The ECOLITE controller is equipped with a temperature
control, e.g. for a cold store. To measure the temperat-
ure, a BITZER NTC temperature sensor (10kΩ@25°C)
must be installed in the cold store and connected to the
electrical box of the condensing unit instead of the suc-
tion gas temperature sensor. During the cold store tem-
