light moves to the M button. The controller output remains unchanged at the moment of the
transfer.

Manual to Remote Automatic Control:
Click the R button to make this transfer. The red mode
light moves to the R button. The controller output remains unchanged at the moment of the
transfer, so the transfer is bumpless. The new setpoint is real time remote setpoint from the
primary signal. Controller output is calculated based on the measured setpoint and process
variable. Before the transfer, compare the values of remote and process variable displayed in the
window so the impact of the transfer can be estimated before the transfer.

If the option of setpoint tracking is selected, the value of local setpoint is set to the value of

last local setpoint or initial setpoint if this is the first time in local automatic mode since power has
been applied to the SVI.
