Quick Start Information for Temperature Controllers
Good news! We’ve recently posted Quick Start, Autotuning, and Sample Programming guides for the Eurotherm 3504 temperature controller in our Tutorials section. The 3504 is most often the controller supplied with our furnace control systems unless you request a different model.
Setup guides are also posted for the West N6701 and the Future Design Controls L-91 overtemperature protection controllers.
Note that for the Eurotherm 3504, there are a variety of guides for controllers with no events, multiple events, and different thermocouple types. The guides for the West N6701 are available for different thermocouple types. There is only a single guide for the Future Design Controls L-91; it covers all thermocouple types.
While every controller is supplied with the manufacturer’s operating manual, using our guides to learn how to execute basic setup and operating procedures can save you a great deal of time and frustration.


Quick Start information is included in every Deltech furnace manual when the system is shipped, but manuals have a way of getting damaged or disappearing over time. Contact us if you need a replacement manual(s) for your Deltech furnace, even if your system is very old. Email sales@deltechfurnaces.com for assistance. Also email us if you don’t find the Quick Start guide that applies your particular system. Our team will be glad to promptly send you the correct version.
While you are on our Tutorials page, check out some of the articles and videos you will find there. They provide guidance on furnace selection, furnace troubleshooting, and element installation and replacement, to name a few of the topics covered there.
As always, if don’t find the information you need, contact us via email, phone, or use our contact form
