This controller can be applied to two pure superheat control circuits, but only one
EIV feedback can be input (terminal X3). The simulation mode is possible for one
circuit only (for simulation mode, refer to pages 7 and 12).
The superheat controller monitors the temperature differential between the suction
gas temperature and the calculated evaporation temperature (TOH-TO) to maintain
the adjusted setpoint

T.
The electronic injection valve is controlled via analogue output Y1 (Y2 for Circuit 2).
