There was Faulty Adaptive Control Display unit on RTAC200 Trane Chiller sticker on backside is X13650827-06 I replaced it with same number X13650827-06 from ebay. when I give it 24Vdc power it shows configured as CH531.When I installed on chiller in Report it is not showing Temperature and Pressure readings, do I need to download some software or there is some special procedure.I thought it is only plug and play display.Any help will be appreciated.Thanks.
