Help needed with automation of a ceiling fan

[mosseltje]

Hey Everybody,

I looking to include a few ceiling fans in my home automation.

I bought one that I like because it comes with a winter/summer switch.

For those who don't know:

The summer / winter switch changes the direction of the motor.

During the summer you want the fan to blow down, creating a downward wind that has a cooling effect on the body.

During the winter you change the direction of the motor so it basically pushes the hot air pocket that is against the ceiling downward and heat a room more efficient ( +10% according to google results)

Photo 1 shows you the model,

Photo 2 shows you the components

Photo 3 shows you the schematics and the loxone set-up according to me.

The top part is the actual schematic:

L goes to a rotary switch (3 low-med and high speed via 2 condensators packed in one )

The summer/winter switch basically reverses L and N on 2 of the 4 motor connections

The lower part of the schematics does the same but via Loxone.

The way I see it I'll need 7 !!! outputs of 1 fan . That's very expensive if I want more fans in my house.

So does anybody have any better idea's or solutions that wont cost me an extension per fan ? ? ( at max speed the motor takes 65W of power)

thanks in advance.

a single 2 pole 2 way relay operated by a single loxone relay will take care of the forward/reverse.

if you can afford 2 more relay outputs per fan then thats 3 relay outputs in total per fan.

if you dont need the extensions for anything else, there are cheaper options for output relays:

1) kx digital outputs (you just need a knx power supply as well)

2) dmx extension and dmx relays

3) network relays controlled with virtual ouputs eg

I recently posted a DIY project here. Uses standard 3-wire A/C wiring and speed controlled by a 0-10V input (which can be generated by a cheap DMX to 0-10V converter).

I've automated two ceiling fans at our house, in both cases I removed the rotary switch and ran the wires to miniserver extension relays (three used).  We decided not to automate the reversing switch as it is only use twice a year (once in the fall and once in the spring) and our fans are easily reachable so no problem doing it manually.  The first fan we ordered with a light in it, but after using it we decided we really didn't like having a light in the fan so the second one we ordered with no light.

The second fan, a Westinghouse "Cyclone" model, caused a bit of head scratching as the the rotary switch was not simply a 1 pole, 3 position for the three speeds, it did different combinations (something like; position 1 = 1+3 connected, position 2 = 1+2 connected, position 3 = 1+2+3 connected).  Once I looked up the switch and found this info,  I did the logic in Loxone.  Something to check.

BTW, we would give high marks to this fan; excellent build quality, motor completely silent, no vibration, low power consumption, looks great. 

The hardest part was fitting the additional wires down through the shaft to be able to hook them up to the switch outputs.  I used .75mm insulated solid core wire which worked fine.

Thanks for the Tip Duncan,

The DPDT relay would cut the 7 outputs to 4:

1) Q1 on my schematic --> speed 1

2) Q2 on my schematic --> speed 2

3) Q3-Q4-Q5-Q6 --> new Q3 --> summer/winter switch

4) Q7 on my schematic to complete the circuit.

I have never used or explored any of the options that you've suggested so I'll have some learning to do.

I think the DMX option seems the best for me since it could also be used for lights, dimming and leds. Do I need to do some specific programming (which I can't) to use DMX or does it all work with the standard blocks from Loxone?

Thanks Jedi,  But your solution is a bit too DIY for my liking. The Idea of using 0-10V to make it switch between the speeds is brilliant? ( since I'm only using 1 AQ at the moment an have 5 extensions running)

is there a possibility that this functionality exists in a standardised commercial relay ?

Hey Russ,

Mine ( Westinghouse) has the same combination rotary switch as you described  but as we could possibly go to 4 or 5 fans we'll be ending with a lot of outputs :)

However there is some wisdom in the idea of not automating the summer/winter switch...

I wish there was. I could only find them on high-end systems like Crestron.
