Refrigerant setting
Before refrigeration can be started, the refrigerant must be defined. You can select the
following refrigerants:
1=R12. 2=R22. 3=R134a. 4=R502. 5=R717. 6=R13. 7=R13b1. 8=R23. 9=R500.
10=R503. 11=R114. 12=R142b. 13=User defined. 14=R32. 15=R227. 16=R401A.
17=R507. 18=R402A. 19=R404A. 20=R407C. 21=R407A. 22=R407B. 23=R410A.
24=R170. 25=R290. 26=R600. 27=R600a. 28=R744. 29=R1270. 30=R417A.
31=R422A. 32=R413A. 33=R422D. 34=R427A. 35=R438A
(Warning: Wrong selection of refrigerant may cause damage to the compressor).
Service
A number of controller values can be printed for use in a service situation
Read valve's actuator temperature (TQ)
Read reference for valve's actuator temperature (TQ)
Read value of external current signal (AIA)
Read value of transmitted current signal
Read status of input DI (start/stop input)
Read the ongoing cutin time for the thermostat or the duration of the last completed
cutin
Read the temperature at the S2 sensor
Read superheat
Read the control's actual superheat reference
Read the valve's opening degree
Read evaporating pressure
Read evaporating temperature
Read the temperature at the S3 sensor
Read control reference
(Set setpoint + any contribution from external signal)
Read value of current signal from pressure transmitter (AIB)
Operating status
The controller's operating status can be called forth by a brief (1s) activation of the
upper button. If a status code exists it will be shown. (Status codes have lower priority
than alarm codes. This means that status codes cannot be seen if there is an active
alarm code.
The individual status codes have the following meanings:
S10: Refrigeration stopped by the internal or external start/ stop.
S11: Thermostat is cutout
