Product description
The RCTHH-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 controls a single analog/modulating output based on the measured values. This output can directly 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 has a 24 VDC power supply.
It provides flexible installation with spring-contact terminal blocks or an RJ45 connection. All parameters are accessible via Modbus RTU communication.
It features three 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

This sensor requires only little configuration. Once installed, it is almost ready to use. Temperature and relative humidity are frequently affected by region and season. These parameters are still set to the correct values during installation. The other default settings, on the other hand, will work with the majority of applications. They can still be changed if necessary by adjusting the corresponding Modbus registers. To make the sensor compatible with other devices, for example, a different output type can be selected: 0-10 VDC, 0-20 mA, 0-100% PWM, and Modbus RTU. The brightness of the LEDs used for status indication can also be adjusted. The Modbus register map provides an exhaustive list of all programmable settings.
What Are the Sensor's Manufacturing Quality, Calibration, and Protection Features?
This HVAC sensor controller was made in Europe. In our factory, each sensor is calibrated and tested. We use high-quality sensor elements and components. This ensures the HVAC controller's long-term stability and accuracy. The enclosure meets IP30 dust and moisture resistance standards and can be mounted on a wall or flat surface indoors. To ensure peak performance, keep it out of direct sunlight.
