Integration with PRO-VENT recuperator

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

The documentation is available at: PRO-VENT - documentation.

This intergation allows us to read:

• ventilation operating mode;
• ventilation speed;
• heater operating mode;
• heater setpoint temperature;
• outside air temperature;
• exhaust air temperature;
• ventilation efficiency (supply / exhaust);

and to control such parameters as:

• ventilation operating mode;
• ventilation speed;
• heater operating mode;
• heater setpoint temperature.

In order to execute this integration, there are needed:

• Gate Modbus (named Gate_Modbus)
• Recuperator PRO-VENT

Configuration of Modbus RTU virtual objects

1. Create a ModbusRTU virtual object:
   
   
   
   
2. Ensure that the following transmission parameters are set in the integrated recuperator: 19200 bd, 8 data bits, 1 stop bit, with parity (Even).
   
   For these settings, enter the values ​​of Embedded features in ModbusRTU virtual objects as follows:
   
   * Ventilation mode (0 - manual, 1 - auto):
   
   
   * Ventilation speed:
   
   
   * Heater opertaing mode (0 - off,1 - manual, 2 - auto):
   
   
   * Heater setpoint temperature:
   
   
   * Outside air temperature :
   
   
   * Exhaust air temperature:
   
   
   * Ventilation efficiency - supply :
   
   
   * Ventilation efficiency - exhaust:
   
   
   
   
3. Change to 10 the value of the ModbusMasterFrameSpace feature in the Gate Modbus module:
   
   
   
   
4. Send the created configuration to the Gate Modbus module.
