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.

5 Commissioning
5.1 Mounting room transmitters
The device can be installed in dry surroundings (IP20) by screws on the wall surface or on the standard
flush mounting box. The recommended installation height is 150...180 cm.
The device position should be selected carefully. All the error factors that can affect to the
measurements should be eliminated as well as possible. The following list defines the typical
measurement error factors.
• direct sun light
• occupant proximity
• air flow coming from windows or doors
• air flow coming from ventilation nozzles
• air flow coming from the flush mounting box
• differential temperature caused by external wall
5.2 Wiring
WARNING: Device wiring and commissioning can only be carried out by qualified
professionals. Always make the device wirings in de-energised electricity network.
WARNING: External power sources and power wiring must be protected with a fuse or circuit
breaker. Rating depends on the overall system load, but the maximum rating for the external
circuit breaker is 16 A (limited by internal structure of the product).
WARNING: The minimum power rating for the external power source must be 170 VA / 170 W
to ensure proper operation of the internal fusing of the product in case of a failure condition.
Otherwise, the overall system power consumption shall be less than 15 W also in the failure
condition.
WARNING: This product is appliance class III product according to IEC 60664‑1. The product
may only be connected to SELV (separated extra low voltage) electricity network.
Important: This product has no capability to detect an abnormal condition of output ports.
External supervising (automated/human) may be needed depending on the application where
this product is used.
CAUTION: The product may only be connected to overvoltage category I, II or III electricity
network according to IEC 60664‑1.
