Arrived to speak with and educate customer about evolution user interface. Customer was just more comfortable with old tstat. I explained they would lose all the capabilities they paid for if they got rid of user interface. After discussion, I programmed stat for AUTO mode for customer, they were satisfied with solution. Took pics of basement and attic systems. Replaced fernco coupling on basement exhaust flue pipe pics uploaded. Also wrapped condensate dra8n line in attic to stop line freeze in winter as it has a 90% furnace as well. Took pics of all work performed and uploaded pics. Covered under warranty.
