General information
Product description
Nilan User App
This App can control those of Nilan’s ventilation units and heat pumps that have a CTS400 or a CTS602 control system. If the unit does
not include a Gateway, you will have to purchase one as an accessory. You connect the Gateway to the Modbus input of the unit. When
you enter settings from the App, it may take a few seconds before the changes are registered by the unit.
The communication from the App to the Gateway takes place via a secure cloud connection. This allows you to access the Nilan unit
from anywhere in the world as long as you have internet connection.

User manual
Nilan User App
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.
If you require a detailed description of individual functions and settings, you can download the software instructions for your
ventilation unit from our website.
Explanation of main screen items
1. On the main screen under the Nilan logo, you will see the number of the con-
nected Gateway.
Under settings, you can name the ventilation unit e.g. Home or Holiday home.
The name will then be displayed instead.
If you have more than one ventilation unit connected to the APP, you will be able
to see to which unit the shown data apply.
Next to the number is a WiFi icon that is green when there is connection to the
unit, and red if the connection is interrupted.
2. Here you can see the items that are relevant to your ventilation unit. If there
are too many items to fit the screen simultaneously, the rest will be below the
displayed items. You can access these by using your finger to scroll up.
If you press one of the items on the screen briefly, a settings menu will appear.
3. Shortcut key to return to main screen.
4. If you press this icon, you will see a list of all current and relevant data.
5. If you press this icon, you will get to a page where you can see a trend curve for
relevant data.
6. Pressing this icon will take you to settings where you will be able to add more
ventilation units.
7. The alarm icon will be displayed if an alarm is triggered on the unit. By pressing
the icon, you will get an outline of the most recent alarms.
If more ventilation units are connected to the same APP, you will have to go into
settings and select unit in order to see to which unit the alarm applies.
