Switching off your boiler and corresponding circuit breaker
Make sure that you take steps to ensure that the power
supply to your boiler is completely switched off and
remains switched off during the installation process. In
addition it is compulsory to remove the breaker/fuse that
your boiler is connected to, or turn of the corresponding
switch in your circuit breaker box.
If you are not 100% sure which is the
correct switch/breaker/fuse then you
must remove all breakers/fuses or turn
off the main power switch in your circuit
breaker box.
Please leave a message at the circuit breaker box such
to inform everyone not to turn anything back on.
Please make sure that all residents of the
home are aware that you are going to turn
off and that you are the only one who is
allowed to switch it on again.
Please be aware that your desktop computer
and lighting will turn off when you switch off
the mains power circuit breaker switch.
To provide safe lighting for the installation you
can use the flashlight function of your
smartphone or a torch.

Open your boiler to get access to its control unit
Access the boiler control by opening the boiler. Since every boiler has a different opening method, take a look at our examples below to get an idea how your boiler can be
opened. All wiring connection terminals are found on the control unit. You will be looking for the place where lots of wires connect to the boiler. Look for the terminal where a room
thermostat can be connected. The installation manual of your boiler very often helps.

Make sure the power is off
Use the voltage tester to check if there is still power on
any wiring terminal.
If there is any light it means that there is still power on the
wiring. Before continuing, switch off the circuit breaker.
If there is no light, power is off and it is safe to proceed.

Documenting the wiring of the existing setup
As soon as you have removed the cover please take detailed photos of the existing wiring with the cables still attached. Try your best to make the terminal numbering legible.
This step is very important, you will definitely
need this information in the future. Should
you need help, it will be difficult for our
Technical Support Team to assist you
without the photos of all of the current
wiring.
You will need these photos to restore
your old system if you move house in
order to take your tado° with you. Please
save them in a place where you will find
them again in this case.

drilled. Ensure the holes are deep enough so that the
rawplugs do not protrude from the wall and therefore
prevent the correct mounting of the tado° Extension Kit
