If room temperature control is set, the solenoid valve of
the liquid line is controlled according to the measured
room temperature. The capacity of the ECOLITE con-
densing unit continues to be controlled according to the
suction pressure. 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 the
state of delivery 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.

Refrigerant type in the system
0 = R404A, 4 = R134a, 5 = R407C, 8 = R507A, 9 = R407A, 11 = R407F,
12 = R450A, 14 = R448A, 15 = R513A, 16 = R449A
Ex-factory setting: 0= R404A
ECOLITE system configuration
0 = no CR II capacity regulator available
1 = 2-cylinder compressor with CR II capacity regulator available
2 = 4-cylinder compressor with 1 CR II capacity regulator available
3 = 4-cylinder compressor with 2 CR II capacity regulators available
Ex-factory setting: same as state of delivery of the condensing unit
ECOLITE control function
2 = room temperature control
3 = reserved
4 = suction pressure control
Ex-factory setting: 4 = suction pressure control
ECOLITE system of units
0 = Europe (bar / °C) metric
1 = America (PSI / °F) IP
Ex-factory setting: 0 = Europe (bar / °C) metric
In the menu F2+F4⇒PASS, enter the value "2".
