Note! The following instruction is dedicated for the second generation of Modbus Gate module (FW: 1.1.10-2140)!


The purpose of this article is presenting an integration of Grenton system with Wanas recuperator using Modbus RTU communication protocol. 


The user manual is available at: Wanas - documentation


The integration allows to read the value of (for example):

  • air supply gear;
  • air exhaust gear;
  • air supply temperature;
  • air exhaust temperature.


In order to execute this integration, there are needed:

  • Gate Modbus (named Gate_Modbus)
  • Recuperator Wanas (e.g. Wanas 555 V_XF)



Configuration of Modbus virtual objects


1. Add Modbus virtual object on Gate_Modbus:



2. For default settings of recuperator - enter the values of Embedded features in Modbus virtual objects as follows:

* Air supply gear:



* Air exhaust gear:



* Air supply temperature:



* Air exhaust temperature:



* Gear of zone 1 (also Write function is available):




3. Send the configuration to the Gate Modbus.
