HEATING  (OSH<0):

  second compressor  cut IN is 

OSS-OAH

. Second compressor cut out is when the 

temperature 

OSS

.

  

OSi Probe selection for the second compressor:  rP

=thermostat probe; 

EP

=evaporator probe; 

tiM

=cycle 

count down; 

i1P

=insert probe 1; 

i2P

=insert probe 2; 

i3P

=insert probe 3.

 

DEFROST 

tdF Defrost type (not present in the XB350C):

 

rE

=electrical heater; 

in

=hot gas. 

idF  Interval between defrost cycles:

 (0.1 to 24h00min, res. 10 min) determines the time interval between 

the beginnings of two defrost cycles. 

dtE Defrost termination temperature:

 (-50 to 50; res. 1°C or 1°F) sets the temperature measured by the 

evaporator probe, which terminates the defrost. Used only if 

EPP=YES

MdF Maximum length for defrost:

 (0 to 255 min) when 

EPP=no

 (timed defrost) it sets the defrost duration, 

when 

EPP=YES

  (defrost termination based on temperature) it sets the maximum length for defrost. If 

MdF=0

 the defrost is disabled. 

dFd  Temperature displayed during defrost:

  (rt;  it;  SEt;  dEF) 

rt

=real temperature; 

it

=temperature at the 

start of defrost; 

SEt

=set point; 

dEF

=“dEF” message. 

Fdt Drip time:

  (0  to  60 min) time  intervals between reaching defrost  termination temperature and the 

restoring of the controllers' normal operation. This time allows the evaporator to eliminate water drops 
that might have formed during defrost. 

dAd Defrost display time out:

 (0 to 120 min) sets the maximum time between the end of defrost and 

the restarting of the real room temperature display.

 

FANS 

FnC Fans operating mode during the holding phase:

 

o-n

=continuous mode, OFF during defrost; 

C1n

=runs in parallel with the first compressor, OFF during defrost;  

C2n

=runs in parallel with the second compressor, OFF during defrost;  

Cn

=runs in parallel with compressors, OFF during defrost;  

o-Y

=continuous mode, on during defrost; 

C1y

=runs in parallel with the first compressor, on during defrost;  

C2y

=runs in parallel with the second compressor, on during defrost;  

Cy

=runs in parallel with compressors, on during defrost;  

FSt Fan stop temperature:

  (-50  to  50,  res. 1°C  or  1°F)  it used only if the 

EPP=YES

.  If the temperature, 

detected by the evaporator probe is above FSt fans are stopped. It serves to avoid blowing warm air in 
the room. 

AFH Differential for the stop temperature and for the alarm: 

(0.1 to 25.0°C, res. 0.1°C or 1°F) fans carry 

on working

 

when the temperature reaches the 

FSt-AFH

  value, the temperature alarm recovers when 

the temperature is 

AFH

 degrees below the alarm set. 

Fnd Fan delay after defrost:

 (0 to 255 min) the time intervals between ends of defrost and evaporator fans 

start. 

TEMPERATURE ALARMS 

ALU MAXIMUM temperature alarm (it is used only during the holding phase):

 (1.0 to 50.0, res. 0.1°C or 

1°F)  when the 

SET+ALU

  temperature is reached the  alarm is enabled, (possibly after the 

ALd

  delay 

time). 

ALL Minimum temperature alarm (it is used only during the holding phase):

 (1.0 to 50.0, res. 0.1°C or 

1°F)  when the 

SET-ALL

  temperature is reached the alarm is enabled, (possibly after the 

ALd

  delay 

time). 

ALd Temperature alarm delay (it is used only during the holding phase):

  (0  to  255 min) time interval 

between the detection of an alarm condition and alarm signalling. 

EdA Temperature alarm delay at the end of a defrost (it is used only during the holding phase): 

(0 to 

255 min) time interval between the detection of the temperature alarm condition at the end of defrost 
and alarm signalling. 

tbA Silencing alarm relay: Y

=silencing buzzer and alarm relay; 

n

=only buzzer silencing. 

CYCLE LOG 

tCy 

Duration of the last cycle (read only). 

tP1 

Duration of first phase of the last cycle (read only). 

tP2 

Duration of second phase of the last cycle (read only).
