Hi,
Is it possible to automate mechanical ventilation using a KAKU module?

Mechanical Ventilation - with Kaku?
Re: Mechanical Ventilation - with Kaku?
So which module do you use for that?
(looking at how it's done with a SAIX)

Re: Mechanical Ventilation - with Kaku?
Ah, you probaly mean with mechanical ventilation the whole house ventilation system that newly build highly isolated houses have.
I thought you meant a ventilation unit used for a bathroom only

Re: Mechanical Ventilation - with Kaku?
I`m using a Duwi Z-Wave Switch for this. (But i think KAKU will do fine)
Normale mode is 2 (by design)
Switch closed is Mode 3 (High Speed when taking shower)

Re: Mechanical Ventilation - with Kaku?
Hi DJ
I'm using KaKu and DomotiGa to control my Eco Fan.
In the kitchen there is a High/Low switch to set the speed manually. The two wires from this switch are extended in parrallel to a place where a standard KaKu unit is installed.
The KaKu unit controls a small relay connected to the two wires. The relay is installed in a standard gray installation box from Gamma. A 220v standard mains socket is installed in the cover; the KaKu unit is put into the socket. Of course you need to supply 220 volts for the mains socket to the gray box, otherwise the KaKu is not working.
Then at the location of the Eco fan, I installed another gray installion box (I bought 2 at Gamma ).
In this box is again a small relay installed that is controlled with the h/l switch or the KaKu (they are in parrallel remember). The relay contacts are controlling the speed of the Eco fan. The nc contact for low speed and the no contact for high speed.
The 2 relays are the same: 220V/5A from Conrad (http://www.conrad.nl/ce/nl/product/5033 ... archDetail).
You can buy a complete set with mounted relay on a pcb and a kind of universal mounting kit consisting of two sides that click together to form a housing. But warn you, Conrad site is a mess around this product. But its cheap
I'm a bit in two worlds now, since replacing the old AC fan with an Eco fan is now finished and under control of an Oregon humidity sensor and Domotiga. I'm prepairing to move towards the use of the Eco fan RF remote control and 3 relais, from wich the contacts are in parrallel to the switches of the remote control. All that should be controlled by the Velleman k8055 and a relais board attached. Its a bit expensive solution, but saw no other way arround it because of support by Domotiga was required. With this solution I can control 3 speeds, where the above described solution only controls 2. Have some relays left for other smart things
Check the DomotiGa site of Ron for more info in the Wiki under Weeder as an alternative 'controller'.

Re: Mechanical Ventilation - with Kaku?
which Kaku module do you use? The ACM-1000?
My SAIX12 is built into the ventilation unit. Don't think the ACM-1000 will fit

Re: Mechanical Ventilation - with Kaku?
Hi DJ, that is quite some time ago!
I used a KaKu with the formfactor of an ACM1000, but one of the cheaper series.
Because I did not build it into the eco fan size did not matter.
Inside the gray box is a 220 volt socket and squeezed the releais pcb to the side that holds the contacts in parallel to the fan switch in the kitchen.
