DEFROST
REGULATION
Hy
Differential:
(0,1 ÷ 25,5°C / 1÷255 °F) Intervention differential for set point. Compressor Cut IN is
Set Point + differential (Hy). Compressor Cut OUT is when the temperature reaches the set point.
LS
Minimum set point:
(-100°C ÷ SET; [-148F ÷ SET): Sets the minimum value for the set point.
US
Maximum set point:
(SET÷150°C/ SET÷302°F). Set the maximum value for set point.
Ot
Thermostat probe calibration:
(-12.0÷12.0°C; -120÷120°F) allows to adjust possible offset of the
thermostat probe.
OdS Outputs activation delay at start up:
(0÷255min) This function is enabled at the initial start up of
the instrument and inhibits any output activation for the period of time set in the parameter.
AC
Anti-short cycle delay:
(0÷50 min) minimum interval between the compressor stop and the
following restart.
CCt Compressor ON time during continuous cycle:
(0.0÷24.0h; res. 10min) Allows to set the length of
the continuous cycle: compressor stays on without interruption for the Cct time. Can be used, for
instance, when the room is filled with new products.
CCS Set point for continuous cycle:
(-100÷150°C; -148°F ÷ 302°F) it sets the set point used during the
continuous cycle.
Con Compressor ON time with faulty probe:
(0÷255 min) time during which the compressor is active in
case of faulty thermostat probe. With COn=0 compressor is always OFF.
COF Compressor OFF time with faulty probe:
(0÷255 min) time during which the compressor is OFF in
case of faulty thermostat probe. With COF=0 compressor is always active.
CH
Type of action:
CL = cooling; Ht = heating.
CF
Temperature measurement unit
:
°C
=Celsius;
°F
=Fahrenheit. WARNING: When the measurement
unit is changed the SET point and the values of the parameters Hy, LS, US, Ot, ALU and ALL have to
be checked and modified if necessary).
rES Resolution (for °C):
(in = 1°C; dE = 0.1 °C) allows decimal point display.
dLy Display delay:
(0 ÷20.0m; risul. 10s) when the temperature increases, the display is updated of 1
°C/1°F after this time.
IdF
Interval between defrost cycles:
(0÷120h) Determines the time interval between the beginning of
two defrost cycles.
MdF (Maximum) length for defrost:
(0÷255min) When
P2P = n
, (not evaporator probe: timed defrost) it
sets the defrost duration, when
P2P = y
(defrost end based on temperature) it sets the maximum
length for defrost.
dFd Temperature displayed during defrost:
(rt = real temperature; it = temperature at defrost start;
SEt
= set point; dEF =
“dEF”
label)
dAd MAX display delay after defrost:
(0÷255min). Sets the maximum time between the end of defrost
and the restarting of the real room temperature display.
