Upon arrival found unit working fine checked tsat and found bad red wire. Replaced wire with orange at tsat and at AHU. Replaced batter on tstat. Checked pressures and sub cooling and super heat are good. System is running fine since I arrived and even after changing red wire to orange it’s still running fine. I checked the Honeywell red link battery and it does have lithium AA batteries. Informed customer if we have to come back we have to replace the tsat on the wall. I spoke to Wayne and informed him about this call.
