Introduction Product overview Iddero Verso is an advanced room controller with a , " capacitive touch display designed for visualisation and control of KNX installations. It is available in white or black finish, and can be installed in portrait or landscape mode.
7. Multifunction inputs connector 8. Replaceable RTC backup battery In order to bring up the device, connect the KNX bus to the KNX TP connector ( ), and a separate power supply ( - VDC) to the power supply connector ( ). Please refer to the product datasheet for detailed information on the power supply requirements.
The Synchronization page will remain onscreen as long as the device has not yet been pro- grammed with application data from ETS. This page is also displayed if the KNX bus is discon- nected, or while the device is being reprogrammed.
2.1.1 Overview The Iddero Verso user interface is organized into pages. This includes both configurable function pages (also called “control pages”) and fixed function pages, such as the Menu or settings pages. The following diagram provides a high level view of the navigation structure:...
Page 9
The following screenshots show the main elements of the user interface in both portrait and landscape modes: The status bar ( ) at the top of the screen shows the name of the current page, and, optionally, the current time and temperature. The main area of the screen ( ) shows the icons, buttons, and user interface elements relative to the current menu or function page.
2.1.2 Home page Upon startup, the Home page is shown automatically. The Home page can be configured to show the current date and time, and also the current temperature. Tapping anywhere on the screen will automatically switch to the “default page”. The “default page” can be the Menu page, the Favorites page, or any of the configured control pages.
2.1.3 Menu page The Menu page provides quick and easy access to all pages in the visualisation, including: • Any of the configured control pages (up to ) • The time schedules pages • The alarms pages • The Favorites page •...
2.1.4 Control pages Control pages contain up to configurable widgets, known as “components”. Available compo- nent types include the following: • Indicators • Indicators with alarm function • Push buttons • Double push buttons • Regulation bars • Rotary controls •...
2.1.5 Favorites page In addition to the regular control pages, a “favorites” page allows end users to select up to eight commonly used components for quick access. Any of the configured components can be selected; see . . . Edit favorites page on page .

Any user configuration will be discarded, including preferences, timer schedules, scene values, etc. The device will be le in the same state as if it had been just programmed from ETS. Note: The following settings are not a ected by this option: –...
2.1.7 Page layout Many of the pages in the user interface are arranged as a grid that can contain up to elements. The position of each element in the grid is shown in the following figure: For certain pages, including the Menu page, the configurable control pages, and the Favorites page, several layout options are available.

2.1.8 Access control Most pages in the user interface can be password protected with a -digit PIN code in order to prevent unauthorized access. Two access control schemes can be configured: Either one single password is used for all password-protected pages (one access level), or two di erent access levels are defined (“user” and “master”).
2.1.10 Touch gestures Iddero Verso supports the use of touch gestures for quickly executing up to five preconfigured actions. Touch gestures can be used while the device is in power saving mode, and also in the Home screen. The following gestures are detected: •...
A di erent action can be configured for each gesture. When the touch gesture is detected, the associated action will be executed and the device will play a short confirmation sound. Typical uses for touch gestures include switching on the lights on a dark room (the multitouch gesture makes this specially easy, as users just need to place their hand on top of the screen), or activating a “Welcome”...
Each component enabled as a timer can be optionally added to one of four available “timer groups”. Timer groups can be locked (temporarily disabled) by sending a KNX telegram to a specific communication object. While a timer group is locked, any scheduled actions for components associated to that timer group will not run.
Page 23
Selecting one component from the list shows the available programs: Time schedules...
Page 24
The “Enable” checkbox allows to manually enable or disable any configured actions. Note that this checkbox will be disabled if the component belongs to a timer group that is currently locked. Selecting a program shows the program edit page, where all the parameters for the timer program can be edited.
Page 25
For this, the component provides two additional communication objects: A “trigger” object, and an “acknowledge” object. When the “trigger” communication object receives an alarm value from the bus (the “alarm condition”), the alarm is activated. This is signalled both visually, in the user interface, and via the built-in buzzer device.
2.3.2 Alarm visualisation All configured alarms, along with their current state, can be checked at any time from the “Alarms” page, which is reached from the Menu page. Alarm state is shown as follows: Symbols State ALARM state WAIT_ACK state (waiting for acknowledgement) WAIT_OFF state (waiting for deactivation of the alarm condition) OFF (idle) state From this page it is also possible to acknowledge individual alarms (by selecting each one and...
2.3.3 Alarm log An internal alarm log holds information about the latest alarm events, including the event date and time. The alarm log can be reached from the alarms page (“Alarm log”) button. The following events are logged: Symbol Meaning The alarm is triggered The alarm is acknowledged, but the alarm condition persists (the “no alarm”...
2.4.1 Overview Iddero Verso implements two independent thermostats for ambient temperature regulation, and thus can be used to control two independent HVAC zones. Each thermostat can be config- ured for heating, cooling, or both heating and cooling. The thermostat continuously compares the current room temperature with the current temperature setpoint, and controls operation of the heating and/or cooling actuators using a variety of control methods.
Page 29
• Economy mode: If the room will not be used for a longer period of time (for example during the night) the temperature setpoint can be relaxed even further in order to achieve higher energy savings. • Building protection mode: In this mode, the room thermostat is out of service. The room will only be heated (or cooled) if the room temperature has reached values so low (or high) that there is a risk of the installation being damaged from freezing or overheating.
Page 30
Example Let’s assume the following configuration: • Thermostat is configured for cooling operation • Comfort setpoint is set to ºC • Standby setpoint is set to ºC If the thermostat is in initially in Comfort mode, and a value of ºC is written to the “Setpoint”...
Page 31
The base setpoint can be modified at any time through the “Base setpoint” communication object. The mode o set for each mode is configured via ETS parameters, and cannot be changed at runtime. The user o set allows additional adjustment of the current setpoint within a configurable range.
Note Writing to the -byte mode object will always set the operating mode regardless of the value of the -bit objects, and vice-versa. When a new operating mode is selected, the current temperature setpoint will be set to that of the new operating mode.
Page 33
• If the thermostat is in cooling mode, it will automatically switch to Heating if the room temperature falls below the corresponding setpoint for Heating mode. • If the thermostat is in heating mode, it will automatically switch to Cooling if the room temperature rises above the corresponding setpoint for Cooling mode.
2.4.5 Control algorithms The main function of the Iddero Verso thermostats is to compare the current room temperature with the desired temperature (setpoint) and send appropriate commands to the KNX actuators (relay outputs, valve motors, etc.) that control the actual HVAC equipment.
Page 35
In Heating mode: • The output is switched on when the room temperature is less than or equal to Setpoint - lower hysteresis • The output is switched o when the room temperature is greater than or equal to Setpoint + upper hysteresis Lower Upper...
Page 36
Two-point control with hysteresis is easy to setup and can be used with regular switching actuators. However, it is also sub-optimal in terms of power consumption and comfort, due to the typical fluctuations of the room temperature around the setpoint which arise as a result of the simple control algorithm.
Page 37
current temperature and the desired setpoint) reaches ºC. If the di erence is only ºC ( % of the proportional band), the output will be set to %, and so on. • Integral time: The P-I control algorithm not only considers the current value of the error term at any given time, but also the “history”...
Page 38
2.4.5.3 P-I Control with PWM Output In the P-I Control algorithm described in the previous section (P-I Control with Continuous Output) the control variable that is periodically sent to the HVAC actuator is an analogue variable %). Thus, a proportional HVAC actuator is required. In some cases, however, it is desirable to benefit from the advantages of P-I control, while still being able to use standard (lower cost) switching actuators, such as relays and actuators for zone valves.
The Iddero Verso thermostats can be configured to control these auxiliary heating or cooling systems, if they are installed. For this, it is necessary to define a temperature range where the auxiliary system will kick in.
For a detailed description of the available configuration options for each type of input, see Inputs on page 2.5.1 Binary inputs 2.5.1.1 Push button inputs Push button inputs are typically connected to external push buttons, and can be configured to trigger di erent actions upon detection of “short” and “long” presses. For example, a push button input can be connected to a physical push button to control a light dimmer.
2.6.1 Internal vs. External scenes Many of the functions in Iddero Verso (such as touch gestures, or components used in the visualisation) can be configured to trigger so called “external” scenes. External scenes are managed by external KNX devices, which are in charge of storing the scene values, and recalling them when the scene is triggered.
Scenes can be recalled and stored in a variety of ways: • When the user activates a scene push button or double push button component in the visualisation • Through the “Run/save internal scene” communication object • As a response to certain actions, such as touch gestures 2.6.3 Recalling scenes When the internal scene controller receives a request to recall a given scene, all scene actuators...

This operation will ultimately open or close the shutter completely, unless it is interrupted. Shutter actuators with absolute positioning A long press on any of the buttons will bring up a window with a regulation bar.
Page 77
RGBW Controls are specialized components that can be used to control both RGB and RGBW (RGB + White) LED dimmer actuators. The RGB object type parameter sets whether the RGBW control should use three separate -byte R, G, B communication objects (one per channel), or one combined -byte RGB object. The Use white channel parameter selects whether a white channel should also be controlled, in addition to the Red, Green, and Blue channels.
Page 78
While the color selection window is open: • Use the “view switch” button ( ) to toggle between the “color wheel” and “color bars” views. This is only available if white channel control is not enabled; if the component is configured to control a white channel, the color bars view is always used.

Page 80
The le and right buttons allow selection of an absolute temperature value that will be sent to the bus. It is possible to configure the minimum and maximum temperature values that can be selected, as well as the increment or decrement that is applied on a short or long press of the buttons.
Page 81
When new values are received from the bus through the Temperature indicator object, the internal temperature o set value remains unchanged, and the internal base temperature value is updated so that the resulting absolute temperature matches the received value. Additionally, a Temperature o set status object is available in order to externally update the internal temperature o set value.
