No heat one zone due to air pocket in water line, purged, tested, zone operational, also found clogged air vent not helping to remove air pockets from lines, replaced, tested all four zones, also adjusted temp for indirect water heater down to 120degrees, customer stated hot water is way to hot, all zones operational. Need to schedule appointment for comfort advisor to come out and give an estimate to install ductless system for home, also need to order outdoor temp sensor for boiler, sensor needs to be replaced, not reading proper temp outside, and need to re-evaluate boiler with tech support to make sure all settings are set up correctly.
