Function: Default (Normal) display.
When set to,
(0) = Room Temperature.
(1) = Compressor Set Point.
Function: This parameter is used to delay the
display of temperature 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.
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.
In Cooling mode, Display Delay parameter is applicable when
Temperature is increasing (rising). When Temperature is
decreasing (falling) this parameter will not be applicable.
In Heating mode, Display Delay parameter is applicable when
Temperature is Temperature is decreasing (falling). When
Temperature is increasing (rising) this parameter will not be
applicable.
Function: To activate alarm.
When set to,
(0) = Alarm Relay is disable for all Faults.
(1) = Alarm Relay will be active for both Ht, Lt and other
faults.
(2) = Alarm Relay will be active for Ht and other faults
except Lt.
(3) = Alarm Relay will be active for Lt and other faults
except Ht.
Note: When AL parameter is Set to enable, Alarm Relay will
Activate for Probe Fail and Auxiliary Digital Input Fault.
Function: To set alarm polarity.
When set to,
(0) = Alarm activated at NO.
(1) = Alarm activated at NC.
Function: This parameter is used to set the Time
Delay at Power ON for Alarm Indication.
Example: If this parameter is set to 20 Minutes, once the controller
is powered ON, no Fault Indication will be activated for 20
Minutes.
Alarm Delay is used only for High Temperature and Low
Temperature, but not for Control Probe Fails.
If Control Probe Temperature reaches or goes above P2 parameter
value, High Temperature ( ) Fault will be displayed.
If Control Probe Temperature reaches or drops below P3
parameter value, Low Temperature ( ) Fault will be displayed.
Differential of 1°C is considered for clearing the fault.
Function: To set controller resolution.
This parameter when set to 0.1, it will take all parameter in 0.1
0
C
resolution.
This parameter when set to 1, it will take all parameter in 1
0
C
resolution.
Note: Temperature and parameter will also change accordingly.
Function: To change Password.
User cannot enter into Program Mode & Set Mode, if correct
Password is not entered.
If the password is kept other then 0, user need to enter correct
Password to enter into Set/Program Mode.
If Password is 0, user can directly access Set/Program Mode.
Function: To lock keypad.
This parameter is used to lock the keypad so that tampering is not
possible by by-standers.
(0) = keypad unlocked
(1) = keypad locked
When locked all parameters can only be viewed, but not modified.
Note: If LP parameter is set to and if user tries to change any
parameter value, " LP " will flash on the display.
Function: To restore default settings of the
controller.
When set to 1, All Parameters are programmed to Factory Set
values.
Useful to debug setting related Problems.
When set to,
0 = FS is inactive.
1 = FS as per Default value.
Function: To end programming.
To end
programming
press "SET"
key
Once the key is pressed, the controller goes into
the normal mode and displays the temperature
and all settings are recorded.
Temperature above the maximum
high temperature limit.
Temperature below the minimum
low temperature limit.

Password Function
• In Programme Mode:
Touch & hold " " key for 2sec. Display will flash "P2"
parameter if "PA" value is kept "0". If other than "0", then
"PA' and "0" will flash. Use " " and " " keys to enter the
password. On entering correct value, display will flash the
first parameter "P2". User can scroll through parameters
using " " or " " keys.
• In Set Mode:
Touch & hold "SET" key for 2sec. Display will flash set point
value if “PA” parameter value is kept to “0”. If other than
“0”, then display will flash “PA” and “0”.
Use " " or " " to enter the password. On entering
correct value, display will flash set point value. User can set
desired value using " "or " " keys. To save the modified
value use "SET" key.
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 1 second 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 Control
Probe Temperature.
• How to reset the Logged Values:
While the Display is showing the logged values, if user touch
& holds the "SET" key for 1 seconds, the logged values will be
cleared and "LrS" will be displayed.
Log Values will get reset after Power ON/OFF.
