Figure 38: Setpoint Changed Using “+” Key
The YES and NO Keys (Figure 39) confirm the
setpoint change. When the desired setpoint has
been selected using the “+” and/or “-” Keys, press
the YES 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 Key within
10 seconds of changing the setpoint. A warning
beep will sound for 5 seconds as a reminder.
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 a setpoint change was initiated
but not completed.
Figure 39: Yes and No Keys
After the YES Key has been pressed, the display
briefly shows PROGRAMMING NEW
SETPOINT - PLEASE WAIT. The display then
confirms the new setpoint for several seconds
(Figure 40):

show SETPOINT NOT CHANGED and return to
the Standard Display. The Standard Display will

The display then returns to the Standard Display
showing the new setpoint. Notice in Figure 41 that
the arrow now points up to indicate that the unit is
heating.
