10.3 Parameter description

10.3.1 Regulation
Label Description
HY Intervention differential for set point:
Compressor Cut IN is Set Point Plus Differential (HY).
Compressor Cut OUT is when the temperature reaches the set point.
LS Minimum set point:
Sets the minimum acceptable value for the set point.
US Maximum set point:
Sets the maximum acceptable value for set point.
ot Thermostat probe calibration: allows to adjust the possible offset of the
thermostat probe.
P2P Evaporator probe presence:
n = not present: time stops the defrost cycle;
y = present: temperature stops the defrost cycle.
oE Evaporator probe calibration:
Allows to adjust possible offset of the evaporator probe.
odS Outputs activation delay at start up:
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.
db Dead band (= neutral zone); allows the system to control the cell tempera-
ture to higher or lower temeratures compared to the set temperature. To
be used in case of heating kit.
n = neutral zone disabled; cooling only
y = neutral zone enabled; heating kit installed
AC Anti-short cycle delay: minimum interval between the compressor stop and
the following restart.
CCt Compressor ON time during continuous cycle:
Allows to set the length of the continuous cycle: compressor stays on with-
out interruption for the CCt time. Can be used, for instance, when the room
is filled with new products.
CCS Set point for continuous cycle: it sets the set point used during the continu-
ous cycle.
Con Compressor ON time with faulty probe: time during which the compressor
is active in case of faulty thermostat probe.
With Con = 0 the compressor is always OFF.
CoF Compressor OFF time with faulty probe: time during which the compressor
is OFF in case of faulty thermostat probe.
With COF = 0 the compressor is always active.
10.3.2 Display
Label Description
CF Temperature measurement unit:
°C = Celsius; °F = Fahrenheit.
ATTENTION
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 Display resolution (for °C only):
in = 1 °C;
dE = 0.1 °C; allows decimal point display.
