Are there any advantages to using this for Kessil lights vs the actual controller Kessil makes?
There is not a major advantage to using the VDM instead of the controller. The Controller is nice as it is easy to set up and control. The VDM will require some programming to get the kessil to run for specific times. Feel free to let us know if you have any further questions!
You will need one module for the Gyre (depending on if you want reverse the unit will take up v1/v2 and v3/v4. One Voltage port for the wave line (either V1/V2 or V3/V4) the sols require the serial port. If your sols are unable to be daisy chained (I do not believe they can) an individual VDM will be needed for each. Feel free to let us know if you have any further questions!
It depends on how you want to control the lights. If you want every light fixture to be able to be controlled individually, then you would need a VDM port for each individual light. Otherwise you use a single VDM port to control the first light and then daisy chain the other lights to the first light. The first light will be controlled by the controller and act as the master light and control all the daisy chained lights.
The module only works with the Tunze pumps (as far as controllable pumps goes that is). The Koralia doesn't have any 3rd party controllers that I am aware of and the line has also been discontinued.

Useful if you need more than the 4 built-in Apex variable outlets By Randall on 8/10/2017Randall would recommend this product to a friendI needed two variable ports for a Gyre pump I added to my system (one for variable speed, the other for forward/reverse direction), and only had one port left open on my Apex controller unit. This module is easy to set up and adds 4 (2+2) additional variable voltage ports, which function just like the built-in ones, to your Apex system.
Ok By Jason on 1/16/2017Jason would recommend this product to a friendLinks lights with the apex system. The only way to control my AI sols is with a controller, therefore required for my system. Works daily with no issues.
Very useful module By Damon on 6/20/2016Damon would recommend this product to a friendI currently use two of these modules with my Apex Jr. One to control circulation pumps (only 1 port used so far) and the other to control my Onyx dimmable light fixtures. It was quite easy to create profiles and outlets. Easy to modify as well. These are very helpful to make your reef a more natural ecosystem. Definitely recommend to other reefers... or even FOWLR keepers!
Works great for my LED's! By namoman28G on 4/16/2015namoman28G would recommend this product to a friendI installed an LED retro kit for my NC 28G and the VDM module worked great to mimic sunrise and sunset! I also use it for moon light phase. Very easy to install and program.
Works Nicely By JimVision on 11/10/2014JimVision would recommend this product to a friendHooks up to the Apex with no trouble. Finally I have light control.
Finally I can dim By Johnny Sea on 10/25/2014Johnny Sea would recommend this product to a friendI could not wait to dim my Kessil A360WE. BRS was excellent when the wrong module was shipped to me twice. It was easy to connect and program. Hardest thing is choose how ramp the color and the intensity.
Awesome By r1rider on 2/14/2014r1rider would recommend this product to a friendReceived it on time no damage work great all round awsom
Not Bad By john on 1/2/2014john would recommend this product to a friendIf you need to control led's or pumps with 1-10v with the apex, this is what you need. It installs easily. Like others have said the apex programming is not the easiest, but there are plenty of examples online.
Overall a good product.
It Works By Brad Patterson on 11/28/2013Brad Patterson would recommend this product to a friendIt does what it suppose too, once you figure out all the programming. I have the VDM for my Kessil A360W. Once I got all the profiles setup and all different control features working. No problems. Easy to install.
It's ok By Bob barker on 11/23/2013Bob barker would recommend this product to a friendIt works we'll but it's kind of a pain to get the hang of the programming. They really could have simplified it. Also they should have used a different typ of connection when not using the leds that they are mainly made to be used with. How ever when all is done it dose the job as advertised.
