When remote switching via discrete inputs is configured and the
signal line is inactive, the controller switches to LSP control. When the
discrete input returns to the opposite state, the controller reverts to
using the RSP value (assuming the R button is still lit).
5.7.1 Local Setpoint (LSP)
When no setpoint options are configured, the controller accepts a
local setpoint (LSP) value, entered with the green increase/decrease
buttons. Set the LSP value according to the instructions in Section 3,
Establishing a Setpoint.
A local tracking option is available for selection when using LSP
control. This option provides automatic setpoint tracking when the
controller has been placed in the manual mode via the manual button.
