adjusting the control. Verify that the control is displaying the desired temperature units
before setting the setpoint.

2. Press the Menu button again. The current setpoint is displayed.
3. Press the Up or Down button to adjust the setpoint temperature.
4. Press the Menu button to save. The display then returns to the sensor
temperature
.
Note : If the Menu button is not pressed after changing the setpoint, the control reverts to
the setpoint value previously programmed into the A419 control.
