For this evaluation the customers furnace was cooling however the systems blower wouldn't turn off. The thermostat was set for electric system and not a furnace so once I changed the setting and changed the blower off delay to 60s instead of 180s the system shut off like it was supposed to. I tested the system multiple times and the system continued to shut off like like it is programmed to. Customer would like to have a plumber come out Monday 14 April to give him a quote to replace some toilet parts and also look at his cast iron plumbing.
