keys. To save the modified value use "SET" key.
How to reset the Logged values
While the display is showing the logged values, if user
touch & hold the "SET" key for 1sec, the logged values will
be cleared and "rS" will be displayed.
Log Values will get reset after Power ON/OFF.
High and Low temperature logging function
How to see the logged values:
LL : Last Low temperature
LH : Last High temperature
Touch and hold " " key for 1sec. display will flash “LL” and
the corresponding temperature for 4 seconds. After this,
display will flash “LH” and the corresponding temperature for
4 seconds and come out of Log mode and will display

User selectable Default values
This can be done by following steps:
User can set their own set of Default Set values for all parameters. If
user wants to activate this feature, Program mode must be accessed
and then change Factory set (FS) parameter accordingly.
Modify values of set point and other parameters as desired by
entering set mode and program mode respectively.
Select FS parameter and touch "SET" key. While display
flashing “0” , touch and hold " " for 10sec. Controller will flash
"-2". Then touch "SET" key. All the user defined parameter
values will be stored as ‘User Default set’.
If user wants to use this set of parameters, access Program
mode and set the FS parameter to "2". Controller will restore the
user defined parameter values.
(Note: Keypad parameter LP and User lock parameter will be
taken into consideration while modifying this parameter.)

Function : This parameter is used to delay
the display of temperature update by the
set in this parameter.
Each value corresponds to 5 seconds, if the value is set to 1, it
corresponds to 5 seconds, if it is set to 2, it corresponds to 10
seconds and so on.

For example, if this parameter is set to 1, temperature on the
display will be updated after 5 seconds. The same value will be
considered for calculation and logging.
Display delay parameter is applicable only when temperature
is increasing (rising). When temperature is decreasing (falling)
this parameter will not be applicable.
If this parameter is set to 0, this feature will be disabled.

Example: If this parameter is set to 20 minutes, once the
controller is powered ON, no fault indication will be activated
for 20 minutes.
If Control Probe Temperature reaches or drops below P3
parameter value, Low Temperature (Lt) fault will displayed.
If Control Probe Temperature reaches or goes above P2
parameter value, High Temperature (Ht) fault will displayed.
Alarm delay is used only for High Temperature and Low
Temperature, but not for Room Sensor fail.
