I have a first generation microtech processor on this McQuay ALR130 air cooled chiller. The problem is I want to change the lvging evap water temp set point to a higher setting, I can use the default password which is enter 4 times, lets me in allows me to go up from 44 degrees to the setpoint I now want which is 48 degrees, I hit enter it shows the 48, after a few seconds it resorts back to 44. Its funny cause I can change all the other setpoints and it stays at my changes I made except for the chilled water leaving set point. Help!
