Amanda Benson 252-902-6385 Tech confirmed shorted tstat wire between wall and new RTU. 15 volts present on Blue and Green. 28 volts present on W. 8 on Y. Could not get package unit working with existing tstat wire. Tech cut duct detector wire to temporarily mount focus pro tstat inside return panel next to filters. Heat is on 68 and cool is on 73. Need to return to pull new tstat wire and reconnect duct detector. Did not see duct detector location while on site today. Wire runs down return duct.
