Description
[SP; L o]
Set Point Low Limit
[SP.Lo]
Set the low range for the set
point.
[SP; h i]
Set Point High Limit
[SP.hi]
Set the high range for the set
point.
[Ftr; E ]
Input Filter
Select filtering action.
[Ftr.E]
[FLtr]
Filter Value
[FLtr]
Set the input filter value.
[Ot`1]
Output 1 Function
[Ot 1]
Set Output 1 function.
[Ctr1]
Control Method 1
[Ctr1]
Set output 1 control type. This
parameter is only used with PID
control, but can be set anytime.
[Ftb1]
Fixed Time Base 1 (Cycle
Time)
[Ftb1]
Set the time base for Fixed Time
Base Control.
Note: Some values will be rounded off to fit in the four-character display. Full values can be read with Modbus. All temperature pa-
rameters through Modbus are in °F, by default. Writing to register 18 will toggle between °F and °C.
* Low register numbers contain the two higher bytes; high register numbers contain the two lower bytes of the four-byte integer.
Decimal precision is implied at three decimal places unless otherwise noted.
** Static set point version only (SD_C-_ _ _ _- _ _ _ _ ).
*** Profiling version only (SD_R-_ _ _ _- _ _ _ _ ).
