5.7.5 Continuous temperature monitoring using refrigerant temperature sensor
Controller type UK 100 E or KR 160 E
The cooling is controlled according to the temperature of the refrigerant temperature sensor.. If the refrigerant
temperature value reaches the current setpoint, the opening time of the expansion valve is reduced to the value
required to maintain the condition reached. Cooling can take place in single-zone operation (tandem operation)
or in two-zone operation. In single-zone operation (tandem operation), sensors Ry.1 have an effect on relay 1
and relay 2.
R4.1: Refrigerant temperature sensor (terminals Z21/22)
