9 Parameters List
REGULATION
rtC Access to CLOCK submenu (if present)
EEU Access to EEV submenu (only XM679K);
Hy
Differential: (0.1 to 25.5°C; 1 to 45°F) This is the intervention differential for setpoint, this value is always
positive. Solenoid valve Cut IN is Setpoint Plus Differential (Hy). Solenoid valve Cut OUT is when the
temperature reaches the setpoint.
Int
Integral time for room temperature regulation (Only XM679K): (0 to 255 s) This is the integral time for room
temperature PI regulator. 0= no integral action.
CrE
Continuous regulation activation (Only XM679K): (n to Y) n= standard regulation; Y= continuous
regulation. Use it only in centralized plants;
LS Minimum setpoint limit: (-55.0°C to SET; -67°F to SET) Sets the minimum acceptable value for the setpoint.
US Maximum setpoint limit: (SET to 150°C; SET to 302°F) Set the maximum acceptable value for setpoint.
OdS
Outputs activation delay at start up: (0 to 255 min) This function is enabled at the initial start up of the device
and inhibits any output activation for the time set in the parameter. (AUX and Light can work)
AC Anti-short cycle delay: (0 to 60 min) The interval between the solenoid valve stop and the following restart.
CCt
Compressor ON time during continuous cycle: (0.0 to 24.0h; resolution 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
Setpoint for continuous cycle: (-55 to 150°C / -67 to 302°F) it sets the setpoint used during the continuous
cycle.
Con
Solenoid valve ON time with faulty probe: (0 to 255 min) The time during which the solenoid valve is active
in case of faulty thermostat probe. With COn=0 solenoid valve is always OFF.
CoF
Solenoid valve OFF time with faulty probe: (0 to 255 min) time during which the solenoid valve is off in case
of faulty thermostat probe. With COF=0 solenoid valve is always active
DISPLAY
CF
Temperature measurement unit: °C = Celsius; °F = Fahrenheit. CAUTION! When the measurement unit is
changed the parameters with temperature values have to be checked.
PrU
Pressure mode: (rEL or AbS) it defines the mode to use the pressure. CAUTION! the setting of PrU is used
for all the pressure parameters. If PrU = rEL all pressure parameters are in relative pressure unit, if PrU =
AbS all pressure parameters are in absolute pressure unit. (Only XM679K)
PMU
Pressure measurement unit: (bAr - PSI - MPA) it selects the pressure measurement units. MPA= the value of
pressure measured by kPA*10. (Only XM679K)
PMd
Way of displaying pressure: (tEM - PrE) it permits showing the value measured by pressure probe with tEM=
temperature or by PrE= pressure; (Only XM679K)
rES Resolution (for °C): (in = 1°C; dE = 0.1 °C) allows decimal point display;
Lod
device display: (nP; P1; P2, P3, P4, P5, P6, tEr, dEF) it selects which probe is displayed by the device. P1,
P2, P3, P4, P5, P6, tEr= virtual probe for thermostat, dEF= virtual probe for defrost.
