  No need to feed input while calibrating Rx. o/p. just make the value in calibration 

mode equal to the displayed value.

7. CONTROL FUNCTION

 

  Model LC5296-XP-DC is microcontroller based ON-OFF Controller  

7.1  ON/OFF Control 

ON/OFF Controller is the simplest form of temperature control device. The output from 
the device is either on or off, with no middle state. An on-off controller will switch the 
output only when the temperature crosses the set point. For heating control, the output 
is on when the temperature is below the set point, and off above set point. 
 
Since the temperature crosses the set point to change the output stage, the process 
temperature will be cycling continually, going from below set point to above, and back 
below. In cases where this cycling occurs rapidly, and to prevent contactors and valves 
from getting damaged, an on-

off differential, or “hysteresis,” is added to the controller
