VDL 4-in-1 Climatron Pro Sensor – Replacement Temperature, Humidity, CO₂ and Light Sensor

VDL 4-in-1 Climatron Pro Sensor – Replacement Temperature, Humidity, CO₂ and Light Sensor

The VDL Sensor 4 in 1 model BLS-4 is the environmental sensor for the VDL Climatron Pro controller: it measures air temperature, humidity, CO₂ and light in a single body, and sends those readings to the controller so it can manage the room's climate control. This sensor is already included as standard with the Climatron Pro, so you do not need to buy it to get the equipment up and running. This part number is the replacement unit and also the way to add a second sensor to monitor another area of the grow room.

Key features

• Four measurements in a single sensor: air temperature, humidity, CO₂ and light, without the need to install four separate probes.
• BLS-4 model: it is the original sensor for the Climatron Pro system, not a generic substitute.
• Powered by the controller: it runs on the 12 V output voltage of the Climatron Pro itself, without an additional power supply.
• Replacement or second unit: useful for both replacing the original sensor and covering a second area within the same installation.
• Grow room operating range: operational from 0 to 50 °C and up to 90% relative humidity.

Compatibility

This sensor is designed for the VDL Climatron Pro controller (ref. 600492), to which it connects via the RJ12 6P6C RS485 sensor port. Keep in mind that the Climatron Pro already includes it as standard: it is not an accessory required to start using the controller. Only buy it if you need to replace the original sensor or if you want to add a second unit to monitor another area of the grow room. The controller supports a maximum of 3 sensors in total, across all types.

At GrowIndustry we only work with proven quality products and trusted brands.

Every item goes through a check before shipping to make sure it arrives in perfect condition and ready to use.

Your satisfaction is our priority.

1. Disconnect the VDL Climatron Pro from the power supply before handling the sensor.
2. If you are replacing the original sensor, remove its connector from the controller's RJ12 sensor port.
3. Connect the 4-in-1 sensor cable to the Climatron Pro's 6P6C RJ12 port; if you add a second unit, use the splitter to share the port.
4. Place the sensor at the height of the plant canopy, avoiding the direct output of the extractor fan, humidifier, and light fixture.
5. Reconnect the controller to the power supply and check the screen to ensure that temperature, humidity, CO2, and light readings are being received.
6. If you add more sensors, remember that the Climatron Pro supports a maximum of 3 in total and manually calibrate the CO2 from the controller menu.
