SET UP
The first will evaluate as TRUE if Boolean 1 is TRUE and will evaluate as FALSE
if Boolean 1 is FALSE. The second will evaluate as TRUE if Boolean 2 is FALSE
and will evaluate as FALSE if Boolean 2 is TRUE.
Local : The local switch can also be read. The following two conditions are the only
allowed conditions for the Local switch.
L00H
L00L
The first will return TRUE if the local switch is high and FALSE if the local switch
is low. The second will return TRUE if the local switch is low and will return
FALSE if the local switch is high.
Reset : When the system is resetting to default settings (only on boot) then the reset
conditional is set to true. The following two conditions are the only allowed condi-
tions for the Reset switch.
R00H
R00L
The first will return TRUE if the reset switch is high and FALSE if the reset switch
is low. The second will return TRUE if the reset switch is low and will return
FALSE if the reset switch is high.
Clauses : Clauses perform actions such as setting a Boolean value, setting the state
of a relay or executing the event of a schedule. Each item in a clause statement is
separated by a comma and is executed in order from left to right.
Relays : Relays can be turned on, off or pulsed from a clause. The duration for the
relay pulse is configured under "Relay Setup" on the "I/O Setup" page. The relay
clause contains 3 parts, the 'R' the relay number and the action.
R01H - will turn Relay 1 high
R01L - will turn Relay 1 low
R01P - will pulse Relay 1
Turning a relay high or low that is already in that state will have no effect.
Booleans : Booleans can be set to TRUE or FALSE from a clause.
B01T - will set Boolean 1 to TRUE
B01F - will set Boolean 1 to FALSE
Events : Events on the Scheduler page can be executed from a macro clause, regard-
less of whether or not the Schedule is enabled. Only the first 99 schedules can be
executed from a clause.
E01T - Will execute Event 1
E01F - Will also execute Event 1
The 3rd parameter of this operation has no bearing.
