Table 45: Advanced → Advanced injection control
Function Description
Superheat ctrl. Select how to control the superheat of the evapora-
mode A tor. At adaptive control the superheat reference is
adapted automatically to give the best utilization of
the evaporator surface. At load based control the su-
perheat reference is increased at high loads
Superheat close A Minimum superheat limit where the valve is closing
AFidentForce A Expert setting - contact Danfoss for further informa-
tion
Superheat Kp min. A Min limit for amplification factor of the PI controller
adjusting the valve opening degree (expert setting)
Superheat Kp max. Max limit for amplification factor of the PI controller
A adjusting the valve opening degree (expert setting)
Superheat Tn A Integration time of the PI controller adjusting the
valve opening degree (expert setting)
Te feedback gain A Gain factor for feedback of evaporating temperature
signal Te to the PI controller controlling the superheat
(expert setting)
Kp MTR control A Amplification factor for modulating temperature con-
trol (Expert setting)
Tn MTR control A Integration time for modulating temperature control
(Expert setting)
AFident A Expert readout - contact Danfoss for further informa-
tion
