The minimum speed controller is a temperature-dependent ventilation controller for ventilated rooms with one or more exhaust air fans.
The ventilation controller keeps the room temperature constant and prevents the fan from running at a speed lower than the set number. It is easy to use, the desired temperature and the minimum speed is set by means of two knobs.
The fan controller is a stand-alone unit and is immediately ready for use. The set includes a waterproof housing, plugs with a flap and a digital voltage sensor, thanks to which the device is perfect for wet rooms.
The sensor is supplied with a 4 m cable which can be extended up to 50 m if necessary.
Housing: 130 x 80 x 70 mm
Fan controller: 145 x 100 x 90 mm
Dedicated for: 1 x 200W / TRIAC 1 x 16A
Voltage: 230V / 50Hz
Digital sensor: 5V, measures temperatures from -55 ° C to +125 ° C or from -67 ° F to +257 ° F.
Accuracy 0.5 ° C in the range from -10 ° C to +85 ° C
Protection class: IP44
The controller is a digital, temperature-dependent fan speed controller for air intake and exhaust radial fans.
It works by changing the fan efficiency when the temperature exceeds the designated point by 2 ° C. When the temperature is too high, the controller will accelerate the rotation of the fan blades, when the temperature stabilizes at the desired level, the fan returns to the previously set speed. The sensor included in the set has a 4 m long cable, if it is insufficient, it can be extended up to 50 m, with special attention when disassembling the old cable and installing a new one, as well as during the first start-up, because incorrect installation may damage the device's components.
Remember not to place the sensor too close to heat or light sources, because this may affect measurement errors and incorrect set parameters.
