4. Connection to a Modbus network
The following data is available for write access:
Description
Set temperature from BMS
Set speed, supply air fan from BMS
Set speed, extract air fan from BMS
Set value, fresh air proportion
from BMS
Set pressure, supply air from BMS
Set pressure, extract air from BMS
Set flow rate, supply air from BMS
Set flow rate, extract air from BMS
Set value, fan mode
(stage or ON/OFF) from BMS
Set value, relative humidity from BMS
Set value, absolute humidity
from BMS
Offset set temperature
Offset set speed, supply air fan
Offset set speed, extract air fan
Offset set value, fresh air proportion
Offset set pressure, supply air
Offset set pressure, extract air
Offset set value, relative humidity
Offset set value, absolute humidity
Offset set flow rate, supply air
Offset set flow rate, extract air
Operating mode
Outside temperature from BMS
Values with a factor = 0.1 are transferred with a decimal place. The required
value equals the specified value times 0.1.
Example: Required value for set temperature = 24.3 °C -> value to be
specified = 243.
For values with a factor = 1, the value to be specified equals the required
value (no decimal place).
Example: Required value for set fresh air proportion = 45 % -> value to be
specified = 45.
For values with a factor = 10, the required value equals the value to be
specified multiplied by 10.
Example:
Required value for set flow rate, supply air = 1300 m³/h -> value to be specified
= 130.
Note:
Subject to the implementation of the MODBUS connection, it may
be necessary to add the value of 1 to the index.
