Guardian® pig heaters also include a unique, built-in Advanced Service Saver™ diagnostic feature that simplifies troubleshooting and helps keep your heater running when you need it the most. The ignition control module in Guardian® heaters is self-diagnostic. If a problem exists, a red LED light on the module will flash a specific pattern depending upon the problem that is diagnosed. If the light flashes, the flash pattern will be followed by a pause and then a repeat of the flash pattern until the problem is corrected. Flash patterns are provided in the heater service guide.
L.B. White Guardian® heaters that help pork producers control pig house climates are available in CSA U.S. and Canada certified models, as well as other international configurations and certifications.
