[Gate Modbus](https://knowledgebase.grenton.com/en/manuals?hsLang=en#gate-modbus) # Integration with the air conditioner using Intesis gateway The purpose of this article is presenting an integration of Grenton system with air conditioners via Intesis gateway using Modbus RTU communication protocol. Air conditioner chosen for this presentation is Fujitsu Air Conditioner ARYG09LLTA. The user manual of Intesis FJ-RC-MBS-1 (INMBSFGL001R000) gateway is available [here](https://knowledgebase.grenton.com/hubfs/user-manual-inmbsfgl001r000.pdf?hsLang=en). The integration allows to (for example): - read the state of device and turning it ON/OFF, - read the mode of work and change its state, - read the fan speed and change it, - read the value of set temperature and change its state. In order to execute this integration, there are needed: - Gate Modbus (named ***Gate\_Modbus***) - Air Conditioner, Fujitsu Air Conditioner ARYG09LLTA. **Note!** The Intesis gateway documentation states that wall-mounted control panels connected to the IntesisBox can work as a Master. This connection may block communication with the Gate Modbus module.   **Configuration of Modbus RTU virtual objects** 1\. Add ***Modbus\_RTU*** virtual object on *Gate\_Modbus*: ![](https://knowledgebase.grenton.com/hs-fs/hubfs/image-png-Jun-29-2026-08-12-33-2674-PM.png?width=336&height=274&name=image-png-Jun-29-2026-08-12-33-2674-PM.png) 2\. Enter the value of* Embedded features* in *Modbus\_RTU* virtual objects as follows: \* State: ![](https://knowledgebase.grenton.com/hs-fs/hubfs/image-png-Jun-29-2026-08-43-59-1235-PM.png?width=836&height=961&name=image-png-Jun-29-2026-08-43-59-1235-PM.png) **Note!** The device address and transmission speed set using DIP-Switch S3. The description how to proceed is placed in the user manual. The value of parity and stop bits are default and equal: none parity, 2 stop bits. \* Mode: ![](https://knowledgebase.grenton.com/hs-fs/hubfs/image-png-Jun-29-2026-08-44-36-3516-PM.png?width=836&height=961&name=image-png-Jun-29-2026-08-44-36-3516-PM.png) \* Fan speed: ![](https://knowledgebase.grenton.com/hs-fs/hubfs/image-png-Jun-29-2026-08-45-17-8779-PM.png?width=836&height=961&name=image-png-Jun-29-2026-08-45-17-8779-PM.png) \* Set temperature: ![](https://knowledgebase.grenton.com/hs-fs/hubfs/image-png-Jun-29-2026-08-46-22-2845-PM.png?width=836&height=961&name=image-png-Jun-29-2026-08-46-22-2845-PM.png) 3\. Upload the configuration to *Gate\_Modbus* module. - [Installation guidelines](https://knowledgebase.grenton.com/en/installation-guidelines?hsLang=en#main-content) - [How to Prepare Electrical Installation](https://knowledgebase.grenton.com/en/installation-guidelines?hsLang=en#how-to-prepare-electrical-installation) - [Reference devices](https://knowledgebase.grenton.com/en/reference-devices?hsLang=en#main-content) - [Integrated Device](https://knowledgebase.grenton.com/en/reference-devices?hsLang=en#integrated-device) - [Most Common Mistakes](https://knowledgebase.grenton.com/en/most-common-mistakes?hsLang=en) - [Electrical Installation](https://knowledgebase.grenton.com/en/electrical-installation?hsLang=en) - [Manuals](https://knowledgebase.grenton.com/en/manuals?hsLang=en#main-content) - [Gate Modbus](https://knowledgebase.grenton.com/en/manuals?hsLang=en#gate-modbus) - [Training](https://knowledgebase.grenton.com/en/manuals?hsLang=en#training) - [SW Applications](https://knowledgebase.grenton.com/en/manuals?hsLang=en#sw-applications) - [Gate HTTP](https://knowledgebase.grenton.com/en/manuals?hsLang=en#gate-http) - [Smart Panel](https://knowledgebase.grenton.com/en/manuals?hsLang=en#smart-panel) - [Configuration](https://knowledgebase.grenton.com/en/manuals?hsLang=en#configuration) - [myGrenton interfaces](https://knowledgebase.grenton.com/en/manuals?hsLang=en#mygrenton-interfaces) - [Virtual Objects](https://knowledgebase.grenton.com/en/manuals?hsLang=en#virtual-objects) - [Gate Alarm](https://knowledgebase.grenton.com/en/manuals?hsLang=en#gate-alarm) - [Intercom](https://knowledgebase.grenton.com/en/intercom?hsLang=en) - [FAQ](https://knowledgebase.grenton.com/en/faq?hsLang=en#main-content) - [FAQ](https://knowledgebase.grenton.com/en/faq?hsLang=en#faq) - [About Grenton](https://knowledgebase.grenton.com/en/faq?hsLang=en#about-grenton) - [Price list and documents](https://knowledgebase.grenton.com/en/price-list-and-documents?hsLang=en) [![Grenton logo](https://knowledgebase.grenton.com/hs-fs/hubfs/Logo_Grenton_variants_BIG_2020_plus_RGB_v0.2-02.png?width=400&height=100&name=Logo_Grenton_variants_BIG_2020_plus_RGB_v0.2-02.png "Grenton logo")](http://grenton.com) Copyright © 2026, Grenton Sp.z o.o.
