Ceiling Fan

[raymonvdm]

Some time ago i bought a "Gamma Ceiling Fan" but after the warranty expired the thing broke down The fan is working but in the middle of the night it will switch on its light which is quite annoying.

There are now a few paths to choose.

1) Replace the fan with a new one (Co-Worker had serveral of them all of them broke down)
2) Replace the control unit of the fan (Only for sale in batches of 1000 pieces) although i just found this link which looks to be the same
3) Fix it using another control method

Let`s choose option 3 for the sake of this forum


This is the fan we are talking about and i hope this forum is the correct one



And this is the remote (Model No AA1)





And the control unit inside the fan (HJ-1020-IR AA2009-9)




I`m looking for a way to control the motor of the fan. It currently has 3 fan speeds but only the first one has ever been used. The speed is managed by the control unit which is a little bit broken. The light is dimmable using the control unit but only on/off is used so i can use an on/off wall switch for it

Anyone ?

Have you already opened the control unit inside the fan? I think the capacitors are worn out. Often very cheap capacitors are used in products like this, and because the unit is connected to power 24/7, they will wear out faster.

Could be as easy as a 5 euro fix Bad capacitors can be recognized because their topcover is bulging, or brown goo is leaking out of it. See Google 'bad capacitor' for more images.

Otherwise you could build something like this: http://domoticz.com/forum/viewtopic.php ... t=20#p1118 (uses ACM-3500 from KaKu to have 3 different speed options).
Or just go the cheap route and put in a single contact module (like ACM-1000 or Z-Wave equivalent), i am planning something similar.

Can the remote be picked up by RFXCOM?

[raymonvdm]

I cannot use a ACM-3500 because the fan is only equipped with two wires and i think the speed is regulated using PWM. It is not possible to use a single Z-Wave switch because it will run on full speed and you will be blown out of your bed

The remote is infrared so it cannot be picked up using RFXcom and i have bought a infrared kit for it which i never used yet

Maybe use a arduino , that can control PWM, use a transistor or something to you can switch higher voltage and Amps ?
just an idea.
It can be made wireless with a bit of effort if you really want.

Last week we removed the dust from the ceiling fan to start it up again. (It`s working most of the time) and thought of this topic again. I also noticed the fan has a rating of 55 Watt but did not build an Domotica Solution yet
