5.4 SP Group (G.SP)
This parameter sets the running mode to RUN or STOP. In STOP mode, outputs are
turned off, and no set point is maintained.
This parameter selects which set point is active. There are four programmable set points,
and one for use with SYNC-SLAVE communication. It can be set to RSP, SP1, SP2, SP3,
or SP4. Its default setting is SP1.
This parameter sets the value of each of the 4 programmable set points that can be
selected to run. The parameter SPSL selects which set point to use.
This parameter sets a high limit on what the set points can be programmed or changed to.
This value may reset if the type of input is changed, or if parameter IN.RH or IN.RL
(IN. SH or IN.SL if input type is mV or V) is changed.
This parameter sets a low limit on what the set points can be programmed or changed to.
This value may reset if the type of input is changed, or if parameter IN.RH or IN.RL
(IN. SH or IN.SL if input type is mV or V) are changed.
This parameter sets the time unit the controller uses for parameters with time components.
This can be set to the format of HH.MM (hours.minutes) or MM.SS (minutes.seconds).
Its default setting is HH.MM.
This parameter to sets the SP to ascend or descend gradually over time, dependant on the
new SP selected. U.SLP (rate of ascension) and D.SLP (rate of descent) are the rate of
change over time (time units set by parameter TMU) of the set point when the set point is
changed. When U.SLP and D.SLP is set to OFF, the new SP is set instantly. The default
setting of U.SLP and D.SLP is OFF.

NOTE
When using the communication option for Sync-Slave control, the slave
controllers must have SPSL set to RSP.

NOTE
Parameters S-TM and P-TM are not linked to TMU. The time unit setting
of those parameters is always HH.MM (hours.minutes).
