Model Predictive Control
Model Predictive Control
tado° does not require presence or absence time programing. Patents have been led
for the algorithms which automatically adjust the heating output to the user‘s needs. A
building model is automatically created for each household to enable tado°‘s proprietary model predictive control to include weather forecasts into the control strategy as
well and to thus optimize the energy demand and comfort at home.

Mobile and Web App UI
Mobile and Web App UI
tado° is built for mobile phones and web use. Accordingly, tado° settings are most
comfortably controlled using the tado° mobile app. It is available for iOS (> Version
7.1), Android (> Version 2.3) and Window Phone (> Version 8.1). The download is free.
Besides control of settings and management of data, the tado° app also provides a
detailed report of the heating history and a feature to compute a savings estimate.
The tado° Web App is accessible on computers and tablets and contains the same
features as the mobile app.
Heating Operations
There are three different heating operations.
AutoOff
Off: When set to Off, tado° only heats when the room temperature drops below 5°C to
advoid frost damage.
Auto: When set to Auto, tado° controls your heating based on your location and schedule. You can adjust your prefered home and sleep temperatures. The optimal away
temperature is set by tado° automatically.
Manual: When set to Manual, tado° keeps the room temperature at the selected set
point.
Hot Water
For hot water there are four operations.
Off Auto ManualSchedule
Manual
Off: When set to Off, no hot water is prepared.
Auto: When set to Auto, tado° prepares hot water when you are at home.
Schedule: When set to Schedule, tado° prepares hot water according to the settings
in the dedicated hot water schedule. It can be set in the web application.
Manual: When set to manual, tado° prepares hot water constantly.

Smart Thermostat UI
tado°s Smart Thermostat has a user interface which is activated by pressing the button
on the bottom right. First the current temperature is displayed. The mechanical button
on the bottom right can be used to ip through the menu. The next press switches
to the Operation / Mode screen. After pressing the button once more, the setpoint
temperature is displayed and can be adjusted using the cap-touch buttons, which light
up when settings can be changed. On heating systems that support hot water prepe-
ration, the current hot water state (on/off or temperature on specic systems) and hot
water operation are accessible by pressing the mechanical button again.

tado° Bridge

The tado° Bridge is the intermediary device between a tado°
Smart Thermostat and the tado° Servers. It is connected to a
router via an ethernet cable and communicates wirelessly with the
Smart Thermostat.
Connecting the Bridge
Connecting Checking
1
Connect the ethernet port to the router
and the USB port to power via the power
adapter.
link

internet
2
The Bridge should be connected and
checked before proceeding with the
installation of the tado° Smart Thermostat
and/or the Extension Box. The “router” and
“internet” lights must be solid.

TROUBLESHOOTING: If the Bridge is unable to connect to the router (“router” light
continues to ash) or to tado° servers (“internet” light continues to ash) check the ethernet cable and/or reset the device by unplugging and plugging the power cable back in. If
the Bridge is still unable to connect, there may be an issue with the conguration of the
router. More information is available at tado.com/support.

tado° Smart Thermostat
The tado° Smart Thermostat replaces existing thermostats
or acts as a wireless thermostat together with the tado°
Extension Box for heating systems that do not yet have a
thermostat. It measures room temperature and allows to
modify operation and set point temperature. If it is wired to
the boiler it directly controls the heating. If is is not wired, it
communicates to the boiler via the tado° Extension Box.
The tado° Smart Thermostat is powered by three AAA batteries which are included in the package. The paper strip must
be removed from the thermostat to activate the power supply. Batteries typically last for two years. tado° will inform you
via email and/or push notication when it is time to replace
the batteries.
Correct Placement of the Smart Thermostat
In those cases where tado° Smart Thermostat does not replace an existing wired
thermostat, it can be placed in any appropriate location. When installing the Smart
Thermostat please observe the following points:
• place the Smart Thermostat in a location which is representative for the temperature which should be set. This is usually the living room
• place the Smart Thermostat on an inside wall at approx 1.5 m from the ground
• do not place the Smart Thermostat in a place where it is exposed to direct sunlight
at any time of the day
• place the Smart Thermostat away from any draft (near a door or window) or heating sources such as radiators or electric devices

tado° Installation
i
tado° provides installation instructions specic to every heating setup. Those
instructions are provided as online webow. This documentation at hand is no
replacement of these instructions and is a documentation of tado° devices and
features, not of the installation process itself.
WARNING: While the self installation of the tado° system is possible, tado° strongly
recommends booking of a professional installation by one of our tado° installation professionals.

System Components – tado° Smart Thermostat
Wiring
tado°s Smart Thermostat supports both 230V and low voltage interfaces. The wiring
diagram on the back of the device shows the wiring for the relay operation, three isolated parking slots for excess wiring (from the thermostat which is to be replaced) and
three low voltage terminals for analog and bus connection.
When replacing a relay thermostat, connect COM and NO and optionally NC (if
present in the current thermostat). Place any additional wires, such as a neutral wire
into the parking slots without labeling next to the relay terminals. They do not have any
function other than safely parking excess wires.
To replace an analog thermostat, use the three low voltage terminals on the right hand
side. The analog output is connected to “A”, ground (GND) to “-” and the positive input
(Vcc) to “+”.
When replacing a two-wired digital thermostat, the two low voltage terminals labeled
with “-” and “+” are used. Typically digital bus interfaces are protected against polarity
reversal, thus the order of connection does not matter.
A
TROUBLESHOOTING: The tado° Smart Thermostat can be reset by pressing the but-
ton on the front for more than 8s.
When replacing wireless thermostats, the additional purchase of the tado° extension kit
is recommended. tado°s Extension Box replaces an existing external reciever, extenal
controller or is connected directly to the boiler. The tado° Smart Thermostat can then
be placed in any suitable location without any wired connection being required.

System Components – tado° Extension Box
tado° Extension Box
The tado° Extension Box acts as a communication link
between the tado° Smart Thermostat and the boiler. It
replaces extenal controllers, external receivers or is directly connected to the boiler.
The Extension Box is powered by 230V mains connection
for relays and by low voltage power supply when connected
to analog or digital interfaces. For potential free relay wiring,
an additional two wire power supply cable maybe required
which is provided by tado° upon request.
Wiring
tado°’s Extension Box has both 230V and a low voltage interfaces. Two relay wiring
congurations are possible and are distinguished by two different jumper positions.
The rst wiring option is a potential free wiring connection, where the power supply is
separated from the relays. This wiring option is to connect low voltage single relays.
In case a UK standard backplate is present and wired as a 230V dual relay (central
heating and hot water) the tado° Extension Box can simply be mounted on the existing
backplate and does not require any rewiring.
For UK standard backplate where only one relay is wired, some rewiring might be
required such that the wires correspond to tado°s “Relay Wiring 1” as indicated at the
back of the Extension Box.

TROUBLESHOOTING: The tado° Extension Box can be reset by pressing the button on
top for more than 8 seconds. After a reset, the box will start to look for a connection to the
tado° bridge and the LED will blink during that process.
