If room temperature control is set, the solenoid valve of
the liquid line is controlled according to the temperat-
ure. The capacity of the ECOLITE condensing unit con-
tinues to be controlled according to the suction pres-
sure. The suction pressure set point must therefore be
set to a sufficiently low value.
The external cold store temperature sensor is connec-
ted to the terminal strip X10 terminals 7 and 8. In deliv-
ery condition of the condensing unit, the suction gas
temperature sensor is connected to these terminals.
This sensor must be disconnected when the cold store
temperature sensor is connected and is therefore not
operational when the cold store temperature control is
active. BITZER cold store temperature sensors (NTC,
10kΩ@25°C) should be used. Other sensors are not
supported.
