CONTROL SCREEN ELEMENTS
Current temperature
-
Displayed at the top of the screen.
-
The value is read directly from the KNX datapoint.
-
Units are shown in either °C or F, depending on system settings.
Status icon – Heating/Cooling
-
A dynamic icon indicates the current operating state.
-
The icon changes based on the relationship between the current temperature and the setpoint, and the selected mode:
|
Condition |
Mode |
Icon |
|---|---|---|
|
Current temperature > Setpoint |
Cooling |
 |
|
Current temperature > Setpoint |
Heating |
 |
|
Current temperature < Setpoint |
Cooling |
 |
|
Current temperature < Setpoint |
Heating |
 |
Setpoint temperature
-
Displays the current target temperature.
-
The value is read from the datapoint.
-
Shown in °C or °F.
Mode button
-
Displays the currently active mode (e.g., Comfort, Eco, Night).
-
Tap the mode icon
to open the mode selection screen.
-
Select the desired mode and tap Set to confirm.
Fan button
-
Displays the current fan status:
-
ON (with selected mode)
-
OFF
-
Auto
-
-
Tap the fan icon
to open the fan mode selection
screen.
-
Select the desired fan mode and tap Set.
-
To turn the fan off, deselect the currently active mode.
Cooling/Heating toggle
-
A simple toggle button
that switches between cooling and heating modes.
On/Off button
-
The On/Off button
controls the overall state of the thermostat. It turns the
RTU (room temperature unit) on or off. This button does not control
any actuator directly; instead it disables the logic inside the actuator,
which stops the RTU from functioning. -
When the button is ON, all interactive elements (buttons, sliders) are active.
-
When the button is OFF, the widget becomes inactive and settings cannot be changed.
-
The On/Off button can be mapped to control other functions, such as heating/cooling. For example, if it is mapped to air conditioning (heating/cooling), switching it OFF will stop the AC until it is turned back ON.
-
Even when the On/Off button is set to OFF, the Follow schedule and Manage schedule features continue to work as usual.
NOTE: This feature is only available in the generic thermostat. It is not supported for the Danfoss thermostat or the VDC thermostat.
Custom Modes
The thermostat allows you to configure up to six custom modes, which extend the functionality beyond the standard modes like Comfort, Standby, or Sleep. These custom modes are useful for tailoring the thermostat’s behavior to specific user needs or scenarios.
Each custom mode must include:
-
A unique name – used to identify the mode in the app.
-
A mode value – the value sent to the system when the mode is activated.
-
A mode status – a status value that is used for feedback or logic in the system.
Adding and Managing Modes
-
To add a new mode, click the Add another mode button.
-
Fill in the Mode name, Mode value, and Mode status fields.
-
To remove a mode, click Remove this mode next to the specific mode you want to delete.
Using custom modes is optional – they are enabled by checking the Use custom modes box in the thermostat General settings.
