Dty
Defrosting type (
El
=Electrical defrost,
I
n
= hot gas defrost )
Dit
Defrosting interval
Dtl
Defrosting time limit
Dst
Defrosting temperature. If evaporator temperature is higher than this value, defrosting is disabled.
Dpo
Defrosting after power on (
y
=Defrosting begins when power is on,
n
=Defrosting doesn’t begin when power is on)
Ddp
Delay time for defrosting after power is on
Ddl
Locking of temperature indication during defrosting. (
n
= temperature is displayed during defrosting,
y
= Displayed value do not changes during Defrosting process.)
Ddt
Drainage time
Daa
Time interval required for alarm activation after completing defrosting
Ddc
Compressor with delay time at the selection of hot gas defrosting (
y
= Yes,
n
= No,
Note: Delay time is adjusted by using
CPO
,
CSB
and
CFS
parameters)
Dpr
The display of evaporator temperature
Dtb
Defrosting period time base (
hr
= Hour, minute
Sc
=Minute,second)
Adi
Switch hysteresis for alarm
Alr
Limit for low alarm level (If temperature falls down setpoint by this value, buzzer starts ringing)
Ahr
Limit for upper alarm level (If temperature exceeds setpoint by this value, buzzer starts ringing)
Apd
Time delay required for alarm to become active after power is on
Frt
Fan is controlled depending on temperature.
Fst
If evaporator temperature is above this parameter, fan stops
Fdi
Switch hysteresis for fan
Fco
Does fan stop when compressor stops? (
off
= Yes,
on
= No)
Fdo
Does fan stop during defrosting? (
off
= Yes,
on
= No)
Fdt
The time period of stopping fan after drainage.
