Block Individual room controller

This control element sets the temperature of a room. It shows the measured room temperature and whether heating or cooling is on right now. Switching times lower the temperature at night, for instance, and when leaving the house or during a vacation a separate setpoint can apply.

Operation

Window: the window of the room is open. The controller then does not heat, but protects the room from frost.
Top: the setpoint – depending on the setup.
Centre: the measured room temperature.
Flame / snowflake: heating or cooling is on right now.
Fan: only with a fan coil unit; shows whether the fan is running.

As a circle (basic screen) the element shows the room temperature; the arc tells how far it is from the setpoint – blue means too cold, red too warm, a green dot at the top means: setpoint reached. A tap on the element opens the dialog.

The dialog

Symbols of the title bar: clock, presence, fan coil and settings, see below. The symbol for the fan coil only exists when one is connected.
Ring: dragging sets the setpoint. The centre shows the setpoint and below it the measured temperature (Actual). A tap on the setpoint opens the input.
+ and –: change the setpoint by the set step. If it is larger than 0.1 °C (default 0.5 °C), the setpoint snaps to the next multiple: from 21.1 °C + gives 21.5 °C and – gives 21.0 °C. The ring and the input of the setpoint set any value in steps of 0.1 °C.
Flame / snowflake: heating or cooling is on right now.
Comfort, Standby, Night, Frost: four buttons, each with its stored setpoint. A tap applies the setpoint and closes the dialog. The button whose setpoint equals the set one is lit; if the setpoint is in between, none is lit. To assign a new one, first set the setpoint, then hold the button for 2 seconds.

Switching times and presence

Behind the clock are switching times. Each one selects one of the four buttons – for example Comfort at 6 am and Night at 10 pm on weekdays. The temperature comes from the button: if its setpoint changes, the new one applies at the next switching time. Switching times from older projects that specify a temperature keep working as before until a button is selected. With a fan coil a switching time can also change its operating mode. Everything else about switching times is described under Presence.

Behind the house one of the first three buttons (Comfort, Standby, Night) is set for each state that applies on the change. A tap on a symbol selects whether switching takes place at all for this state; a tap on the operating mode moves on to the next button. The default is Present = Comfort, Absent = Standby, Vacation = Night. In the example the controller changes to Standby when leaving the house and to Night during a vacation. For a control element from an older project the previous temperature is shown there at first and applies until a button is selected.

If switching times or presence are switched on, their entry in the list behind the gear wheel is lit blue and carries the note Active.

Fan coil

If a fan coil unit is connected, its symbol in the title bar opens this dialog. Every selection takes effect immediately.

Stage: Automatic leaves the fan stage to the control, 1 to 3 fix it.
Operating mode: Automatic heats or cools as required, Fan only circulates the air, Off switches the unit off.
Feedback: the stage the fan is running in right now.

Settings

The gear opens the setting Frost protection: the temperature that is kept at least while the window is open.

Setup

This section is meant for the installer of the system.

Two variants

Operation presence – is linked to the function block Room controller block (right mouse button on the control element), which does the control. The addresses sit at the function block and are taken over when linking. Only this variant offers switching times, presence, the four operating mode buttons, fan coil and settings, see Presence. The older block Room controller block (obsolete) can still be linked as well.
Widgets Standalone – without function block, for operating an existing room controller, for instance a KNX device. The addresses are linked directly at the control element. The dialog then carries the text as its heading and offers the four operating modes Comfort, Standby, Night and Frost instead of the stored setpoints, provided the address operating mode is linked. The active operating mode also appears at the top left of the tile.

Tip: Heating and cooling are only shown when the valve outputs are linked. If there is only one common valve for both, link internal addresses for heat valve and cool valve instead.

Parameters

Display
Scene selection	Sets whether the element is offered for selection in the control element Block Scene Group.
View	Block or Basic Screen. The third choice List (deprecated) comes from older projects and should no longer be used.
Text	Caption of the tile. Its size scales with the element, a line break is inserted with \n, two lines at most.
Setpoint
Show setpoint	Shows the setpoint in the top row of the tile.
Step	Step of the + and – buttons in the dialog, default 0.5 °C. For a step larger than 0.1 °C the buttons snap to the next multiple.
Minimum / Maximum	Range of the setpoint, default 0 to 30. If both are equal, the setpoint is not limited.
Setpoint factor	Standalone only. The setpoint is sent multiplied by this factor and received values are divided by it – for devices that expect the temperature in tenths of a degree, for instance. Default 1.

Address links

With the variant presence all addresses sit at the function block. With the variant standalone the following are linked at the control element (those marked with * are required):

Operating mode*	1 = Comfort, 2 = Standby, 3 = Night, 4 = Frost. The setpoint that is set and shown depends on it.
Setpoint comfort*	Setpoint of the operating mode comfort.
Setpoint standby / night / frost	Optional. Setpoints of the other operating modes. If the device only has one setpoint, link the same address to all four. Not linked: 0 is shown in this operating mode and nothing is sent.
Actual room*	Measured room temperature.
Set point status	Optional. Feedback of the setpoint the device actually controls to – it can differ from the one set, for instance while the window is open. Not linked: the setpoint of the active operating mode is shown.
Heat valve / Cool valve	Optional. Control values; not equal to 0 shows flame or snowflake. Not linked: no heating/cooling symbol.
Valve heat/cool	Optional. Common control value when one valve is used for both. For showing heating and cooling see the tip above.
Fan coil feedback stage	Optional, in both variants. Running stage of the fan coil, 0 = off. Not linked: the fan symbol follows the selection made in the dialog.
