If selected, soak timer will increment (from 0 to set value)
(Note:- User can alter the new time value which should be > elapsed time even if
soak timer is running. If user sets new time value < elapsed time, running timer
will be terminated & End of soak Strategy will be executed.
If selected ,soak timer will decrement (from set value to 0).
(Note:- User can alter the new time value even when soak timer is running. In this
case, balance time of previous set value will be ignored & new cycle will be

User can define 4 different modes to start the soak timer as follows : -
In this mode, Timer will start after pressing START key for 3 sec., irrespective of
PV.
In this Mode, after power ON Timer starts when PV >= SV. To continue with next
cycle, user has to either switch Power on & off
OR
press START key for 3 sec
when STRT message is displayed on the lower display.
In this Mode, Timer will start only after pressing START key for 3 sec & PV>=SV
for any of the following conditions.
(1) At every Power ON.
(2) Completion of current soak time cycle.
(3) Power failure during soak time is in progress.

STRATEGY
It defines the behaviour of the controller at the end of soak timer cycle . Options
are as below. If selected, the controller maintain PV at SP indefinitely irrespective
of start or end of a soak timer.
The controller de-energizes OP1 as soon as the soak time is over. Here upper
display will continue to show PV & lower display will show message "start".Next
cycle will start only when user press START key for 3 sec.
The controller energizes OP2 for a time period programmed via (StdL) parameter
at the end of a soak time cycle. User can utilise OP2 for audio/visual indication.
The controller executes both, the Heater OFF and Alarm ON function as
described above.
