Figure 50: A Typical Setpoint Screen
Procedure for Changing a Setpoint
1. Press the applicable Setpoint Group.
2. Select the desired setpoint by pressing the numbered
Setpoint Field.
3. A password must be entered before changing any
setpoint value. A keypad prompt will appear to enter a
password and then the keypad or drop down menu will
appear to make the desired change. .
Input the appropriate password number. (Use 100 for
operator level. The technician level password number is
only provided to Daikin Applied technicians.) There is a
small delay between pressing the keypad and recording
the entry. Be sure that an asterisk appears in the window
before pressing the next number.
4. Setpoints with numeric values can be changed in two
ways:
• Select the desired value by pressing the numbered
buttons on the Numeric Keypad.
• Press the UP or DOWN button to increase or
decrease the value displayed.
Some setpoints are selectable text menus rather than
numeric values. Select the desired option using the drop
down menu that appears on that particular setpoint.
Toggle between choices using the UP or DOWN button.
If dashed lines appear in the setpoint window it means
that toggling in that direction can go no further, so
reverse direction.
For all of the methods listed above, press ENTER on the
Setpoint Screen to enter the value or CANCEL to cancel
the transaction. The CANCEL or ENTER buttons must be
pressed before another setpoint can be selected.
5. Additional setpoints can be changed by selecting another
setpoint on the screen using the Setpoint Selection
buttons or by selecting an entirely new group of setpoints
using the Setpoint Group buttons.
CAUTION
Many setpoints are interactive. Changes may have an adverse
effect on chiller operation. Only trained operators should be
allowed to change chiller setpoints.
NOTE:
Setpoints that have a technician level password
(T) should only be changed by a Daikin Applied
technician. Contact a Daikin Applied service
representative for more information.
