The MER10 Smart Modbus Humidity and Temperature sensors have been designed for measuring room humidity and temperature in modern buildings. The MER10 Modbus sensors can have additional PIR occupancy sensor for movement indication and control. With LoraWan option the sensors can connect wirelessly to IoT or Building Management Systems.

The sensors have 2 x Universal Inputs (NTC10 resistance, 0-10V and digital), 4 x 0-10Vdc outputs and optional 24V relay output. The outputs can be used to send the measurement signals to BMS and other building controllers. The measurement signals can be scaled to match the controller input ranges. The inputs and outputs can also be controlled over the network, making the device operate as intelligent BACnet I/O-module.

With LCD colour display option the sensor can be used to indicated measurements and status of the control system. The measurement locations, descriptions, language etc. can be configured to suit the requirements. The sensor can also display parameters such as energy and water consumption readings.

The TS colour touchscreen option converts the smart sensor to operate also as the Room Interface Panel. The sensor can display measurements and energy readings, as well as it can be used to change the system setpoints, override the boost (timed) on/off, configure the fan speed levels and the operating modes. The display can be locked from unauthorized use. 

The smart sensors also incorporate 2 x PI control loops that can be used e.g. to control heating/cooling/humidity.

The LCD and TS skin colours can be changed to suit the building decor. In addition the smart sensors are available in black and white. The sensors are mounted on the wall surface directly or to standard wall mounting boxes. The sensors have built-in Modbus RS485 communication that allow interaction to the BMS systems (Building Management Systems). Optional Bluetooth wireless interface provides connection to Smart Phone App interface (iOS).

The MER10 Modbus sensors can be configured using Windows Device Configuration Tool (connected wirelessly using Bluetooth) or from SmartConfig iOS app. For ease of commissioning the sensor address can also be set from the bit switch or from the touchscreen.
