FAQ's Z41 Lite

The application program available on the website is only valid for ETS4 or ETS5, is there a compatible version with ETS3?

No, the application program developed for the Z41 is only compatible with ETS4 or ETS5.

I cannot import the application program for the Z41, the ETS4 shows the message “The version of the Scheme is not valid", what can I do?

To import the application program for the Z41 is necessary to have the ETS4 software updated with a version of "Scheme" 1.1 or higher. You can view this information from the main screen of the ETS4, in the Overview section. The version information is displayed in the upper right corner.

May I install the Z41 horizontally?

Yes, from the Z41 Pro/Lite 2.3 versions and Z41 COM 1.1, this touch panels may be installed horizontally or vertically. On the other hand, InZennio Z41 can't be installed horizontally

May I use the KNX bus voltage (29VDC) as the additional power supply of the Z41?

No, the KNX bus voltage is not a clean signal as it is modulated by the data. This signal can cause a malfunction of the screen.

The KNX bus connector and the external power supply connector are opto-isolated to avoid potential interference with the KNX bus.

Do I need an additional KNX power supply as external power supply for the Z41?

No, the auxiliary power supply does not need to be a KNX power supply, a conventional power supply (12-29V DC), or the auxiliary output of some KNX power supplies is enough.

What is the total consumption of the Z41?

The consumption of the Z41 is divided as follows:

• KNX Bus: 6 mA
• External power supply: the maximum consumption at startup is 160 mA (with 12 V), 76 mA (with 24 V) or 64 mA (with 29 V), but in standby, its consumption is reduced to about half of this figure.

It can be checked in the Z41 datasheet

What is the firmware of the Z41?, and how can I update it?

We call firmware to the base software preloaded on the device that handles the display of all items on the screen. The firmware is independent of the ETS application program, but both must be the same version for the Z41 to work properly.

The firmware update must be performed via the miniUSB port or the Ethernet port:

• Via USB: using the adapter cable for USB firmware update connected to the mini-USB port placed on the back of the touch screen. The “.PAK” file for firmware update  must be copied to the root folder of a USB flash drive.

• Via Ethernet: Downloading de Z41 Update tool and connecting the touch panel to be updated and the computer to the same local network. Z41 Lite cannot be updated via Ethernet

Both procedures are explained step by step in the firmware update manual

Should I update first the firmware or the software?

Even though it can be done in both ways, from Zennio we recommend to update firstly the firmware version, and secondly the application program.

The screen stays with blue background and it displays an “Error Software” message. What is going on?

The “Error Software” message means a wrong correspondence between Software and Firmware versions. 

Software version X.Y must match with the firmware version X.Y.Z. The versions will be compatible when X.Y values are equal.

What is the Ethernet input for?

The Ethernet port built into the Z41 may be used to upgrade its firmware, and for the remote controlling of the Z41 via IP from devices such as smartphones or tablets.

How can I know the Z41 MAC number?

The MAC is displayed on the screen when the touch panel is in the firmware update state.

It is also possible to know it by running the command “arp-a” in the command shell (cmd) of a computer connected to the same network.

If a power failure occurs, do I need to re-set the date and time?

No, thanks to the button battery included in the Z41, the touch panel allows to keep the date and time data after a power failure.

When are the date and time of the Z41 sent to the BUS?

The Z41 Touch Panel only sends the date and time data to the BUS when these two options are set, more specifically when the SET button is pressed, at the end of the manual parameterization.
This feature allows synchronizing the date and time of the rest of Panels in the installation by creating two group addresses “Date” and “Time” to later link them with the appropriate communication objects in the rest of panels to synchronize; this way when adjusting date and time in one of the "master" panels, the rest of them will be also updated.

When having several touch screens Z41 Pro, InZennio Z41 and Z41 Lite in the same installation, How is recommended to configure the time/date sending period?

It is recommended to configure just one screen in the installation to send time and date periodically to the bus, disabling in the remaining devices the parameter “Time/Date Sending Period” that can be found at MAIN CONFIGURATION/ General.

What alphabets can be displayed on the Z41?

Z41 is able to show the following alphabets:

• Latin
• Greek
• Cyrillic
• Arabian
• Hebrew
• Chinese
• Japanese

Is it possible to disable the temperature, date and time displayed at the top of the screen?

Starting from the InZennio Z41 version 2.0, Z41 Pro 1.1 and Z41 Lite 1.1, it is possible to disable the display of this information through the GENERAL setting parameters independently.

Can I show a temperature value different from the one measured by the internal sensor in the header of the screen?

This is possible starting from the InZennio Z41 version 2.0, Z41 Pro 1.1 and Z41 Lite 1.1, by enabling this option in the GENERAL setting parameters.

How can I display the values ​​received in an indicator control over time?

Starting from the version InZennio Z41 v2.0, Z41 Pro 1.1 y Z41 Lite 1.1, it is possible to save a log of the values ​​received in indicator controls of 1 or 2 bytes simply by enabling this option via the "Save Log?" parameter. Then, pressing on the indicator will open a pop-up window that will display graphically the values received in this indicator over time.

I have configured an “Energy Monitor” control to display the energy consumption and the objects that I need to link with my energy monitor do not appear. I can only see the objects “Energy Monitor: request” and “Energy Monitor: reset”, why?

To use this “Energy Monitor” control, it is necessary to enable the monitoring channels via the “Energy Monitor Objects” tab that you will find in the MAIN CONFIGURATION section. For each channel, four objects will be created: “Power”, “Energy”, “CO2” and “Cost Estimation”.

I have configured a 2-button control and the value sent by each button does not correspond to its icon. What’s happening?

When configuring the 2-button control, it must be taken into account that the icon selection parameter does not assign functionality to the button. The icon is independent of the value sent.

Starting from version InZennio Z41 v2.0, Z41 Pro 1.1 y Z41 Lite 1.1, all the 2-button controls will have a parameter called "Action" that will allow exchanging the value sent to the bus between the left and right buttons.

I have configured a RGBW control and the object corresponding to the white channel does not appear, I can only see the objects corresponding to the red, green and blue channels, why?

To use the white channel, it is necessary to enable it via the “White Channel Objects” tab that you will find in the MAIN CONFIGURATION section. For each channel, one object will be created: “[RGBW] White Channel”.

I have several scenes scheduled to be launched at the same time and only one is launched, why?

Due to the fact that the scene object is unique to the entire touch panel, it is only possible to launch one scene at a time, more precisely, the scene launched will be the one set in the last box of the last page. To avoid this effect, the sending of the scenes can be shifted in time.

How can I schedule a Heating System timer using special modes?

1. Enable Automatic ON when a new special mode arrives in Thermostat configuration and enable Trigger in parameter 1-bit objects working mode in Setpoint configuration.

2.  3 new Communication objects appear for each special mode activation. When sending "1" to any of these objects, the specific Setpoint Temperature is set while an ON order is also sent to the Heating system.

3. Enable four Schedule Programming controls: three controls to send "1" to the corresponding special mode and one more to send the scheduled OFF.

As an example, 4 Group Addresses will be necessary to use the 3 special modes with the Schedule Programming: 

• Comfort: with the Comfort object of the thermostat and the timer object of the corresponding control.
• Standby: with the Standby object of the thermostat and the timer object of the corresponding control.
• Economic: with the Economic object of the thermostat and the timer object of the corresponding control.
• OFF: with the ON/OFF object of the climate system and the timer object of the corresponding control.

What is the Technical Alarm Cyclical Monitoring used for?

This function allows a critical alarm system monitoring ( ie gas sensor) to check its proper working in the installation.

The function in this case, waits for a value reception to confirm that the system is working properly. If this value is not received within the specific time parameterized in the ETS, the alarm goes off warning users of a possible problem in the device.

The internal temperature sensor of the Z41 shows a higher temperature value than the real one, Why?

The InZennio Z41 usually gets hot during its programming in such a way that the real temperature is distorted during this time period. The InZennio Z41 will recover the real temperature once it returns to its standby status.

Furthermore, supplying the InZennio Z41 with a voltage value or another can cause variations in the measurement of the temperature; however, the temperature displayed is automatically calibrated by selecting the “Power Supply Voltage” parameter properly.

Additionally, the internal temperature sensor can be calibrated manually from the ETS setup or from the configuration page.

Can the temperature measured by the internal sensor of the InZennio Z41 be sent periodically to the bus?

Yes, within the parameters of the InZennio Z41, it is possible to choose a cyclic sending period of the temperature measured by the internal sensor with a range between 10 and 1000 s.

What is the welcome object for?

The welcome object can be used to send a binary value to the bus or to launch a scene, the first time that the touch panel is pressed after a configurable time of inactivity. This object can be very useful to turn a light on or to launch a welcome scene.

This control is only available starting from the InZennio Z41 version v2.0, Z41 Pro 1.1 y Z41 Lite 1.1

What is the locking for?

The lock object allows enabling or disabling the touch area of the Z41, so that if the screen is locked, it ignores any press on it until it is unlocked. This object may be useful to disable touch panels installed in public areas.
