• In the remote SP mode, the remote SP can be monitored on the
No.2 display for PV/SP . In the local SP mode, the remote SP can be
monitored in the "remote SP monitor" parameter.
• When the local SP is switched to from the remote SP when the SP
tracking function is enabled, the local SP is changed so that the
remote SP value is held at the SP value used immediately before
switching.
To use the SP tracking function, set the "SP tracking" parameter to
"ON".
• The following figure shows how SP tracking works when the SP mode
is switched.

SP mode LSP
(1) When the remote SP is switched to when the set point is "LSP1",
the SP is switched to "RSP2".
(2) The SP shifts according to remote SP input.
(3) When the local SP is switched to, the set point becomes "LSP2" if
the SP tracking function is enabled. If this function is disabled, the
SP will be switched to "LSP1".
• When the local SP is switched to the remote SP , the SP ramp will
operate if the SP ramp function is enabled.
• During auto-tuning, remote SP input is not accepted. Auto-tuning is
executed on the set point at the start of auto-tuning.
• Remote SP is not subject to the standby sequence reset conditions.
