INSTALLATION GUIDELINES
- Prepare the cut-out with proper dimension as shown in figure.
- Remove clamp from Controller.
- Push the Timer through panel cut-out and secure the Controller in its place by tightening the side clamp.
SAFETY INSTRUCTION
MECHANICAL
- Ambient temperature and relative humidity surrounding the Controller must not exceed the maximum specified limits.
- The Controller in its installed state must be protected against excessive electrostatic or electromagnetic interferences.
ELECTRICAL
- The Controller must be wired as per wiring diagram & it must comply with local electrical regulation.
- The Electrical noise generated by switching inductive loads might create momentary Fluctuation in display, latch up, data loss or permanent damage to the instrument. To reduce this use snubber circuit across the load.

USER LIST : To access the user list Press & Release SET key once.
Parameter | Display | Range | Description |
Control Set Point | ![]() | LSPL – HSPL | User can change the SP value using UP/ DOWN and SHIFT keys. Holding the key will change the value at a faster rate. Press SET key to store the desired value. |
CONTROL LIST: To enter in this mode press SET & DOWN key simultaneously for 3 sec.
Parameter | Display | Range | Description | Default |
Lock Code | ![]() | 1 – 9999 | Set this parameter to 15 (Default LOCK CODE) to access Control List. User has a choice to set different Lock Code via USER LOCK CODE in Config. List. | 15 |
Propor tional Band | ![]() | 0.5 to 99.9°C | This parameter will be prompted only if selected control action is PID. It sets bandwidth over which the output power is adjusted depending upon the error (SV-PV). The value of this parameter is automatically set by Auto tune function. | 5.0°C |
Integral Time | ![]() | 0 to 9999 Sec. | This parameter will be prompted only if selected control action is PID. It sets the time taken by PID algorithm to remove steady state error. Value of this parameter is automatically set by Auto Tune function. If set to ‘0’, this function will be disabled. | 240 |
Derivative Time | ![]() | 0 to 300 Sec. | This parameter will be prompted only if selected control action is PID. It defines how strongly the Controller will react to the rate of change of PV. Value of this parameter is automatically set by Auto Tune function. If set to ‘0’, this function will be disabled. | 60 |
Cycle Time | ![]() | 0.5 0.User to 99.9 Sec. | This parameter will be prompted only if selected control action is PID. can set this value based on process being controlled & type of Output being selected. For Relay 0/P, cycle time should be more 12sec & for SSR 0/P, cycle time should be less than lOsec. | 16.0 Sec. |
Output Power Limit | ![]() | 0% to 100 % | This parameter will be prompted only if selected control action is PID. This parameter will decide the maximum output power in % applied to the load. | 100% |
Output Off | ![]() | 1 to 10 | This parameter will be prompted only if selected control action is PID. With this parameter 0/P will be Completely OFF after the Set Point + Offset Value. If Disable, 0/P will act Depending upon the PID Value after Set Point achieved. | Disable |
Tune Offset | ![]() | 50 % to 100 % | This parameter will be prompted only if selected control action is PID. This parameter allows the User to carry out Auto Tuning function below the set point. (If Tune offset is 50 % tuning will be carried out at 50 % of the set point and if 100 % tuning will be carried out at 100% of the set point.) | 100% |
Control Hys. | ![]() | 1 to 25°C | This parameter will be prompted only if selected control action is ON-OFF. It sets the dead band between ON & OFF switching of the Output. Larger value of hysterisis minimize the number of ON-OFF operation of load.This increases life of actuators like contactors but also produces large errors (between PV & SV). | 2°C |
Delay | ![]() | 0 to 500 Sec. | This parameter will be prompted only if selected control action is ON-OFF. It sets the main output restart time where 0/P once turned OFF will turn ON only after restart time, regardless difference between PV & SP in Heat or Cool mode. If set to ‘0’, 0/P will be switched without delay. Also, Delay will be applicable in case of every power ON. | 0 Sec. |

Parameter | Display | Description | Default |
Auto Tuning Mode | ![]() | This function will be executed only if selected control action is PID. Auto-tuning function is enabled by setting this parameter to ‘YES’. The decimal of LSB flashes till Auto tuning function is in progress. During Auto-tuning, Controller learns the process characteristics by itself & calculates required P, I & D values. User can cancel or abort this feature by setting this parameter to ‘NO’. | No |
USER GUIDE:
ON-OFF ACTION: In this mode, Output (Relay/SSR) remains ON till actual temperature reaches to the set point value. On reaching SP, Output turns OFF & remains OFF till actual temperature drops down (in Heat logic) or raises (in Cool logic) equal to hysterisis set by User. (As shown in Fig : 3.1 & 3.2)
AUTO TUNING MODE: In this mode, Controller learns the process characteristics by itself and calculates the required P,I & D values. It can be performed at any time after power ON but, it is best to start it when the process is at Ambient temperature in order to minimize overshoot & undershoot. Auto tuning is applied in case of :
- Initial set up for a new process.
- Substantial change in SP from previous auto tuning value.
- Control accuracy is not satisfactory.
If the control performance by using auto-tuning is still unsatisfactory, User can apply the further adjustments of P,I & D values as shown below
Adjust | Symptom | Solution |
Proportional Band | Slow Response | Decrease PB |
Over Shoot or Oscillations | Increase PB | |
Integral Time | Slow Response | Decrease Int |
Instability or Oscillation | Increase Int | |
Derivative Time | Slow Response or Oscillation | Decrease Dt |
High Over Shoot | Increase Dt |
