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 its icon:

5 - EN
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.
ACTION IMAGE
Launching the APP the installation page, called
Apartment select, will appear.
To begin detecting the ComfoClime, proceed
by tapping the ADD button.

EN - 6
ACTION IMAGE
In the next page the user can choose whether
to go for a brand new installation or connect an
already installed ComfoClime.
If no ComfoClime device is listed, the user must
tap over Connect a new device to the WiFi .
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.
If a ComfoClime has already been detected
previously and properly connected the user
should tap on Connect new device than search
for it.
In case there is no WiFi present yet, the user
must tap on the line at the bottom of the page
Advanced configuration (see pag. 10).
Tapping on Connect a new device to the WiFi
the page to the right will show up.
Check if the smartphone has Bluetooth enabled;
if it is enabled then continue tapping on Next.

In this page, allow the ComfoClime Control app
to use your location by pressing Allow once or
Allow while using app.
The app will find the Bluetooth signal emitted by
the ComfoClime and will ask permission to do
the pairing.

Bluetooth signal ("Zehnder_34ab9571dd55" in
this case) by tapping on it.

network simply tapping on it and then typing its
password.

ACTION IMAGE
Once the device appears in the field "Select
your Zehnder hub", tap on it to establish the
connection between it and the WiFi network.
By default the device is named "ComfoClime".
Tapping on the unit's name the user will enter the
actual home page.
A green dot in the right corner indicates the unit
si properly connected and working.
A red dot means the unit is not connected to the
app.

ComfoClimes in the same app (usually
corresponding to different installations in
different houses), only one device per time is
detected and connected with a green dot beside
its icon.

11 - EN

in it and it is possible to finalise the naming
procedure reassigning a new name if desired
and including (not mandatory) an address, city,
country and a customised icon.

2.1 Special circumstances
ACTION IMAGE
If a connection is not possible through WiFi or
Bluetooth, there is a further way to establish the
connection between the app and the unit.
With regard to the initial page (recalled on the
right), at the bottom there is the Advanced
configuration button which allows, if tapped,
to enter in the local “private” WiFi network
generated by the ComfoClime.
By selecting this option, the mobile device will
be able to connect directly to the ComfoClime's
private network. Please bear in mind that in order
to make this connection, the mobile device won't
not be connected to any other WiFi network.
The next page will show the name of the local
WiFi network created by the ComfoClime
called Zehnder_xxxxxxxxxxxxxxxx where
xxxxxxxxxxxxxxxx stands for its serial number.
Before proceeding further with the Search
button the user must check and set the mobile
device on the same WiFi network by tapping on
the Go to WiFi settings and setting the phone
up (see picture beside).

13 - EN
ACTION IMAGE
IMPORTANT: the password to gain access to the
local network is
Zehnder1
Once the mobile device is connected to the same
local network it is possible to continue like in the
procedure for normal WiFi networks choosing
the one called Zehnder_xxxxxxxxxxxxxxxx
among the ones found then confirm the choice
as it is explained at page 7.

proceed entering the Settings page from the
main menu.

unplugging the unit.
Tapping on Settings two new voices will appear:
• Advanced controls;
• Soft reset.
Advanced controls allows the user to have
access to advanced parameters in the thermal
profile in order to customize it according to his
needs (if not strictly necessary it is strongly
suggested not to play or change them).
Soft reset performs a light reset of the device
corresponding to unplugging e re-plugging it.

15 - EN
ACTION IMAGE

controls, it is necessary to enter the PIN 4210
then tap on Next.

A new menu item will appear called Soft reset.
When selecting this option a warning message
will appear recommending the user to wait until
the unit is rebooted completely. Proceed tapping
on Confirm then wait until the end of the reboot
process.
A new voice called WiFi appears when the
Advanced Controls are enabled. I allows the
