Important information before commissioning:
-Please read the complete instructions before starting to install the thermostat.
-The thermostat must be installed by a qualified person.
-Only use the thermostat as described in this manual.
-Always disconnect the power supply during installation work.
Safety notes:
When handling products which are supplied with electrical voltage, the applicable VDE regulations must be
observed, in particular VDE 0100, VDE 0550/0551, VDE 0700, VDE 0711 and VDE 0860.
- Before opening the device, make sure that it is de-energized.
- Tools may only be used on the device if it has been ensured that it is disconnected from the supply
voltage and that any residual electrical charges stored in components have been discharged beforehand.
- Live cables or lines to which the device is connected must always be checked for insulation faults or
breakages.
- If a fault is detected in the supply line, the device must be taken out of operation immediately until the
defective line has been replaced.
If these instructions is not clearly state for non-commercial end users in regard to, which electrical
characteristic values apply to the device, how external wiring is to be carried out, or which external
components or accessories may be connected and what connected loads these external components may
have, a specialist must always be requested for information. Before commissioning the device, check
whether it is suitable for the planned application!
In case of doubt, it is absolutely necessary to consult experts or the manufacturers of the modules used!
Please note that operating and connection errors are beyond our control. We assume no liability for any
damage resulting therefrom.
Description of Device keys and LEDs
1. 1. mode & on/off key, short key press change
operating mode, long key press (3 sec.) on/off.
2. increase temperature
3. short keystroke reduce temperature, long
keystroke (3 sec.) activates pairing mode for
connection to Wlan
Press buttons 1 and 3 for 3 seconds to activate
or deactivate the key lock.

Description Display symbols
Heating symbol:
- Lights up permanently when heating is in progress and
disappears when the target temperature has been reached.
- Flashes if the set limiting temperature of the external sensor is
reached.
Window-Open-
Detection
- Appears if window open detection is enabled. The symbol
flashes if an open window is detected and switches off the
heating. The unit must detect a temperature drop of 3°C within 1
minute for this function to work.
This function is primarily intended for use with the internal
temperature sensor (sensor type 00 or 02). In conjunction with a
pure floor heating system (sensor type 01), it is generally not
practical to use this function.
Optimum start
- Appears if the function has been enabled. With the optimum
start function, the thermostat automatically determines (several
days learning phase required) when the heating must be switched
on so that the desired temperature is already reached at the set
time.
Key lock:
- Is displayed if the key lock has been activated.
Cloud connection:
- Shown if the thermostat has been connected to the cloud via the
app or if there is a connection to the cloud server.
Wlan connection:
- Lights up permanently if the thermostat is connected via Wlan
(see "App integration and programming").
- Flashes if the thermostat has been set to teach-in mode (see
"App integration and programming" point 8).
Manual operation:
- Displayed when the temperature has been adjusted manually
with the arrow keys. This exits the Away-/Home- or Auto-Mode
(weekly program).
Auto-Mode:
- Is displayed if the week program was activated via the app
(Mode: Smart).
Away-Mode:
- Is displayed if the Away mode has been activated via the mode
button on the device or via the app. The temperature set for the
Away-Mode is used.
Home-Mode:
- Is displayed if the home mode has been activated via the mode
button on the device or via the app. The temperature set for the
Home-Mode is used.
Temperature display:
Left: Current room temperature or temperature of the external
sensor (for settings, see manual operation)
Middle: Arrow flashes if the target temperature has not yet been
reached, or if the set limiting temperature of the external sensor
is reached.
Right: shows the desired temperature (set / target temperature)

Manual operation:
The following thermostat functions can also be set without the App.

Set the thermostat to teach-in mode: Press
the down arrow button on the right of the
thermostat for approx. 3 seconds until the
Wlan symbol flashes quickly in the upper
right corner of the display.
Now in the app first tap on "Confirm
indicator rapidly blink" and then on
"Next".

The app now searches for devices that are
in learning mode.
If a device was found, a name can now be
assigned. After touching "Done", the
integration of the thermostat is
successfully completed.
Main view: The setpoint temperature is
displayed in the middle and the current
room temperature (Indoor Temp) above it.
The setpoint temperature can be adjusted
manually using the Plus/Minus button. The
key lock can be switched on/off using the
"Lock" key. Functions of the other buttons
see 13, 14, 15, 18.
Tap the "Mode" icon in the lower left

calibration, hysteresis (Swing) and the
weekly program (Fig. 16).

An individual heating profile can be stored
here.
Here you can select whether only the
internal or only the external sensor is to be
used for temperature determination. It is
also possible to use both sensors in
combination.
By touching the "pen" symbol in the upper
right corner of the main view of the
thermostat, further settings and
integration options in the voice control
systems Amazon Alexa and Google
