HI,

Just wondered if anyone has used Marmitek's x10 Micromodules that are made to fit behind existing wallswitches and walloutlets?

I'm using the AW12, in double throw switch mode. Works fine

Hi,

Do you control it with the TM13 Tranceiver?

Was is easy to install and program the unit?

So then you only control one light with one of the switches with the AW12 correct?

I am mostly interested in if someone has used the LWM1 module with built in dimmer. It's supposed to work with low voltage halogen lamps.

I have not used it with TM13 yet, (I've just got one). I use it with the mini-timer to control the entrance hall lights. I also have it linked to the original hard-wired two-way switches, so I can control it from both ends of the entrace hall - it's totally transparent in that mode.

It was very easy to install and program using the mini-timer.

Here's the manual

Hi,

I wonder if it is possible to program the module with the Pronto and the TM13?

-Hinke

Providing you can send the required codes - you may need to set the TM13 to the house code you want to use for the AW12 if you don't have the AH version.

I found the easiest way to to program it (AW12)was before installation - I set it up on the bench with a hardwired switch, as using the switch is the easiest way to put it into program mode. Then just send the relevant command as per the manual via the TM13.

eg, set non-AH TM13 to house code "B". Press the switch linked to the AW12 five times in close succession. Send "4 on" twice via the TM13. Then either wait 60 seconds or press the switch 5 times. The AW12 is now on address B4.

For AH TM13, I'd guess you could either set the code as above, or set it to AH mode and use the pronto to send both house and unit code. But I've not tried it.

Similar sequence for setting up response to "all" commands.

I take it you guys are in Europe. Wish we had the DIN and micro modules in 110/220. (or am I missing something?)

Yes, I'm in the UK. Didn't realise these were Europe (ie 230v/50Hz) only - pity, they are very useful.

But then again, you have all these lovely scene capable dimmers - PCS etc and we only have the LD11 DIN module, which is not really useful in a retrofit (Lighting wiring in the UK loops the mains feeds between ceiling points, with 2-wire drops to the switches)

I have built alot of hardwire lighting control enclosures using solid state "puck" relays and DIN mount PLC's (thats programmable logic controller, not power line carrier). The thought of a 110 volt DIN mount X10 relay makes me salivate! And those miniature switches are way cool also. Inspectors here would frown at the low volt flying leads however...........

Another question about micromodules from Marmitek:

They only work on one phase, unless you have filter for lots of money that can reproduce the x10 signal on all 3 phases.

I have 3 phases in my house since the stove/oven is on all 3. It is then split up into groups on the 3 different phases. The kitchen is on one phase, the livingroom is on another phase.

My question is this: Wouldn't it be possible to have one TM13 for each phase? The TM13 listens on 433MHz, so I could possibly have one TM13 for each phase in the house controling the Micromodules on each phase.

Do you guys understand what I mean?

Thanks.

Hi again.

I must have missunderstood the specs of these products. It is the Micromodules transmitter that can't transmit on all 3 phases. So, I should be able to have any Micromodule anywhere in the house and it should work with the TM13, even if they are on different phases. The problem occurs if I want one Micromodule to talk to another Micromodule that are on different phases.

Correct?

-Hinke

"I have 3 phases in my house since the stove/oven is on all 3."

Do you really have a 3 phase stove? or are you referring to the split phase + neutral + ground that most are wired with?

It's a 3 phase stove (380volts). In Sweden this is very common, in fact I think only apartments might have 230v 1 phase stoves. The effect is better. That's why we increased from 220v to 230v some years ago to get better usage out of the electricity.

We have 3 phases coming into the house. The stove is on all 3 phases. Then the house is split into groups that are evenly divided between the phases.

For example:

Group 1: Stove
Group 2: Stove
Group 3: Stove
Group 4: Livingroom
Group 5: Laundry room
Group 6: North bedroom
Group 7: South Bedroom
...
...

This means:
Group 1, 3, 6... is on the same phase.
Group 2, 5, 8... is on the same phase.
Group 3, 6, 9... is on the same phase.

If the Micromodules can't transmit over all phases, can the TM13 Transciever do it?

The TM13 should transmit on the pahse it is plugged into. Whether or not the signal reaches other phsses depends on your elecrival system over there.

If it does not, then you should, as you suggest, be able to plug a TM13 into each phase set to the same house code. Then each TM13 will receive the RF signal from the remote and sent the X10 signal onto the mains, and all should be well

Hi,

Yes, I have figured that out now. You have to use 3 TM13's if you want them on all phases. Or you can get a filter that will transmit the signal on all phases, but that requires hiring an electrician.
