Note The process controller automatically checks to ensure that

the entered data matches other related variables. If a wrong

configuration is entered, “WRONG” blinks on the LCD to

prompt the user. The correct configurations are the following:

If M1=/ 0 then S1<HA, S1>LA;

If M2=/ 0 then S2<HA, S2>LA;

For models other than HI 21523:

If M1= 1 then S1-H1>LA;

If M1= 2 then S1+H1<HA;

If M1= 3 then S1+D1<HA;

If M1= 4 then S1-D1>LA;

If M2= 1 then S2-H2>LA;

If M2= 2 then S2+H2<HA;

If M2= 3 then S2+D2<HA;

If M2= 4 then S2-D2>LA;

If M1= 1 and M2 = 2

then S1-H1>S2+H2, S2>LA, HA>S1;

If M1 = 2 and M2 = 1

then S2-H2>S1+H1, S1>LA, HA>S2;

If M1 = 3 and M2 = 2

then S1>S2+H2, S2>LA, HA>S1+D1;
