4.2 External temperature probe
Depending on how it is configured, the external temperature probe can be used to accomplish several
functions (see par. 9.6); it does NOT have polarity so you can connect the 2 wires in the 2 terminals
without any particular order.
It is recommended to use the NTC 10k beta 3900 probe (art. 02965-20432-19432-14432).
The typical wiring diagram is the following:

6. Configuration via WiFi interface
The timer-thermostat 02911 features a WiFi interface that lets you configure and control your device remotely.
To function correctly, the WiFi interface must be properly configured by performing the first configuration pro-
cedure described in the next paragraph (6.1).
6.1 First Configuration
•First identify the make and model of the client Gateway/Router and keep note of them as a reference
for any official Vimar support (use the specific table in section 17).
• If there is already an Internet connection at the site of installation, make sure the Gateway/Router has been
turned on for at least 2 minutes and is connected to the Internet.
• Make sure the timer-thermostat is installed at a reasonable distance (from the router), where the
signal is strong enough.
• Activate configuration mode; in this phase the timer-thermostat acts as an access point, generating a
specific temporary WiFi network for the configuration with no need for an Internet connection.
6.1.1 Activating configuration mode
1. On the main screen, access the Settings menu by tapping the icon.
2. Using and scroll through the list of options until you see .
3. Confirm by touching
4. Check that the “OnOF” option is set to “On”; the display must show the following screen
exactly (“OnOF” flashes and “On” is on steady):

8. Confirm by touching
9. The cursor will move from left to right; the icon will blink for a few
seconds and will be fixed once the access point is active. The timer-thermostat is then ready to
be configured via the By-clima App.
10. From this point onwards, configuration will continue directly via the mobile device (e.g. smart-
phone) through the By-clima App (see par. 6.1.2).
11. If necessary, the configuration procedure can be interrupted at any time by one of the following
options:
a. tapping
b. closing the By-clima App
c. when the mobile device (e.g. smartphone) goes into standby.

CAUTION: At the end of the first configuration procedure, the timer-thermostat and the mobile
device with which you performed the procedure will be paired. The timer-thermostat 02911 can
then be controlled (via WiFi) only by the mobile device with which it was configured. If you wish
to control the 02911 also with other devices then you need to carry out the pairing procedure for
additional devices described in paragraph 6.4.
6.2 Configuring the temperature control parameters and using the device
If your mobile device has been properly paired with the timer-thermostat, you can set the temperature control
parameters (temperature profiles, setpoint, etc.); the By-clima App clearly displays all the instructions in a
user-friendly manner for making the desired settings.
After these settings, send the configuration to the timer-thermostat or proceed to configure the network
parameters as shown in the next paragraph (6.3).
6.3 Configuring the WiFi network and cloud services
The network parameters should be configured during initial installation and/or if you change the network cre-
dentials with which the timer-thermostat connects to your home WiFi.
Using the By-clima App, you enter the section shown in the figure on the next page and proceed by entering
the parameters with which the timer-thermostat will connect to your home WiFi network (network name, pass-
word, address assignment method, etc.).
To enter the parameters follow the guided procedure displayed by the By-clima app.
After making the settings, the timer-thermostat will automatically reboot the network interface and, with a
specific icon as shown below, it will show the state of its connection to the WiFi network:

- absent: WiFi antenna of the timer-thermostat off (to turn the WiFi interface on or off, see par. 9.11.1)
- blinking: timer-thermostat connecting or not connected to the local WiFi network (if prolonged it
indicates a possible error in entering the password/network name or no WiFi router signal).
- (bars from 1 to 4): timer-thermostat properly connected to the WiFi network and its signal strength.
In addition to configuring your home network you can also specify whether you want to take advantage of the
Vimar cloud service.
6.3.1 Cloud Service
Vimar lets users easily access their timer-thermostat from all over the world over the Internet thanks to
its cloud service.
This service enables:
• Fully controlling your timer-thermostat from all over the world.
• Receiving notifications from your timer-thermostat directly on your mobile device.
• Updating the timer-thermostat software.
• Saving all the timer-thermostat settings should you need to replace it.
Registration with the Vimar cloud is automatic and is linked to the timer-thermostat (creating a user is
not required: no login).
By pairing a mobile device with the timer-thermostat, the smartphone/tablet is merged (at the logic level)
with the registration of the timer-thermostat in the cloud (see par. 6.2).
6.3.2 Use without the cloud
If you do not wish to register on the cloud, the timer-thermostat can still be set to run without the cloud
(for example, only via a local WiFi network without the Internet).
Not activating the cloud will prevent you from doing the following:
• Operating the device over the Internet (control only within the local WiFi network)
• Receiving software updates
• Receiving notifications from your timer-thermostat on your mobile device
• Saving all the timer-thermostat settings should you need to replace it.
NOTE: We recommend the installer keep the timer-thermostat in this operating mode and let the
customer choose whether to use the Vimar cloud.

17
6.4 Pairing additional mobile devices with the timer-thermostat
The timer-thermostat 02911 can be controlled only with mobile devices that have been paired with the first
configuration or pairing procedure.
A new mobile device (on which the By-clima App has previously been installed) can be paired at any
time by using the By-clima App on the mobile device itself but only by also interacting with the local
interface of the timer-thermostat (see par. 9.11.5) and within the same WiFi network (you cannot pair
mobile devices remotely/over the Internet).
When pairing, you are prompted to enter a 4-digit PIN code to pair the mobile device with the timer-thermostat,
which can only be controlled if:
- the mobile device is paired with the timer-thermostat;
- the PIN code of the mobile device and that of the timer-thermostat coincide.
If you change the PIN of the timer-thermostat but not that of the tablet/smartphone, the mobile device (which
is still set to the old PIN) will no longer be able to manage the timer-thermostat; it will then be necessary to
update the PIN of the tablet/smartphone device(s).
CAUTION:
•The PIN for accessing the timer-thermostat 02911 from your mobile device can only be changed with
the By-clima App.
• The PIN code is very important because it protects the timer-thermostat from previously paired
mobile devices too (eg that of the installer). The end user is advised to change the default PIN code
so as to disable control of the device from all smartphones/tablets (even if already paired with the
device) that do not have the updated PIN code.
