I just replaced an RC80 with the Omnistat 2 and it will not commuicate with the touchscreen panel. The temperature just shows "0". I have addressed it in sequence with my other omnistat and set the baud rate at 100 w/ no luck. The only time it registers with the touchscreen is when I set the Omnistat 2 in the Zigbee mode. The Omnistat 2 will just sit there trying to link but does nothing. But while in the zigbee mode I can go down to the touchsreen and actually see the temperature reading. Once I get out of the Zigbee mode, the temperature reading at the touch panel shows "0".
