utes per repeat for the heat

outputs.

0.00 to 99.99 minutes/per

repeat (0000 to 99990)

0.00: disabled

0.00 *224, 225 R/W At least one output is

set to [hEAt], [ht;m]

is set to [`PId],

and [Unit] is set to

[``SI].

Rate Heat

Set the PID rate time in min-

utes for the heat output.

0.00 to 9.99 minutes (0000

to 9990)

0.00: disabled

Set the PID derivative time in

minutes for the heat outputs.

0.00 to 9.99 minutes (0000

to 9990)

0.00: disabled

point.

Heat Hysteresis

Set the control switching hys-

teresis for on-off control. This

determines how far into the

Note: Parameters appear in the Operations Page only if activated from the programming page. See page 22 for Operations Page defaults.

Note: Some values will be rounded off to fit in the four-character display. Full values can be read with Modbus. All temperature param-

eters through Modbus are in °F, by default.

* 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-_ _ _ _- _ _ _ _ ).

**** This value multiplied by 100 equals the percent power.
