FWIW, I set mine either 17/18 or 18/19 (not at the laser, so I can't confirm). Maybe it is a bit of overkill but the chiller has no problem keeping it in that range and I want one less variable affecting my cutting power.
Thank you for your reply.
The questions is that as far as I can see, I can't set my chiller lower than 20 on the "allowed highest water temperature" (I will ask S&A if that is normal...)

Depending on the controller programming you might find there is two upper set points. Fairly normal is you have a set point of say 15C and a Hysteresis (allowed variation) of 1-2C and then an alarm setting of 20C as an example. That is the Chiller will try and maintain 15+-1-2C and will alarm at 20C.
The other option is there will be three set points, a lower one, an upper one and an alarm one. I haven't run across this with the cheaper chinese temperature controllers but it is fairly normal on industrial ones.
I don't have a manual for the module but from the basic manual I downloaded a week ago for my CAD project it talks about E2 as an over temperature alarm so there must be a set point for it.

Don't ask how, but for some reason I was not sawing the most obvious parameter, the " Temperature Setting".
So, I have adjust the chiller for:
- Temperature Setting: 19C
- The allowed highest water temperature: 20
- The allowed lowest water temperatute: 18
- Alarm for ultrahigh water temperature: 23
Do you believe that this is a good setting, or shoul I set an even smaller range?
Accessories: Ruida RDC6442G EC controller, 2" lens, S&A CW5000 chiller, chuck type of rotary attachment, Russ' DoHickey (sp?), mA meter, a growing collection of tools and oddities to keep it running!
Since I have an extra temperature sensor, what you think about using it to check the temperature on the tube, putting the sensor right on the tube with some tape?
I am also thinking on put an analog amp meter to check the tube current, since I dont have none info from the manufactor, is there any other way to know whats the amp limit for my tube?
Accessories: I have a combining lenses, pin tables [homebuilt], honeycomb tables , wireless remote, Modifed Ultimate Air Assist, home built non-powered rotary device, PrusaMK4 and Mini Prusa printers.
I think you are overthinking it . The analog mA meter is a very good thing tho. There are charts that give the approx max current depending upon the length of the tube. Does your tube have a brand associated with it?

Getting any sort of accurate reading from the Glass Surface is a bad choice because of the material. You really need to have the sensor in the flow of water. Generally some sort of T Piece with the sensor in one of the ports.
As I have been drawing up the Laser system I have been having a thing about Flowmeters and Temperature sensors for the cooling loop.
What they also sell is just the sensor end https://www.ebay.com.au/itm/G1-2-Brass- ... 3471674405 and is of more interest to me to tinker with. As a project run an Arduino Nano and a simple two line display and some simple code to just display current Temp and Flow.
