Hope someone can help me, we powered down the denco systems over the weekend but on starting them back up 1 of the 3 seems to have lost either it's parameters, or the controller has gone dizzy, it's not giving any readings just sits there with little yellow caution signs.

This is now making the 2 others alarm due to the Dacnet. Denco support aren't helping now it's Flakt group and these are GEA units.
