Main screen settings options
The settings options that the user needs in daily life are located on the main screen of the panel. You simply press the temperature for domestic water or central heating in order to change it.
When you press the temperature for domestic water, you will see the following panel for the selected setpoint temperature of domestic water:
You can change the hot water temperature by using the upand-down arrows. You then confirm by pressing the confirm icon, bottom right. The main screen of the panel will then be displayed again. If you select the cancel icon, bottom left, the temperature will revert to the original setting. Following this, you have to press the arrow, top left. This takes you back to the main screen.
If you press the temperature for central heating, one of the two panels below will be displayed. Which one depends on whether you have selected a fixed flow temperature for central heating or to regulate via weather compensation:
You can change the setpoint temperature for central heating by using the up-and-down arrows. You then confirm by pressing the confirm icon, bottom right. The main screen of the panel will then be displayed again. If you select the cancel icon, bottom left, the temperature will revert to the original setting. Following this, you have to press the arrow, top left. This takes you back to the main screen.
You can change the selected curve for weather compensation from this panel screen in the same way as described for the `Central Heating' function in `Unit Settings'.

Installer access
Settings menus consist of 3 levels. 1. User level - Settings the user can access and customize. 2. Service level - Settings that the installer needs to access in order to set the ventilation unit in relation to individual installation.
It requires expertise knowledge to select these settings. If the settings are not correct, the ventilation unit may not operate properly and it may consume more energy than necessary. The unit may even get damaged. 3. Factory level - Only Nilan has access.
The Service menu is located at the bottom of the User settings. Tap the down arrow several times to get there.
A password is required to access the Service menu.
You can set the password by using the up-or-down arrows followed by the confirm icon (bottom right).

Unit settings
Turn on unit
When you turn on theheat pump unit, the control panel will light up, but all functions are off. This is to prevent errors from occurring when you turn on the unit.
When the unit is off, this icon is displayed on the main screen of the control panel at the top righthand corner.
ATTENTION Before touching the electrical installations, the power supply must be disconnected.
ATTENTION When the unit is off in the HMI-panel the frost protection function of the unit is still active.
You activate the functions of the unit in the settings menu under the menu item "Operation mode".
> Unit On / Off
> Unit On / Off > Off
Settings: Standard setting: Description:

This is also where you turn off unit when service inspection is to be carried out.
Operation mode
You can set the unit to operate in "Auto", "Winter" or "Summer" mode.
ATTENTION The Winter and Summer functions override the week program. If a week program has been activated, the mode will automatically change to "Auto" at the next shift in the week program.
> Operation mode
> Operation mode > Auto
Settings: Default setting: Description:
Auto / Winter / Summer Auto Auto:The unit is operating according to preset values. At outdoor temperatures above 17°C for 24 hours, operation will switch to summer mode. At outdoor temperatures below 13°C for 24 hours, operation will switch to winter mode. Winter: The unit produces hot water for central heating as well as for domestic hot water. Summer: The unit is set to produce only domestic hot water.

Week program
You can program the heat pump unit to run in accordance with specific settings at fixed times during the week via a week program. For both domestic hot water and central heating, the set point can be moved up or down during selected periods. In this way, the weekly program can work well together with the weather compensation. It is also possible to completely block domestic hot water or central heating in periods.
On the main screen in the top righthand corner of the control panel the icon for the week program is displayed when this function is active.

Smart grid
In some countries Smart Grid can be economically advantageous because it regulates the power consumption of the heat pump in accordance with the price of electricity as it fluctuates in the course of 24 hours. Smart Grid receives an external signal from the power supply company. This determines in which operating setting the unit should run.

Modbus address
The control in NIlan DHW AIR unit has an open Modbus communication, which allows the unit to be controlled with e.g. an external CTS controller.
The CTS602 control communicates Modbus RS485, and the complete Modbus protocol can be downloaded from the Nilan website.

Data log interval
Data can be logged at intervals of 1-1092 minutes.
· Operating data are actual readings or outputs. · Alarms are always logged when an alarm is activated or reset. · An event is either a change of an important setting or a particular operation.
Note! Only installers can download the log file, as an LMT program is required, which can be downloaded on NilanNet.
> Data log interval
> Data log interval
Settings: Standard setting: Description:
1 1092 min. 60 min. If logged with the default setting every hourthe data log can last approx. 1 year.
Data logging In order to data log you need the XML file "Devicelog.xml", which is a decoding specification required by the LMT PC program. The file can be downloaded from NilanNet under the menu item "After Sales/Software".
· Enter the file in the "..\Database" directory under the current LMT project. · You can then retrieve the log from the control system via the menu "Device - Devicelog download". · The log is shown in LMT in both tabular and graphic form. · You can export the log file to Microsoft Excel format.
