(Probation time
A probation time can be set (F87), the controller can add up the running time after power is on, if
the accumulative running time is over the probation time, the controller will stop and display the alarm
code A99, if you want to eliminate the limit of probation time, set the F87 to “OFF”, also you can use the
F86 to clear the accumulative running time, and you can try to use it again. The parameter F85 can be
used to examine the accumulative running time of the controller (hour).
(Password
In order to prevent irrespective persons from changing the parameters, you can set a password
(F80), and if you have set a password, the controller will hint you to enter the password after you press
the key “M” for 5 seconds, you must enter the correct password, and then you can set the parameters. If
you don’t need the password, you can set F80 to “OFF”. Notice that you must remember the password,
and if you forget the password, you can not enter the set state.
