Relating Conditions with Programs 

 

Conditions  can  be  used  for  causing  programs  to 

start/  stop

  or  for 

enabling  / 

disabling

 their operation.  

 

In  this  chapter  we  shall  explain  how  conditions  can  be  related  with  irrigation 

programs,  however  prior  to  using  the  conditions  they  must  first  be  defined. 

Conditions definition is done at the 

CONDITIONS LIBRARY

 (see below). 

 

 

 
 

 

 

The 

CONDITIONS LIBRARY

 can be reached through the               submenu, or by 

the shortcut 

F3 = "Cond" 

that is revealed when

 

the cursor is located at the column 

of conditions number. 

 

 

 

 

 

 

 
 

 

 

 

 

 

By specifying the ordinal number of the desired condition in the row of the desired 

action  we  create  a  relation  that  will  cause  the  action  to  be  executed  when  the 

condition becomes TRUE. For example in the above screen, program 1 will be started 

by condition 1 and will be stopped by condition 3 when they become TRUE. 

 
 

 

Notice that:  

 

  The 

Enable

  action  will  not  start  the  program;  it  will  only  permit  the 

program  to  run as  long  as  the  condition  is  TRUE  and  make  it  wait  as 
long  as  the  condition  is  FALSE.  Same  way  the 

Disable

  action  will 

cause the program to wait as long as it is TRUE and let it run as long 
as it is FALSE. 

 
 
 

Shortcut to 

Conditions Library

 

The current status of the 

condition is false

 

 

Condition No. 1 when 

becoming TRUE will 

cause the program to 

start

 

Possible actions on 

the program
