GSE EC LCD Controller for 2 Fans – Climate Controller for two EC Fans
Ventilation controller
The GSE EC LCD Controller for 2 Fans enables precise and convenient control of two EC fans for intake and exhaust air. A total of 15 different settings can be programmed via the clear LCD display and three control buttons. This allows temperature, humidity, and fan performance to be automatically adjusted to the desired climate conditions.
The included sensor monitors temperature, humidity, and light. The integrated light sensor automatically detects the transition between day and night. Separate setpoints for temperature, humidity, and minimum and maximum fan speed can be defined for both operating phases. Additionally, the performance of the intake fan relative to the exhaust fan can be adjusted using the negative pressure setting.
The LCD display continuously shows the most important values, including the current temperature, humidity, and fan speed in RPM. Further setpoints and settings can be accessed and changed via the control buttons.
The GSE Controller is supplied ready for use. The scope of delivery includes a temperature, humidity, and light sensor with a 4-meter cable, two 4-meter fan cables, a power supply unit, and an RJ45 adapter plug. The controller is exclusively intended for use with compatible EC fans.
