PAR RANGE DESCRIPTION
OA1 NON; AUX 1 output operation
LGT; NON : output disabled (always off).
0-1; LGT : output enabled for light control.
2CU; 0-1 : the relay contacts follow the on/standby state of controller.
2EU; 2CU : output programmed for the control of an auxiliary compressor.
ALO; 2EU : output enabled for the control of the electrical defrost of a second evaporator.
ALC ALO : contacts open when an alarm condition occurs.
ALC : contacts make when an alarm condition occurs.
2CD 0...120 sec Auxiliary compressor start delay. If OAx=2CU the auxiliary output is switched on with a delay of
2CD seconds after the main compressor has cut-in. Both compressors are turned off at the same
time.
OS1
-12.5..12.5° Probe T1 offset.
T2 NO/YES Probe T2 enabling (evaporator).
OS2 -12.5..12.5° Probe T2 offset.
T3 NON; Auxiliary probe T3 operation
NON : probe T3 not fitted.
DSP;
CND; DSP : temperature T3 to be displayed.
2EU CND : condenser temperature measurement.
2EU : second evaporator temperature measurement.
OS3 -12.5..12.5° Probe 3 offset.
AHM NON; Operation in case of high condenser alarm
ALR;
NON : high condenser alarm inhibited.
STP;
ALR : in case of alarm, "HC" flashes in the display and the buzzer is switched on.
STP : in addition to the alarm symbols displayed, the compressor is stopped and defrosts are
suspended.
AHT -50...110° Condensation temperature alarm (referred to T3 probe).
TLD 1...30 min Delay for minimum temperature (TLO) and maximum temperature (THI) logging.
TDS T1; Selects the temperature probe to be displayed.
1-2; T1 : probe T1
T3 1-2 : the AVG-weighted average between T1 and T2
T3 : probe T3
AVG 0...100% The relative weight of T2 on T1 (if TDS = 1-2)
Example 1: T1 = -5°, T2 = -20°, AVG = 100%. The displayed temperature will be -20° (T1 has no
effect)
Example 2: T1 = -5°, T2 = -20°, AVG = 60%. The displayed temperature will be -14.
SCL 1°C; Readout scale.
2°C; 1°C : measuring range -50...110°C (0.1°C resolution within -9.9 ÷ 19.9°C interval, 1°C outside)
°F 2°C : measuring range -50 ... 110°C
°F : measuring range -55 ... 180°F
SIM 0...100 Display slowdown.
ADR 1...255 TRL-002 address for PC communication.
NPR 0...1 Setup programmed.
STT 0...255 Setup traceability.
