Parameter Descriptions
Compressor (COn)
SET = Working Set Point. Temperature the system trys to maintain. Variable
between r1 and r2.
r0 = Differential. When primary probe temperature >= Set+r0 Compressor ON
When primary probe temperature <= Set Compressor OFF
r6 = Fan operation on regulation.
Off = Fan does not connect on regulation.
On = Fan is always connected on regulation.
Con = Fan linked to compressor start-up.
(Fan ON if allowed by the temperature set in F0)
F0 = Fan temperature limit.
Direct mode. Relay selected as FAN. Fan OFF on regulation when probe temperature
set in d12 is >= F0. Fan ON on regulation, when temperature is =< F0 - A0.
Reverse mode. Relay selected as FAI. Fan OFF on regulation when probe
temperature set in d12 is < F0. Fan ON on regulation, when temperature is >= F0 + A0.
F1 = Stop compressor and Fan if door opened (Circuit closure between input
terminal 5 and common terminal 4).
No = the fan and compressor do not stop on regulation and continuous cycle when
opening the door.
Yes = the fan and compressor stop on regulation and continuous cycle when opening
the door.
Con = the compressor stop but the fan do not stop on regulation and continuous
cycle when opening the door.
Fan = the fan stop but the compressor do not stop on regulation and continuous
cycle when opening the door.
c0 = Minimum compressor stop time. Minimum time since compressor stops until
it is starts again.
c1 = Continuous cycle time. Duration of a continuous cold cycle.
c2 = ON time of fault cycle, when ambient probe is broken
c3 = OFF time of fault cycle, when ambient probe is broken
c4 = Minimum time since compressor starts until it stops.
c5 = Minimum time since compressor starts until it starts again.
Defrost (dEF)
d0 = Cool / Heat mode (ST13). re = cool; In = heat
d0 = Type of defrosting (ST23, ST33)
re = defrosting without connecting the compressor.
in = defrosting by connecting the compressor.
d1 = End of defrosting temperature. When this temperature is reached the defrosting
will end.
d2 = Maximum defrosting time. The defrosting will stop when this time is reached. If
it is zero there will be no defrosting.
d3 = First hour defrosting of the day. From 00:00 hours the first defrosting is at d3
hours. Until this time no defrosting is performed.
d4 = Delay first defrosting.
Time to carry out the first defrosting if d3 = yes.
d5 = Display during the defrosting.
Off = the current temperature will be shown during defrosting.
On = the temperature at defrost beginning is frozen on display until the end of
defrosting and until the current temperature is equal or lower than the initial one, or
until d6 time elapses.
-d- = Label -d- is displayed during defrosting, until the end of defrosting and until the
current temperature is equal or lower than the initial one, or until d6 time elapses.
d6 = Display return limit. Maximum time before viewing the current temperature
again after defrosting.
d7 = Compressor drip time. Time since defrosting ends until the compressor can
be connected.
d8 = Interval between defrosting. Time between the start of a defrosting and the start
of the following one. If it is zero defrosting is not done automatically by time.
d9 = Fan operation during defrosting time. It determines if the fan is connected or
not during defrosting.
d10 = Fan drip time. Time since defrosting ends until fan can be connected.
d11 = Minimum Time duration defrosting. Once defrosting begins it stays at least
during this time
d12 = Fan & defrosting control probe.
sd1 = primary probe
sd2 = defrosting probe
sd3 = product probe
d14 = Units to count the defrosting cycle.
rt = according to the working time of the controller
ct = according to the working time of the compressor
