Command Format The format for this command is as shown below. The number of the unit whose
points are to be set must be specified. Each of the bits 0 through 7 of the setting
data is assigned to a control point as shown below. If the bit for a control point is
OFF (0), heating operation (the default) is specified. If the bit is ON (1), cooling
operation is specified. Bits not used by the specified unit must be set to 0. An
error with an end code of 15 will result if these bits are not 0.

FCS
To determine the value to be input for the desired setting, convert the bits to two-
digit hexadecimal values and then convert the digits independently to ASCII
code. For example, the value to change all points for a 6-point E5ZD to cooling
operation would be 3F
hex
. A 3 in ASCII is 33 in hexadecimal, and F converts to
46. The two digits of the setting would thus be 33
hex
, 46
hex
.
Command Examples The following command is used to set points 0, 2, and 4 of unit 2 for heating oper-
ation and points 1, 3, and 5 to cooling operation

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. If the header code in the command block was not recognizable, 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 written.
