Parameter setting instruction:
START/STOP MODE： When set as MANUAL, the
unit will operate according to the keys on the control
panel or remote switch, or perform the switch control in
Modbus protocol. If set as AUTO switch, the set time for

priority system to start, if the start priority is set to
System1, the system1 is always a priority in the system2
to start . Only in the USE ONE SYSTEM set up for
DUAL, this setting be useful.
USE ONE SYSTEM： Dual-system units, in some
cases wish to start a system, another system is not
running. The default case, the two systems can be
running. If the USE ONE SYSTEM is set to SYS1, then
only system 1 is running, the system2 does not run; if the
USE ONE SYSTEM is set to SYS2, then only the
System2 is running, the system1 does not run; if the
USE ONE SYSTEM is set to DUAL, the system1 and
system2 can be running. Only by
USE ONE SYSTEM set up for DUAL, START
PRIORITY is used, otherwise non-functional.
OIL PREHEAT： In some cases the need for debug-
ging start unit, if the use of oil pre-heating will affect the
debugging process. Therefore, through the OIL
PREHEAT will be set to NO, temporarily masked the
oil preheating function.When the debugger has finis-
hed,the
OIL PREHEAT must be set to YES.
START PRIORITY and USE ONE SYSTEM， Only
in the use of dual-system units, units in a single system
does not use. These parameters should be setting in the
two systems are in the case of stop.
