Product description
The RCTHM-2 is a smart room sensor with adjustable temperature and relative humidity ranges.
It measures temperature (0-50 °C) and relative humidity (0-95% rH, non-condensing). It generates an output value based on the measured data, which can control an EC fan, AC fan speed controller, or a damper with an actuator.
It offers adjustable temperature and humidity ranges, and includes an ambient light sensor with adjustable 'active' and 'standby' levels.
It is powered by 24 VDC via Power over Modbus (PoM) with an RJ45 connector. All parameters are accessible via Modbus RTU. Firmware can be updated via Modbus RTU using its bootloader feature.
It features 3 LEDs with adjustable light intensity for status indication. It has an IP30 protection standard.
This sensor offers a smart and integrated solution to optimize your indoor climate control.

Additional specifications and description
It only takes one RJ45 connector to connect this sensor. Power over Modbus (PoM) refers to the connection of Modbus RTU communication and a 24 V DC power supply via one single cable. We recommend using a Sentera 24 V DC power supply with RJ45 connector to make wiring easier. These power supplies have short-circuit, overload, and overvoltage protection. A supply voltage of 24 V DC improves the safety and dependability of your installation.
