Superheat controller and stepper valve driver, Type EKE 1A, 1B, 1C, 1D
6.2.3 O setting Superheat, Temperature and OD Via External signal
Temperature and superheat references can be displaced in positive or negative direction using a current signal
(EKE1C only), voltage signal or via Modbus.

Description
Ext. reference
This setting determines how large the o set is when input signal is at min.
This setting determines how large the o set is when input signal is at max.
De ne how the external reference signal is used
0 = V->SH: Displacement of SH reference given by External voltage signal.
1 = V->Temp: Displacement of temperature given External voltage signal.
