mike111 Posted August 8, 2014 Share Posted August 8, 2014 I have two sets of lights ("A" and "B" which I would like to control from two different locations in the condo. In each location there should be for each set an on/off switch + a dimmer: Since there are two sets of controls per set of lights, how do I select which set of switches is the "master", that is, determines the actual light strength? If I'm sitting at Location 1 I want the controls there ( switch + dimmer ) to be the master. Likewise when I'm at location 2. I tried explaining what I want to a Thai electrician but he kept saying this isnt viable. Would appreciate suggestions. Cheers Link to comment Share on other sites More sharing options...
bino Posted August 8, 2014 Share Posted August 8, 2014 I'm not a sparky - I am sure someone will come along with better information, but I believe your Thai electrician is right. This would be difficult to achieve with conventional "three way" wiring.Perhaps you would need to look at a home automation system like "X-10" modules and controllers.

firefox999uk Posted August 8, 2014 Share Posted August 8, 2014 I’m sure this would be better in the electrical forum. And I’m sure if it is possible 'Crossy' will have the answer. Have a Nice Day. Link to comment Share on other sites More sharing options...
ksamuiguy Posted August 8, 2014 Share Posted August 8, 2014 Remote switches are avaliable here in Thailand. with dilling capability, yes easy to install. They have them with 2 remotes if you want. if the lights are already installed Hard wiring difficult at best. remote control switches are the way to go.

Crossy Posted August 8, 2014 Share Posted August 8, 2014 Let's put this in electrical. As you need to operate the dimmer from both ends you need a remote dimming system, the dimmer itself sits somewhere convenient. This is controlled by as many remote switches as you want or even a keyfob remote control. Something like this http://www.tlc-direct.co.uk/Main_Index/Wiring_Accessories_Menu_Index/Wiring_Accessories~Dimmers_All/VL_IQ_Touch_Dimmers/Wiring_Accessories~Dimmers_5/index.html Try the dedicated lighting stores, they're certain to have something suitable (famous last words there).

trogers Posted August 9, 2014 Share Posted August 9, 2014 (edited) One dimmer to a set of lights with 2 switches. Dimmers need not be adjusted often. Thus you have a pair of wires between dimmer and light set, and a pair of wires between each switch and the dimmer.

mike111 Posted August 9, 2014 Author Share Posted August 9, 2014 Mates, tnx for the replies. Does this mean I need to carry around the remote control unit? This kind of negates the purpose of multiple switches. Isnt it possible to have wall mounted units at each location? Also with the remote unit, do I need one remote per dimmer (say one for lights A and another for lights B)? Cheers Link to comment Share on other sites More sharing options...

Wire the whole house up with microchips and you need only give verbal commands. Just fly in a couple of techies from the US. Link to comment Share on other sites More sharing options...
ksamuiguy Posted August 9, 2014 Share Posted August 9, 2014 Most remote switches come in 2 and 4 circuit so 1 remote controlls all. If you have a 2 way switch at each location you can add a dimmer next to the switch. if the wiring is not wired for a 2 way switch it would be a bitch as another wire would need to be added between switches. The make a dimmer with "Scene Control" but agian if not set up for 2 way a bitch. Link to comment Share on other sites More sharing options...
ksamuiguy Posted August 9, 2014 Share Posted August 9, 2014 You can also control your dimmers, gate, security devices from a Smart Phone also. Link to comment Share on other sites More sharing options...
Crossy Posted August 9, 2014 Share Posted August 9, 2014 If you don't want the handheld remote, you can use wall mount remotes like the ones in my link. 1 Link to comment Share on other sites More sharing options...
mike111 Posted August 9, 2014 Author Share Posted August 9, 2014 Tnx, but again which dimmer will actuallt determine the lights state? Say the master dimmer unit is on setting 1 while I'm using a slave dimmer unit and setting it to setting 2. Which setting prevails? Link to comment Share on other sites More sharing options...
RichCor Posted August 9, 2014 Share Posted August 9, 2014 There are two or more methods to wire this. One would be to use a WIRED Switched circuit. The first example (Fig 8.) is for ON/OFF Switch only, and relies on (2) 3-Way and (1 or more) 4-Way 'Switches' to control the on/off state of a light or lights. The second example (Fig 9.) is similar but uses (1) ON/OFF-'master' Dimmer control and (2 or more) SLAVE-Dimmer controls to control the on/dimmer/off state of a light or string of lights. The SLAVE-Dimmer sends 'signals' to the 'master' Dimmer to adjust the on/dimmer/off state. This requires 3-WAY WIRING [ (2) Hot-capable Load Wires and (1) Neutral ] be run between each Switch Box. _________ A second method would be use battery-operated Radio Controlled Light/Dimmer remote controls. These can either look like "remote controls" OR look like Light Switches with Dimmer Controls that get mounted to the wall where a normal switch might go. It then is used to 'send' signals to a 'master' control to change the on/dimmer/off state of a light or string of lights. The Radio in each remote is used to send signals to the 'master' receiver/controller so no extra/special wiring would be required. As already stated, some can even be controlled over WiFi with a SmartPhone App ( google "Whole House Controls" There are a number of ways that these things can work. Just google "Radio-Controlled Remote Wall Dimmer Switch" and select IMAGES for examples. Examples, like this Luminode or this Olutron image show Fully Wired or Battery Powered Remote Plates: Link to comment Share on other sites More sharing options...
mike111 Posted August 9, 2014 Author Share Posted August 9, 2014 Tnx RichCor, this clarifies quite a bit the master/slave setup. Are the wireless master/slave dimmer wall-mounted units available in Thailand? Cheers Link to comment Share on other sites More sharing options...
mike111 Posted August 10, 2014 Author Share Posted August 10, 2014 Bump Any shops in pattaya/jomtien which carry these wireless wall mounted dimmers (master+slave)? Cheers Link to comment Share on other sites More sharing options...
RichCor Posted August 10, 2014 Share Posted August 10, 2014 (edited) You may want to look at places that sell ceiling fans, or lighting electrical shops. Sorry, I don't know the Chonburi area that well. //edit A google search turned up a page containing possible businesses from a Farang Friendly? website: Pornchai Electric 27/11 Moo5 Sawang Fa Road, Naklua, Bang Lamung, Pattaya, 20150 L E D Studio Moo 6, Sukhumvit Road, Pattaya, Bang Lamung, Central Pattaya, Pattaya, 20150 Porchai Lighting 10/3, Moo 6, Pattaya Nua (North Road), Pattaya, Bang Lamung, Central Pattaya, Pattaya, 20150 Sang Udom Lighting Moo 4, Sukhumvit Road, Pattaya, Bang Lamung, Central Pattaya, Pattaya, 20150 Gecko Light & Decor Moo 12, Sukhumvit Road, Pattaya, Bang Lamung, Central Pattaya, Pattaya, 20150 La Movida - Jomtien Moo 12 Soi 5, Beach Road, Jomtien, Bang Lamung, Jomtien, Pattaya, 20150 Edited August 10, 2014 by RichCor Link to comment Share on other sites More sharing options...
mike111 Posted August 10, 2014 Author Share Posted August 10, 2014 Tnx. I have enquired in one of the big home depot-style mega shops here but the staff said they've never heard of wireless dimmers. Cheers Link to comment Share on other sites More sharing options...
RichCor Posted August 10, 2014 Share Posted August 10, 2014 While most 'wired' dimmers need to be 'gang wired' (attached together in a string), they also make remote units that attach to any electrical wiring as these second type work by sending signals over the in-home wiring and work fine so long as there aren't electrical-noise-inducing appliances on the same circuit. Just ask people what type of multiple-location light dimmer units they sell. Hopefully you'll be shown something that acts as a master with multiple remote slave in the Wired 3-way, Wired X10, Wired Automated Home, Wired with Radio Control, or Battery Powered Wireless Control units. I wonder where Crossy went? He probably knows where these things are sold locally. You might want to try to PM him with a question. Link to comment Share on other sites More sharing options...
