Rated 3 out of 5 by from Outstanding controller, abysmal manual. This would be a 5+ star product if it weren't for the extraordinarily poor manual. This is a complex controller with a tremendous number of features and settings that can handle very difficult process control problems easily...once you figure out how to use it. Technical support, while very well meaning and committed to helping, was of not much assistance as they also relied on the same manual, and generally suggested "reading the manual" as a way out. I wouldn't have called if I hadn't read the manual. I will admit, that I am old, but I have been using Omega controllers for decades with few problems. The descriptions in the manual for this excellent controller were abysmal.

Rated 4 out of 5 by from Powerful, Compact, bit tricky to learn Works well, good features, bit tricky to program until reading on line manual. The included paper document is not clear about the button press timings to activate the three different menus.. Increasing and decreasing temperatures a bit slow as numbers increment and decrement slow as you hold the button. Bubble membrane buttons are not so easy to use they are so small, and require significant pressure to activate. You have to hold the little head unit I installed them in from moving as you press. Seems to hold temperatures very nicely, display is nice. Overall it is a very nice feature packed unit, and fairly easy to use once you figure it out.

Rated 5 out of 5 by from good quality temperature controller This instrument does exactly what I want and is very stable. It is easy to program as long as you follow the flow chart provided.

Rated 1 out of 5 by from DON'T The unit was so hard to program that even with Omega engineers helping/instructing me over the phone I could not get it to work. After 4 calls and about 8 hours on the phone I gave up.

Rated 5 out of 5 by from Great device for the cost Great little device for the money. I used it to heat a battery at a specific ramp rate until failure. Once it ran through its autotune, it held VERY accurately to that ramp rate. It takes a bit to learn all the functions, but once you know the features you need regularly it becomes straight forward. It has a lot more functionality than I think I'd ever need.

Rated 5 out of 5 by from Nice price to feature ratio. Easy to use, very good cost to feature ratio. Ramp functions are very useful, would have been nice to have finer resolution on ramp timing, but it works quite well.

do you have an example of setting up a pattern in the CND3 controller? I have set the pattern 0, turned on prog mode. Put system in RUN, it just heats and heats. Does the pattern wait to hit temperature before moving on

Asked by: Kirkllwork
Thank you for the inquiry. Please forward this in an email to TEMP@OMEGA.COM so that we can help you trouble shoot the problem. Note; Start you first target temperature to ambient room temp. Best regards OMEGA

Does this controller have a ramp to setpoint feature (or slope SV) that would work while a remote setpoint is used?

Asked by: Morgan
Thank you for your inquiry. This unit cannot use the SLOPE SV feature and REMOTE at the same time.

Does this Alarm stay latched and not be able to be reset if it is in an alarm condition. Example: Target heating SP of 800F and alarm high set at 1000F. If the PV is at 1050F, can you reset the alarm function? Same with a low temp alarm for cooling?

Asked by: ronb
Thank you for your inquiry. Alarms can be reset by activating the F1/F2 Buttons as reset.

I have a CN08D3-L-AC controller. The manual describes a "remote mode" that would allow the setting value to be controlled with a 0-10V analog signal. Can I add this feature by adding a remote board to the controller? If so, what is the part number?

Asked by: bmendelson
Thank you for your inquiry. The unit can accept the signal directly. No extra hardware needed.

What is the depth CN16D3-R-AC? I am able to find the panel cut out but am unable to find the depth the unit will stick into the cabinet.

Asked by: Zach1234
Thank you for your inquiry, the depth of the CN16D3-R-AC is 105.7 mm or 4.18 inches.

Is it correct that CN16D3-L-AC has one alarm relay with contacts rated for 3A?

Asked by: sketel
Hi Sketel, The CND3 series include 2 alarm outputs rated 3 amps resistive load. The L designation is for a voltage output for control. Best regards OMEGA

I have an AC device (CN16D3-LR-2U-CM-AC) rated at 100-240 V. How do I go about powering it? My device didn't include a power supply, but I noticed the rating matches the average outlet voltage, can it be powered directly without a transformer?

Asked by: ChemResearcher
Thank you for your inquiry. This controller is designed to be panel mounted and hard wired to the rear screw terminals with standard AC power (100 - 240 VAC). A power supply or transformer is not required.
