Changing the Setpoint
From the Standard Display, press the SETPOINT soft key.
The setpoint display appears as shown ( Setpoint Display).
The - and + soft keys are used to increase or decrease the setpoint until the desire setpoint is shown. The setpoint has been changed to 40°F using the + key ( Increase Setpoint).
The YES and NO soft keys confirm the setpoint change. When the desired setpoint has been selected using the + and/or - keys, press the YES soft key to confirm and load the new setpoint. If the setpoint is changed using the + or - keys, the change must be confirmed or rejected by pressing the YES or NO soft key within 10 seconds of changing the setpoint.
Failure to confirm the new setpoint by pressing YES or NO within 10 seconds of changing the setpoint will result in no setpoint change. In addition, Alarm Code 127 Setpoint Not Entered is set, to indicate that the setpoint change was not completed.
After the YES soft key has been pressed, the display briefly shows PROGRAMMING NEW SETPOINT - PLEASE WAIT. The display then confirms the new setpoint for several seconds.
If the NO soft key is pressed, the display will briefly show SETPOINT NOT CHANGED and return to the Standard Display. The Standard Display will show the old setpoint. The display then returns to the Standard Display showing the new setpoint. The arrow now points up to indicate that the unit is heating ( Standard Display, New Setpoint).
