Daikin DM97 modulating natural gas furnace with DZ17 heat pump Had a bunch of stored comm faults, only variations were thermostat comm fault and eev comm fault. Found lots of high voltage and low voltage wires following each other inside and outside of the furnace cabinet. Re-routed line voltage lines away from comm wiring Twisted unused stat wires with a wire nut at the stat and grounded the same conductors inside the furnace to act as a shield. Also wired humidifier into the furnace HUM relay and enabled HUM control on the Daikin One stat. Cleared faults Set system to heat No active faults at this time
