ETU-Simulation 5 EN

Version 5.5.1

With this version a new licensing was introduced, with the licensing via the Hottgneroth-ID you can register/deregister licenses independently from now on.

Version 5.4.2 from 04.09.2023 

This version includes the following bug fixes:

• The electricity consumer view is now also displayed with only PV quick examination, and all electricity consumers are also taken into account for self-consumption in quick examination.
• The amortisation diagram could be incorrect in the printout.

Version 5.4.1 from 26.07.2023 

In this version there are the following bug fixes:

• In the ETU Planner it could happen that some menu items were not visible.
• Occasionally it happened that no battery storage could be selected.

Version 5.4.0 from 10.07.2023 

In this version there are the following innovations

• The handling of the variants has been completely changed. It is now possible to switch between the variants directly via the title bar. 
• The PV connection search has been improved.

Version 5.3.2 from27.04.2023   

In this version there are the following bug fixes:

• In some constellations, the DIN calculation in PV had no result.

• The predefined demand profiles did not have a weekend.
• For locations outside Germany there was an error in the climate data of the summer heat protection
• New demand profiles could not be edited

Version 5.3.1 from 28.03.2023  

In this version there are the following innovations:

• The display of the parts lists has been revised and modernized. Now the parts lists can also be printed out again.
• The reference temperature for overtemperature hours can now be entered and is independent of the cooling setpoint.
• Dew point control of the cooling supply temperature in the simple system technology: In order to maximize the cooling capacity for a given cooling area, the supply temperature can now be lowered to a value just above the dew point temperature. This is only possible when cooling surfaces are selected.

Version 5.3.0 from 27.02.2023 

In this version there are the following innovations:

• Additional electricity consumers can now be entered, namely electric cars and charging stations. Thereby charging stations are rather intended for commercial uses and e-cars for residential buildings.
• In this context, the previous "Demand profiles" view has been replaced and the import and selection of predefined demand profiles has also been revised.
• In the Electricity Consumers view, consumptions can now be imported directly from csv files. This means that these are also displayed in the summary of electricity consumption on the right-hand side.
• The cxv import has been improved. The csv file to be imported is now validated directly and any problems are pointed out.
• The demand profiles can now be customized via the demand profile library.
• With many projects in the database there were delays in the program flow, this has been improved.
• For further compatibility with our programs, the underlying framework has been updated.

Version 5.2.3 from 13.01.2023

In this version there are the following bug fixes:

• In some constellations the PV quick view or the DIN calculation had no result.
• For Buildings entered via the table, module fields were sometimes not displayed in the PV simulation.
• After the plant simulation, an error occurred in some plant configurations

Version 5.2.2 from 21.12.2022 

This update contains the following innovations:

• To ensure future compatibility with the other programs from Hottgenroth Software, the underlying Framework has been updated
• If  there were a lot of contacts in the database, there were delays in the program flow, this has been improved.
• If a battery storage was selected, an error occurred in some circumstances during the printout, so that incorrect values for the self-consumption PV were output. This has been fixed.

Version 5.2.0 from 11.11.2022 

This update contains the following innovations:

• A catalog for electricity storages has been implemented, from which electricity storages can now be imported into the simulation.
• In the process, the interfaces for the electricity storages have been changed to a new design.

Version 5.1.2 from 08.08.2022 

This update contains the following innovations:

• The variant printout can now also be executed from an open variant. Previously, this was only possible from the root project.

Version 5.1.1 from 02.08.2022 

This update contains the following innovations:

• If individual project options cannot be selected due to licensing, this is now clearly displayed.
• The company address was occasionally not included in the printout. This has now been fixed.

Version 5.1.0 from 28.06.2022 

This update contains the following innovations:

• It is now possible to read in EPW files in the climate data view.
• In the variant comparison, the emissions of the variants are now also displayed and compared.
• A printout of the variant comparison is now also available. This can be called directly from the variant comparison.
• The startup process has been accelerated.
• In some constellations, the plants were not displayed correctly in the planner version. This has now been fixed.

Version 5.0.4.2 from 23.05.2022 

This update contains the following innovations:

• The Word-Export from the ETU-Planer is enabeld.
• The automatic interconnection of PV systems has been improved; it is now more robust.

Version 5.0.1.13 from 21.03.2022 

This update contains the following innovations:

• Licensing has been switched to our new license server.
• Variant comparison, which can be used to compare the results of different variants of a project.
• 

• Building capture directly in HottCAD, building data can be found by clicking the top left button in HottCAD.

• Climate data with new kilometer-resolved test reference years
• Fundamental change of the program substructure, incl. synchronization of project data with HottCAD
