If you are experiencing E10 faults caused by the thermal limit in the compressor being tripped and the unit is operating in or
close to the "Sensitive Operating Range" you may need to increase load water flow or decrease the set point. Increasing the
load water flow will lower the discharge pressure and compressor temperature.
