Appendix E.3. Starting/Stopping DAP devices
The DAP-Config command is an exception to the above notes. A read is not required.
The DAP Config command is used to turn off/on DAP units. The Command uses two
consecutive array elements. The first is the zone, the second is the inhibit command. Valid
zones are 0-63.
If any inhibit bit (bits 0-5) is set then the unit will not run. If bits 0 to 5 are off then the unit
will run. Bits 6& 7 are used for display only on the DAP panel.
0x01 - Inhibit Cooling
0x02 - Inhibit Heating
0x04 - Inhibit Humid
0x08 - Inhibit Dehumidification
0x10 - Inhibit fan
0x20 - Reserved
0x40 - Network Standby - Display on panel (only has no effect on unit)
0x80 - Network off inhibit is active - display only - no effect on operation
This function should be used as a wrbc/x. When the driver encounters this command it
reads the associated Data Array, loads the two elements found at the array offset into the
message and transmits the message. The driver does not set any Data Array elements to
confirm that the command concluded successfully.
Additional information is provided in Appendix B.10
Appendix E.4. DAP Unit Errors
Dap-Stat Query
The following table provides information on the storage of errors obtained in response to the
Dap-Stat Query. Note that the errors are stored two ways – One storage method stores 8
alarm bits at a time in a single array element (stored as byte values) – The other method
stores each alarm at a different location in the Data Array.
