Response Format The response returned for this command is shown below. This response as-
sumes that the header code in the command block was transmitted and read
normally and that the end code is 00. If the end code is not 00, the shift value will
not have been read and the end code will be followed immediately by a frame
check sequence (FCS). If the header code in the command block was not recog-
nizable, a header code of IC will be returned without an end code (see
Section
4-1-2 End Codes for the IC header code response format).

End Codes If an end code of 00 was returned in the response, the command was executed
normally. If the end code is not 00, the desired data will not have been be read.

Section 4-1-2 End Codes for a description of the other possible end
codes and their meanings.
4-2-20 Hysteresis Write: WH
This command is used to set the hysteresis used in ON/OFF operation. Doing so
will result in an error and the end code 01 will be returned.
Note It cannot be used during autotuning.
Command Format The format for this command is as shown below. The unit number, memory bank
number, and control point must be specified along with the hysteresis. The hys-
teresis is given in three digits to an accuracy of one-tenth of a degree.
