Siemens Superheat Controller CE1N3372en_02
Smart Infrastrucutre 2022-02-16
Following the initial power up, the controller automatically enters the configuration
mode. In this mode, the type of refrigerant is selected and the unit of temperature
°C or °F and pressure Bar or Psi determined.
Optionally, control of the cooling capacity can be configured.
To reconfigure the controller, refer to "Selection of operation mode" above.

1) The compressor of Circuit 1 is the default working unit and cannot be disabled. EIV feedback signal is
only available for Circuit 1.
2) Can be parameterized only if external or internal capacity control has been selected in the configura-
tion mode.
3) The range limit (RANGE) can be configured only if internal capacity control (application 3) and X4
have been selected.
If the wrong type of refrigerant is selected, the plant can be damaged!
