What do I do if the display on my Bliss Wifi Thermostat goes off?
Low battery levels may cause the BAT message to appear every 60 seconds. When batteries are completely discharged, OFF and BAT will flash together indicating device is offline until new batteries installed and settings reset as necessary(Pages 4-5)
