heater for control point 1 of Unit 1.

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 measured
current will not have been returned and the end code will be followed by the error
code (see below). If the header code in the command block was not recogniz-
able, 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).
