Noob Question

Hi, Im new to C-BUS. Can someone roughly explain about ULTI switch (MKII-no fuse). I would like to know how to setup ULTI.




Question 1.
What does the program button and reset for? Is there any manual how to use that program button?

Q2.What is L and Load for? Does L stand for Life? Load for? My Life,Neutral,and Earth should connect to which one? and my lighting -Life and Neutral connect to which one? Please assist me in this. I will much appreciated if someone can explain / Answer my questions. Thank You.

 

This forum is for C-Bus products, and ULTI products do not use C-Bus, so you'll find help a bit thin on the ground here. ULTI products use a 1-way RF technology called EZInstall and it is not related to C-Bus or C-Bus Wireless in any way.

Nevertheless, here we go...

Each ULTI unit comes with an instruction manual that explains how to program it. It should be in the box with the product.

The program and clear buttons are used during the initial set-up of the unit. The program button allows you to connect this dimmer/switch to a remote control. The Clear button allows you to delete programming information from the unit.

"L" is for Line. This is the in-coming mains supply.

"Load" is for the controlled load on the unit, usually a light of some sort.

Most ULTI products are 2-wire devices. That means that they do not require a Neutral connection. They get their power from a small amount of power trickling through the Load, even when the light is off. There are exceptions, so you'll need to look at each individual product to confirm the wiring requirements. They are intended to be a direct replacement for regular light switches.

 

Hi, Newman, Thank You so much for the useful info..im very appreciate it. As you said, this forum only for C-BUS porducts.. Is there any forum for EZinstall ? From what i understand, the picture below is what i understand. Is this correct? please correct me if im wrong. Thank You.

 

That picture is correct in concept, except that it should be Line, not Life. As I said earlier, you'll need to check the wiring information that is supplied with each product to confirm the correct wiring requirements. The wiring rules also vary from country to country, so you'll need to check with your local wiring rules.

There is no equivalent forum for EZInstall. You'll need to contact Clipsal sales in your country for more support.

 

Hi Newman,

Could I take you to task on this?

Take a look at http://www.clipsal-ulti.com/pdf/integrated automation 1.pdf where they state quite clearly that Ulti uses RF technology to communicate with other C Bus devices.

Surely this means that Ulti is using C Bus, and that Ulti can talk to C Bus, and C Bus can talk to Ulti.

 

Sure, task away!

Let me clarify...

Traditionally ULTI referred to a specific range of 1-way RF retrofit products sold in Asia. The products had no brand information on them other than the words ULTI. The Clipsal C-Bus Saturn range of products and accessories are also promoted under the ULTI marketing name in Asia since the glass look is very similar to the original ULTI RF switches. Since then, a range of mechanical switches and hotel accessories have been developed in a look that fits the ULTI family of products as well, and hence also branded ULTI. Finally, just to confuse things, there was a time when C-Bus Wireless was advertised in Asia as ULTI, however all the product packaging and instructions all just said C-Bus Wireless.

The Clipsal ULTI website promotes all of these different products as "ULTI", as ULTI has progressed from being a specific subset of products to a term that refers to all products that look a particular way.

So, you've got me over a technicality, but it was pretty clear (to me) that Smartcbus was talking about the original RF retrofit switches that originated the ULTI name, utilising the EZInstall 1-way RF technology.

 

Hi newman, its me again, Im facing some technical problem which i have no idea why it act such. Ive make a testing of my own, follow the diagram that i posted here.... so.. when i switch on, theres no trip, i assume that the connection is correct. But when i come to on the switch, the bulb lights on for abt 3 sec and it turn off automatically...ive tested with other switches.. the same problem applied to other switches. So i would like to ask any expertise like you can figure out whats happening? Thank You.

 

First check the basics. Make sure your Line connection to the unit is protected by the circuit breaker, make sure the load connection on the unit goes to your lamp and that there is a neutral return after the lamp. Make sure that your lamp is of a sufficient size. An incandescent lamp of 40W - 100W is what you should be using for testing.

Try pressing and releasing the Program button and then press and hold the Clear button for approximately 5 seconds. This should reset the unit back to the defaults.

Failing that, I suggest you contact Clipsal technical support in your country.

 

Thank again Newman..i deeply appreciate for your help.. ive figure out my problems base on your useful information.. =) Thanks alot. Im done with EZinstall ( On / off Switch). Now about the dimmer, i face some problem with the dimmer... i try to use 60W lamp (dim able). When i on the switch (MCB) the light that control by dimmer keep flushing but somoehow it wouldnt flash when it is in use and still can dimm to 1% til 100%. and when i off the dimmer, it ( button LED and lighting )keep flashing again. Any idea what happen? Thank You.

 

When you say that you have a 60W dimmable lamp, exactly what type of lamp is this? If it is a compact fluorescent type then you may experience problems. Is it really 60W or is it equivalent to 60W?

I suggest that you test it with an Incandescent lamp of 40W - 100W first. If this works OK then you know that your 60W dimmable lamp is not compatible with the ULTI Dimmer.

 

Hi Newman.. my bad, i didnt mention what lamp i use.. im using Incandescent lamp with 40W. Ive tested with other watt usch as 60W and 100W.. all giving the same result... Flashing. How to trace whelther the dimm switch is defect or not? Is there any possibility the symptom shows that the dimm switch is defect?

 

If I understand you correctly, when you turn the lamp On it works fine, i.e. you can dim the lamp smoothly up and down. When you turn the lamp off, then the lamp flickers? This is the same for both 40W and 100W incandescent bulbs?

I would try re-setting the unit back to factory defaults, as I described in an earlier post.

If you get any flickering at all from the blue LEDs that back-light the buttons after this then it sounds like your unit may be faulty.
