dIXEL

COF2 Compressor2 OFF time with faulty probe2: (0÷255 min) time during which the compressor is off in case of faulty thermostat probe. With

COF=0 compressor2 is always active.

CH2

Kind of action for section 2: CL = cooling; Ht = heating

DISPLAY

Temperature measurement unit: °C = Celsius; °F = Fahrenheit. When the measurement unit is changed the SET point and the values of

some parameters have to be modified.

rES

Resolution (for °C): (in = 1°C; de = 0,1°C) allows decimal point display. dE = 0,1°C; in = 1 °C

Lod1

Bottom display visualization (section 1): select which probe is displayed by the instrument in the bottom display: P1 = Thermostat 1

probe; P2 = Evaporator 1 probe; P3 = Thermostat2 probe; P4 = Evaporator 2 probe

Lod2

Upper display visualization (section 2): select which probe is displayed by the instrument in the upper display: P1 = Thermostat 1 probe;

P2 = Evaporator 1 probe; P3 = Thermostat2 probe; P4 = Evaporator 2 probe

DEFROST

dFS

Relation between defrosts.4 relation between the 2 sections of the controller are available, to manage different kinds of applications: in =

independent defrosts; StS = same defrost start, synchronised defrost end; St = same defrost start, independent defrost end; SE = sequential

defrost;

tdF1

Defrost type, section 1: rE = electrical heater (Compressor OFF); in = hot gas (Compressor and defrost relays ON)

EdF1

Defrost mode, section 1: in = interval mode. The defrost starts when the time "IdF1" is expired.

Sd = Smartdefrost mode. The time IdF (interval between defrosts) is increased only when the compressor is running (even non

consecutively);

rtc (only for instruments with RTC): beginning of defrost cycles is set by the L1d1÷L1d6 parameters during the working days and

S1d1÷S1d6 during the holidays

Set point for SMARTDEFROST, section 1: (-30

defrosts) in SMARTDEFROST mode.

dtE1

Defrost termination temperature, section 1: (-50,0÷110,0°C; -58÷230°F) (Enabled only when the evaporator probe is present) sets the

temperature measured by the evaporator probe which causes the end of defrost.

IdF1

Interval between defrosts, section 1: (1÷120h) Determines the time interval between the beginning of two defrost cycles.

MdF1 (Maximum) duration of defrost, section 1: (0÷255 min) When P2P = no, no evaporator probe, it sets the defrost duration, when P2P =

yES, defrost end based on temperature, it sets the maximum length for defrost.

tPF1

Pre-defrost time: (0÷30min) The compressor is activated for this time before a hot gas defrost.

Fdt1

Drain down time, section 1: (0÷60 min.) time interval between reaching defrost termination temperature and the restoring of the control's

normal operation. This time allows the evaporator to eliminate water drops that might have formed due to defrost.

dPo1

First defrost after start-up, section 1: y = Immediately; n = after the IdF time

Defrost type, section 2: rE = electrical heater (Compressor OFF); in = hot gas (Compressor and defrost relays ON)

tdF2

EdF2

Defrost mode, section 2: in = interval mode. The defrost starts when the time "IdF1" is expired.

Sd = Smartdefrost mode. The time IdF (interval between defrosts) is increased only when the compressor is running (even non

consecutively);

rtc (only for instruments with RTC): beginning of defrost cycles is set by the L1d1÷L1d6 parameters during the working days and

S1d1÷S1d6 during the holidays

SdF2

Set point for SMARTDEFROST, section 2: (-30

between defrosts) in SMARTDEFROST mode.

dtE2

Defrost termination temperature, section 2: (-50,0÷110,0°C; -58÷230°F) (Enabled only when the evaporator probe is present) sets the

temperature measured by the evaporator probe which causes the end of defrost.

IdF2

Interval between defrosts, section 2: (1÷120h) Determines the time interval between the beginning of two defrost cycles.

MdF2 (Maximum) duration of defrost, section 2: (0÷255 min) it sets the defrost duration.

tPF2

Pre-defrost time: (0÷30min) The compressor 2 is activated for this time before a hot gas defrost.

Fdt2

Drain down time, section 2: (0÷60 min.) time interval between reaching defrost termination temperature and the restoring of the control's

normal operation. This time allows the evaporator to eliminate water drops that might have formed due to defrost.

dFd

Display during defrost: rt = real temperature; it = temperature reading at the defrost start; Set = set point; dEF = "dEF" label; dEG = "dEG"

label;

dAd

Defrost display time out: (0

display.

dSd

Start defrost delay : ( 0÷99min) This is useful when different defrost start times are necessary to avoid overloading the plant.

FANS – Section 1

FnC1 Fan operating mode, section 1: C-n = running with the compressor1, OFF during the defrost; C-y = running with the compressor1, ON

during the defrost; O-n = continuous mode, OFF during the defrost; O-y = continuous mode, ON during the defrost;

Fnd1

Fan delay after defrost, section 1: (0÷255 min) The time interval between the defrost end and evaporator 1 fans start.

FSt1

Fan stop temperature, section 1: (-50÷110°C; -58÷230°F) setting of temperature, detected by evaporator probe, above which the fan is

always OFF.

FAP1 Probe selection for fans management, section 1: nP = no probe: fan follows the setting of FnC1 parameter; P1 = thermostat 1 probe; P2

= evaporator 1probe; P3 = thermostat 2 probe; P4 = evaporator 2probe;
