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 aeroVent recuperator using Modbus RTU communication protocol.
The documentation is available at: aeroVent - documentation.
This intergation allows us to read:
- device status;
- supply and exhaust fan speeds;
- operating mode;
- temperatures from available sensors;
- bypass and ground heat exchanger status;
and to control such parameters as:
- selection of operating mode;
- fan speed predefinitons for individual modes.
In order to execute this integration, there are needed:
- Gate Modbus (named Gate_Modbus)
- Recuperator aeroVent (Reversus, Flat)
Configuration of Modbus RTU virtual objects
- Create a ModbusRTU virtual object:
- The default communication parameters of the recuperator on the connector supporting the Modbus RTU protocol are 19200bd, 8 data bits, 2 stop bits, no parity.
For the default settings, enter the values of Embedded features in ModbusRTU virtual objects as follows:
* Device status (0 - device off, 1 - device on):
* Supply fan control level (in %):
* Exhaust fan control level (in %):
* Work mode (3 - gear 1, 4 - gear 2, 5 - gear 3):
* Supply temperature:
* Exhaust temperature:
*Bypass status (1 - open, 0 - closed):
* Ground heat exchanger status (1 - active, 0 - inactive):
* Ventilation mode (1 - active, 0 - inactive):
* Party mode (1 - active, 0 - inactive):
* Air supply fan speed - gear 1 (in %):
* Air exhaust fan speed - gear 1 (in %):
- Change to 10 the value of the ModbusMasterFrameSpace feature in the Gate Modbus module:
- Send the created configuration to the Gate Modbus module.
