Troubleshooting, ACTIVE ALARMS screen | Enviro EA800 manual

Troubleshooting

Operating or setup errors are indicated by flashing data on the display. Often, a programming error also results in an alarm for the misprogrammed relay. The table below shows and describes common error displays, along with corrective action. For updated information, go to the EA800 page at www.winland.com and look for the troubleshooting section.
