How Does the LTY Series Offer User-Friendly and Efficient Fan Control for Homes?
Residential environments usually require a simple control solution that is also cost effective. Moreover, at home the looks always matter! The design of the LTY series is plain and fits any interior style. Controlling the fan speed using this controller is as easy as turning on and off the lights at home. Via its only button – a rotary knob - the fan speed is set from minimum to maximum by simply turning it clockwise. The device a solid and reliable control solution which reduces the noise levels emitted by the fan and increases the service life of the motor connected to it thanks to the TRIAC technique used.
Reduced fan speed uses significantly less power than maximum operation and can often be employed, typically during unoccupied or low occupancy. What you get is simplified manual control, reliability and efficiency.
How Does TRIAC Technology Work to Control AC Motor Speed?
TRIAC - contraction of Triode for Alternating Current - is a three terminal electronic component that conducts current in either direction when triggered. In general, the TRIAC device is a semiconductor that can be used for AC systems as a switch. The technique used is called phase-angle control and employs the ability of the power semiconductor to switch on current when its gate is energised and to automatically switch off again when the current flowing through it falls to zero.
How Can the "OFF" Position Be Managed for Continuous Fan Operation?
The LTY features an OFF position - turning the knob anticlockwise stops the motor. If necessary, the OFF position can be deactivated. In this case, the motor can keep on working when the power supply is available, i.e. when the device is connected to the mains, even though the device has not been manually activated by turning the knob. As standard, the supply voltage to the LTY is connected via terminals ↑ and N. If you would like to disable the OFF position, you need to connect the supply voltage via the terminals intended for the unregulated output, namely ↓ and N.
What Is the Purpose and Function of the Unregulated Output?
The LTY features an unregulated output which is active when the motor is enabled. If the supply voltage is connected to ↑ and N, the unregulated output is active while the motor is in operation. The unregulated output is used to control external devices such as dampers, relays, run indicators, etc. that can work without the need to regulate the incoming voltage. So the controller regulates the fan through the so called “regulated output” via controlling the voltage with the option to regulate one more device. But this time the voltage is “unregulated”, i.e. either 0 V or 230 V.
If you connect the supply voltage to the LTY as standard and as advised by the relevant documentation, the unregulated output of your controller will be active when the motor is enabled. This means that when the fan stops, the connected external device will be disabled – the damper will be closed or the run indicator will switch off. While the fan is working, the damper will remain open and the indication light will be switched on. The maximum current is 2 A.
How Is Minimum Fan Speed Optimized for Performance and Noise Reduction?
The LTY features an internal trimmer for adjusting the minimum fan speed. The motor might produce a little more noise at lower speeds. The minimum motor voltage can be adjusted in order to avoid motor stalling at low via the minimum speed trimmer. It can be set within the range 20% - 70% of the supply voltage.
What Is the Purpose of the Integrated LED Indicator?
The orange LED indicates the operation status. During normal motor operation, the orange LED is solid on.
What Motor Types Are Compatible and Can Multiple Motors Be Connected?
The series is intended for AC fans and control is realised via reducing the motor voltage. AC fans run on an alternating current and convert alternating current into mechanical power. This means that the series is suitable only for voltage controllable motors. You can connect several motors to the controller as long as the current limit is not exceeded. If you are not sure about your motor type, we strongly advise you to read carefully its accompanying documentation or contact the motor manufacturer.
What Are the Design, Durability, and Mounting Features of the Enclosure?
The enclosure of the LTY is made of high-quality ASA plastic in cream colour (RAL9010). The material is UV resistant and protects the electronics against dust, water and impacts. Basically, you can install the LTY in any kind of wall - it is fit for both flush and surface mounting. If you choose the flush mounting option, it fits perfectly the standard European box. The protection class is IP44 for flush and IP54 for surface mounting. Furthermore, it looks really nice and combines with any interior style. Cleaning it is very easy using only a damp cloth.
