Automatic Setpoint Change Mode
Automatic Setpoint Change (ASC) Mode allows up to 6 setpoint changes to be pre-programmed over defined
periods of time using function code Cd53. Refer to
for detail description of Cd53 menu selections and
display values.
NOTE
Automatic Setpoint Change (ASC) and Automatic Cold Treatment (ACT) and can not be enabled
simultaneously. Setting one will deactivate the other.
NOTE
Before starting this procedure, be aware that inaction to confirm a menu selection in a timely fashion
will result in the procedure being stopped and the menu will return to the top level.
Turning On and Setting ASC Mode:
1. Press the CODE SELECT key.
2. Use the Arrow keys to bring up Cd53 and press the ENTER key.
3. The display will show | “ASC” | “OFF” |.
4. Use the Arrow keys to select “On”, then press ENTER.
5. The display will show | “nSC” | “#” |, where # is the number of setpoint changes.
For example, if 3 setpoints are chosen, 2 setpoints will be established along with associated days that
they are to be active. Then, the 3rd setpoint is chosen for the temperature desired after this procedure is
complete.
6. Use the Arrow keys to select the desired number (1-6) and press ENTER to confirm.
7. The display will show | “SP 0” | “#.#°C” |, where # is the desired setpoint temperature. This is the first
setpoint to be programmed.
8. Use the Arrow keys to select the desired setpoint and press ENTER to confirm.
9. The display will show | “dAY 0” | “#” |, where # is the amount of days to keep this setpoint active.
10. Use the Arrow keys to select the desired number of days (1-99) and press ENTER to confirm.
11. The display will return back to | “SP #” | “#.#°C” |.
12. If there was more than 1 programmed setpoint chosen (nSc value), then the process will repeat itself of
selecting a setpoint along with days to run that setpoint. Repeat steps 7-10 for all setpoints.
If there are no more programmed setpoints, then this last setpoint will be for unit temperature after ASC
has completed. Continue to the next step.
13. Use the Arrow keys to select the setpoint after completion and press ENTER to confirm.
14. The Cd53 menu is returned to the top level and the display will show | “Cd 53” | “0 0“ |. Upon exiting Cd53
and then returning, the display will now show | “Cd 53” | “# #“ |, where the right display is the countdown
timer of days and hours remaining.
15. While ASC Mode is in progress, the user can choose to view only the settings chosen for ASC. Once at
Cd53, “On” is flashing. Press ENTER and then continue to press ENTER to toggle through all of the current
selections. No edits will be allowed.
16. While ASC Mode is in progress, the user can choose to edit the settings for the ASC Mode currently in
progress. Once at Cd53, “On” is flashing. Use the arrow keys to display “OFF” and press ENTER. Then, use
Arrow keys to select “On” and press ENTER. The procedure will start over to create settings for ASC mode.
Repeat this procedure starting at step 5.
