therefore cannot contact the in- staller, there is a possibility to get hot water by setting the unit into emergency mode.
