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)
