This parameter will appear only if Control logic is Heat-Cool.
If Enabled, User can set Diff. mode for OUTPUT 2 in USER list. 

If disabled, User can not set Diff. mode for OUTPUT 2 in USER list.

This parameter will appear only if Control logic is Heat-Cool. 
OP2 will be OFF at A OP2C value  irrespective of output 2 mode.

This parameter allows the user to select output 2 as an ‘Auxiliary’ control.
For options refer Table 3.

This parameter allows the user to select output 2 as an ‘Alarm’ control.
For options refer Table 4.

This parameter allows the user to select output 2 as a ‘Soak’ mode.
For options refer Table 5.

This  parameter  allows  the  user  to  select  output  2  to  function  as  both  ‘Alarm’  & 
‘Soak’. For options refer Table 4 & 5.

If Enabled, User can View & edit the Set point (SP1) in USER list. 

If  disabled,  User  can  only  View  the  Set  Point  (SP1)  but  Can  not  edit  it  in  USER

When NONE is selected, Output 2 will be permanently de-activated.

This parameter helps in selecting the functionality of Digital Input.

When NONE is selected, Digital Input will be permanently de-activated.

By selecting this parameter, Digital Input can be used as Water Level Indicator input.

By selecting this parameter, Digital Input can be used to detect whether the door is 
open or closed.

By selecting this parameter, Digital Input can be used to start soak timer.

By  pressing  DOWN  key,  Lower  display  will  Toggle  between  SP1-value,  SP2-
value, Alarm SP-Value(AL.SP) & Timer-value(SOAK).

By this parameter Lower display will only show the SP1-value.

By this parameter Lower display will only show the Timer value(SOAK TIME).

By this parameter Lower display will show Setpoint till soak timer has not started 
and afterwards, it will display the Timer value(SOAK TIME).
This parameter will appear only if Output 2 is set as SOAK/ AL.ST

Digital Input will be detected after selected timing.
The range of Digital Input timing will be from 0 to 99 sec.

Alarm output will be generated after the completion of alarm time and detection of 
Digital Input.
The range of Alarm Input timing will be from 0 to 99 sec.
