If yu are unsure abut any f these steps, call a qualified technician fr assistance. Assemble tls Flat Blade Screwdriver Wire cutter & Stripper L L L Make sure yur Heater/Air nditiner is wrking prperly befre beginning installatin f the thermstat. arefully unpack the thermstat. Save the screws, bracket, and instructins. Turn ff the pwer t the Heating/Air nditining system at the main fuse panel. Mst residential systems have a separate breaker fr discnnecting pwer t the furnace. Page 2

Lsen the screws hlding the thermstat base r subbase t the wall, and lift away. Discnnect the wires frm the ld thermstat. Tape the ends f the wires as yu discnnect them, and mark them with the letter f the terminal fr easy recnnectin t the new thermstat. Keep the ld thermstat fr reference purpses, until yur new thermstat is functining prperly. Page 3
