to change the “HELD” setpoint if the ramp is on “HOLD.”

However, the ramp time remaining is not changed. Therefore, when returning to RUN mode, the setpoint will ramp at the same rate as prior to local setpoint changes and will stop if the final setpoint is reached before time expires.

If the time expires before the final setpoint is reached, it will jump to the final setpoint.

When the final setpoint is reached, the

“R” changes to “H” in the upper display and the controller operates at the new setpoint.

ATTENTION Any time the local setpoint is different from the final setpoint value and

the RUN/HOLD key is pressed, the ramp will start again.
