emperature
regulation
0 to 255s
This value is used only when 
[CrE = Y] or [C
rE = EUP].
It is the
integral time for thermoregulation: high
values mean slower regulation.
0 (zero) = no integral action

ation
n(0); Y(1); EUP(2)
With [C
rE = Y] or [C
rE = EUP], the
regulation becomes PI, HY becomes a
band and int an integral time.
n = stand
ard regulation
Y = continuous regulation, to be used
only in centralized plants

LS -50 Minimum setpoint
[-67°F to SET]
[-55.0°C to SET]
Sets the minimum acceptable value for
th

t.
US 70 Maximum setpoint
[SET to 302°F]
[SET to 150.0°C]
Sets
the maximum acceptable value for
the setpoin

odS 0
Outputs activation
delay at start up
0 to 255mi
n
This function is enabled at the initial
startup of the devi
ce and inhibits any
output activation for the period of time
set in this parameter (AUX and Light
can work).
AC 0
Anti-short cycle
delay
0
to 60min
Interval between the solenoid valve
stop and the following restart.
CCt 0.0
Continuous cycle
duration
0.0 to 24h00m
in (144)
Compressor ON time during
continuous
cycle: Allows the length of
the continuous cycle to set: compressor
stays ON without interruption for the
CCt time. It can be used, for instance,
when the room is filled with new
products.
