1 Installation
To configure and operate the ComfoClime the user must install the ComfoClime Control app by
downloading it from Google Play or Apple Store.
Once installed the app will appear among the phone apps with it's icon:
All the manuals are downloadable scanning this QR-code.
You’ll be redirected to the download page where you can select
among a wide range of languages.

2 The provisioning
At the first launch of the app, the user will be prompted to detect the ComfoClime and connect it to
his home WiFi network (if available).
The ComfoClime can be controlled only through the ComfoClime Control app.
In case the user doesn’t have a WiFi network running in the house there is the possibility to get
connected to the ComfoClime anyway through the Bluetooth connection or through a local WiFi
network generated by the ComfoClime itself.
ACTION IMAGE
Launching the APP the installation page, called
Apartment select, will appear.
To begin detecting the ComfoClime, proceed
by tapping the ADD button.

ACTION IMAGE
In the next page the user is asked to select
between a WiFi present or not can choose
whether to go for a brand new installation or
connect an already installed ComfoClime.
Advise: please ensure in your mobile phone WiFi
settings that your WiFi allows to add additional
devices.
Note: check also if the router allows to add other
devices to the local network and in case, enable
the feature.
In the first provisioning screen there are two
possibilities:
YES: the user will install the ComfoClime in the
WiFi network searching the unit via Bluetooth.
NO: the user will install the ComfoClime using
a local direct WiFi connection between the
smartphone and the unit (go to pag. 7).
WIFI PRESENT
Answering YES (Step 1) the following page allows
the user to connect the smartphone to the WiFi
in case it wasn’t yet done, firstly tapping on Go
To Wifi Settings and going temporarily in the
smartphone settings to set up the wifi connection
Afterwards, in any case, tap on Next to move to
the next step.

Step 2: the app asks the user to check and
confirm that the smartphone has the Bluetooth
enabled. Once confirmed tap Next.
In this page please confirm the authorization
to use also the geolocation in order to let the
smartphone looking for the ComfoClime tapping
on Grant.

ACTION IMAGE
When the app finds a Bluetooth signal (the one
generated by the ComfoClime), it will show it and
the user must tap on New Device to trigger the
connection phase between the two devices.
The app will move automatically to the next step.
In this page the user confirms the authorization
to the Bluetooth pairing tapping on Pair.

In this page it is possible to assign the WiFi
connection to the ComfoClime among the ones
found in the environment (usually in a house
there is only one)
Important: insert the user’s WiFi router password.
Once the WiFi is chosen the app moves to the
next page.
WiFi Home
Tap on Next.

The next page recap the installation successfully
done showing the configured unit with its
name and a green dot that means it is properly
connected.
To enter the ComfoClime controls just tap
over the name of the unit.
Important: this feature is useful especially if
the user owns several ComfoClime in different
houses so that he can use the same app to
control all of them. The active system is visible
by the green dot. All the others should have
the red dot because it is normally assumed
that there is only one ComfoClime in the
building. Otherwise the user will see a green
dot for each ComfoClime actually present.

option to change the access level.
There are three different possibilities:
• Basic: default user level. All the main
functions are active for a normal use and
control of the unit.
• Advanced: tapping on it and confirming with
Enter button the user has access to many
further parameters of the Thermal profile
concerning the settings of the heating and
cooling functions.
Warning: changing these values can be very
detrimental for the proper functioning of the
ComfoClime so it is recommended not to change
them if not completely sure (and responsible
for) but leave this job to authorized and skilled
personnel.
• Installer: tapping on it, typing a PIN code
and the ACTIVATE button, the installer has
access to further more parameters that
deeply affects the ComfoClime behaviour. As
for the advanced level it is strongly suggested
to not change these values leaving that duty
only to the installer or other Zehnder Service
technicians.
Warning: changing these values can be very
detrimental if not lethal for the proper functioning
of the ComfoClime and the access to the Installer
level is permitted only to authorized personnel.

6 The thermal profile
ACTION IMAGE
The Thermal profiler page is composed of two
pages in which it is possible to see and/or set
several parameters, accordingly to the access
level and the model of ComfoClime installed.
Season selection
In Auto mode the season is automatically
detected by the ComfoClime accordingly to the
external temperature and the season settings.
The system calculates by itself the season which
it belongs to, considering an average outdoor
temperature called Tpma.
The Tpma keeps into consideration the
temperature of the past days in order to
determine a “predicted” and consistents current
temperature so not to be misled by sudden
change of the weather. Seasons are defined
by temperature limits (thresholds). The heating
season threshold determines the outdoor Tpma
temperature below which the active heating
is enabled; the cooling season thershold
determines, on the contrary, when the active
cooling is enabled (Tpma above the cooling
threshold). In between there is the middle season
during which the device is disabled so only the
ComfoAir Q provides passive energy recovery.
The user can manage the season in Auto or
Manual mode: in manual, tapping the icons, he
can force the season according to his needs.
The thresholds can be adjusted only by Zehnder
Service personnel during a setup configuration.
The adjustments can be done in the advanced
settings.
Temperature selection
This value represents the setpoint for each
working mode.
In Automatic mode the default values are:
MODE VALUE
POWER 23° heating/23° cooling
COMFORT 21° heating/25° cooling
ECO 19° heating/27° cooling
See the table in the next page for all the default
values.
The Manual temperature adjustment is possible
enabling the advanced profile in the main menu
and the range goes from 18°C to 28°C in both
heating and cooling mode.
