1 Introduction
RT transmitters are versatile room temperature and CO₂ transmitters for simple measuring
applications in building automation.
The transmitters can be equipped with following options:
• relative humidity measurement (-RH models)
• Modbus communication (-MOD models)
The -MOD models have Modbus RTU communication via the RS-485 connection.
Note: -MOD models don't include any other outputs.
The device commissioning is done by using MyProdual® smartphone application and MyTool® Connect
commissioning tool. Some of the basic settings can be also configured via bus in -MOD models.

4 Functional description
4.1 Multifunctional outputs
The device has three configurable outputs. The outputs can be configured for the following purposes:
• analogue measurement output (freely scalable inside 0...10 Vdc)
• two-state output (e.g. 0/10 Vdc)
• control the output via communication bus
You can use the two-state output for a simple thermostat type control by setting the wanted
measurement value contact settings and selecting the measurement contact to control the output.
Configuration can be done via communication bus or by using MyTool® Connect and MyProdual®.
4.2 Indicator lights
The -MOD models have an indicator light on the circuit board. The indicator light can be set for
following functions:
• off
• data transmit indication
• data receiving indication
• data transmit and receiving indication
CAUTION: When the power supply is connected, be extra careful when handling the product
without the cover.

6.2 Modbus function codes
The device supports the following Modbus function codes.
Decimal Hexa-
decimal
Function
3 0x03 Read Holding Registers
4 0x04 Read Input Registers
6 0x06 Write Single Register
16 0x10 Write Multiple Registers
23 0x17 Read/Write Multiple Registers
6.3 Modbus registers
The device uses the whole Modbus register space from 1 to 65535. Holding registers and input
registers are not tied to classic 4xxxx and 3xxxx areas. There are also many registers that has the
same register number but the function depends on the register type.
Important: Some BMS systems may need extra configuring to able to use the whole register
space. Contact the system vendor support if needed.
The registers are grouped according to the user guide. You can read or write only registers from one
group with the same Modbus command.
