Upon arrival I was told that customer was having a tough time regulating space in all areas, thermostat temperature on schedule seems to be changing or not set correctly. Supervisor asked for me to set it to 72 at all times. Found schedule dropping indoor temp down to 65 at night on all thermostats. Removed time period entirely so all thermostats only have 1 scheduled time period, making setpoint always at 72. Didn’t want to remove schedule option entirely in case they want to alter it in the future. Also went into installation settings and found adaptive recovery was enabled on each thermostat. This setting turns the system on to get temperature to setpoint before time period starts. I turned this off so thermostat won’t start System earlier than they want. Once corrected I called for heat on all thermostats and checked operation on roof. Found all units operating normal.
