GSE, dual-fan and negative-pressure controller

A controller with temperature, minimum speed, and negative pressure settings for controlling intake and exhaust fans.

Dimensions and technical data:

• Product dimensions: W80xH80xD130mm
• Package dimensions: W150xH110xD170mm
• Designed for: 2A / 2x200W / TRIAC 2x16A
• Voltage: 230V / 50HZ
• The 5V digital sensor measures temperatures from –55°C to +125°C (–67°F to +257°F )
• 0.5°C Accuracy from –10°C to +85°C
• Protection rating: IP54 

Setting range:

• Temperature: from 20C° to 30C°
• Minimum speed: off, 20%, 100%
• Negative pressure: 100% to 50%

Instructions for use here!

• The controller operates one or two fans: one for intake and one for exhaust, or two for exhaust. Connect the exhaust fan to "Fan 1" and the intake fan to "Fan 2". Set the desired temperature.
• The "Minimum Speed" setting sets the exhaust fan's minimum speed as a percentage of its maximum speed. Set it to "Off" to stop ventilation when it isn't needed; any other setting will keep it running at the selected speed.
• The "Negative Pressure" setting sets the intake fan speed as a percentage of the exhaust fan speed. If you use this controller for 2 exhaust fans, set it to 100%; otherwise, determine a suitable value by experimentation.
• As the temperature rises, the fan speeds gradually increase, reaching 100% when the temperature rises by 2°. As the temperature drops, the speeds decrease again to the level set under "Minimum Speed".
• Maintains a constant temperature, while negative pressure contains odors.
• Can be used for two exhaust fans, provided there is free airflow into the room.
• Ready to use, reliable, with a waterproof housing, socket covers, and a low-voltage sensor, making it ideal for humid environments.
• The sensor has a 4m cable that can be extended up to 50m.

Negative pressure is adjusted by balancing the intake and exhaust fans. The TRIAC 2 × 16 A rating describes the components and does not mean a permitted load of 16 A on each fan output.

Choosing a climate controller

Match the load type and control method. An AC fan with adjustable voltage and an EC fan with a signal input require different control. Follow the limits for the specific model.
