General information Important information CAUTION Do not turn on the power supply for the unit until the hot-water tank and central heating circuit is filled with water. WARNING The electric boiler for the central heating must not be activated until the system has been filled with water and the cen- tral heating circuit has been vented.
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...
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 set fan speed level will If you press current room temperature, the set room tempera- be displayed.

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 change 1. Before opening the door, turn off the unit on the user 2. Turn the thumb screws in the door at the top of the unit panel under ”Unit on/off” in the settings menu. 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.
Check air intake and discharge It is important for operation of the unit that air can freely move through the air intake and discharge. If roof stacks have been fitted to the air intake and discharge, check that they are not blocked with birds' nests, leaves or other dirt which can hamper air passage.
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. >...
Show data You can access current operational data for the ventilation unit. This will allow you to check that the unit operates satisfactorily and to identify the cause of potential alarms. > Show data > Operating state Description: Shows the operating setting in which the unit is running. >...
Week programs You can program the ventilation unit to run in accordance with specific settings at fixed times during the day and week via a week pro- gram. On the main screen of the control panel, in the top right corner, the Week program icon will be displayed when active. >...

Cooling The unit can cool the dwelling by active cooling via the heat pump. The unit will only switch to cooling mode if you have activated Cooling in “Operation mode”. Active cooling: If the room temperature, measured in the extract air, is higher than the desired room temperature + the cooling setpoint, the compres- sor will start up and begin active cooling of the supply air.
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.
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. >...
Condenser curve control Supply air [%] Condenser temperature [°C] 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.
Temperature regulation In the temperature regulation you set the supply temperature as requested for the summer and winter operation. Furthermore the outdoor temperature has to be set for the shift between summer and winter operation. ATTENTION During periods when heating is not required in the dwelling, the supply air temperature may fall below the minimum temperature.
Alarm list VP18 M2 EK 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.

Troubleshooting Emergency mode Emergency mode domestic hot water If an error occurs in the control system or components in the VP18 M2, and the unit therefore stops, it will not be able to produce do- mestic 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.
