In the spotlight
HVAC transmitter to measure temperature, relative humidity, CO2 (carbon dioxide) and ambient light level. The supply voltage is 24 VDC. The green, yellow and red LED indicators provide a visual indication of the CO2 level. The measured values are transmitted via three analogue outputs and via Modbus RTU communication. The default output type is 0-10 V. Different output types can be selected. The CO2 sensor element is replaceable. In many applications, the ambient light detection is used to control the ventilation system in function of the occupancy of the room. All settings can be adjusted via Modbus RTU communication. Also the light intensity of the LEDs for status indication is adjustable. Typically, this CO2 sensor is used in schools, office buildings, restaurants, etc. to monitor the carbon dioxide level and to check if sufficient fresh air is supplied into the room.

Variable speed controller for AC fans with single-phase motor. The combined maximum motor current is 1,5 A. All settings - including the operating mode - are adjustable via Modbus RTU communication. This controller can regulate AC fan speed from high to low speed or from low to high speed. The motor accelerates with softstart or with kickstart. One hardware, different functionalities. The enclosure allows inset mounting or surface mounting. The supply voltage is 230 VAC. Phase angle control (Triac technology) is used to vary the motor voltage and to regulate the motor speed. This variable speed controller is often used to control ceiling fans, bathroom exhaust fans, extraction fans etc.

24 Volt switching power supply for loads up to 40 Watt. The enclosure offers IP65 protection against ingress of water and dirt. This makes it possible to install this power supply in harsh environments. The input voltage is 85—264 VAC. The overload and overvoltage protection increase the safety of your electrical installation. The load can be connected via the spring cage terminal block or via the RJ45 connector.

CO2 sensor to measure temperature, relative humidity, CO2 (carbon dioxide) and ambient light level. The unique enclosure allows flush mounting or surface mounting. The supply voltage is 230 VAC. The sensor algorithm controls one 0-10 V output based on the measured values. This single output directly controls an EC fan, an AC fan speed controller or a damper actuator. All measurements and the output value are available via Modbus RTU communication. The CO2 sensor element is replaceable. In many applications, the ambient light detection is used to control the ventilation system in function of the occupancy of the room.

Potentiometer with 0-10 V output and Modbus RTU communication. The supply voltage is 85-264 VAC. The dry contact output can be used for remote ON-OFF control of an EC fan. The analogue output signal can be set via the rotary knob with off-position. Via Modbus RTU, following output types can be selected: 0-10 VDC / 0-20 mA / 0-100 % PWM. This potentiometer controls EC fans, AC fan speed controllers or damper actuators. The output range is adjustable via Modbus RTU. The minimum output value can be adjusted between 0 to 40 %. The maximum output value can be adjusted between 60 to 100 %. The splash-proof enclosure allows inset mounting (IP44) or surface mounting (IP54).

This transformer fan speed controllers regulates fan speed manually or demand based. It controls single-phase motors. The (combined) maximum motor current is 1,5 A. RTVS1 is controlled via Modbus communication. A Sentera HVAC sensor, potentiometer (SPV series) or a BMS system can be used to adjust the requested fan speed. Fan speed is regulated by varying the motor voltage in steps. The autotransformer technology generates a motor voltage with a perfect sinusoidal shape. This guarantees quiet motor operation. A special impregnated coating reduces the electrical noise from the autotransformers. The enclosure allows surface mounting (IP54 protection). Fan speed can be controlled manually or based on temperature, relative humidity, CO2, air quality (TVOC) or CO. The supply voltage is 230 VAC.
