4. QUICK SETPOINTS MENUS
There are 4 different menus dependent to Temp Cntrl. Temp Cntrl (temperature control) is part of unit configuration. To access/
change Temp Cntrl, go to Service Menu / Config / Edit Equip Config.
To change the value of a setpoint, use the up or down arrow button to find the desired setpoint. Press the enter button, then the up
arrow button to increase or the down arrow button to decrease the setpoint. When you get the desired value, press the enter button.
Use the up or down arrow button again to move to other setpoints or press the Esc button to get out of the Quick Setpoints Menu
