Loop Menu
[`r; E n] Loop
Remote Enable
[ r;En]
Switch control to the remote set point.
[`r; t y] Loop
[ r.ty] Remote Set Point Type
Select how the remote set point will be deter-
mined.
[`C; M ]
Loop
[ C.M] Control Mode
Select the method that the controller will use to
control.
[A; t SP] Loop
[A.tSP} Autotune Set Point
Set the set point that the autotune will use, as a
percentage of the current set point.
[`AUt] Loop
[ AUt] Autotune Request
Start an autotune. While autotune is active, the
Home Page will display [Attn] [tUn1]. When
the autotune is complete, the message will clear
automatically.
[`C; S P] Loop
Closed Loop Set Point
[ C.SP]
Set the set point that the controller will automati-
cally control to.
[`id; S ] Loop
[ id.S] Idle Set Point
Set a closed loop set point that can be triggered by
an event state.
[`h; P b] Loop
Heat Proportional Band
[ h.Pb]
Set the PID proportional band for the heat outputs.
[`h; h y] Loop
[ h.hy] Heat Hysteresis
Set the control switching hysteresis for on-off con-
trol. This determines how far into the "on" region
the process value needs to move before the output
turns on.
[`C; P b] Loop
[ C.Pb] Cool Proportional Band
Set the PID proportional band for the cool outputs.
[`C; h y]
Loop
[ C.hy] Cool Hysteresis
Set the control switching hysteresis for on-off con-
trol. This determines how far into the "on" region
the process value needs to move before the output
turns on.
[``ti] Loop
[ ti] Time Integral
Set the PID integral for the outputs.
[``td]
Loop
[ td] Time Derivative
Set the PID derivative time for the outputs.
Note: Some values will be rounded off to fit in the four-character display. Full values can be read with other interfaces.
If there is only one instance of a menu, no submenus will appear.
