This function is enabled after the
0 to 255 min
instrument power-on and delays the
activation of the outputs.
Delay between first compressor (CP1)
0 to 50 min
stop and the next restart.
Delay between second compressor
0 to 255 min
(CP2) stop and the next restart.
FUL=delayed respect to main onoff
FUL(0); HAF(1)
compressor; HAF=step activation logic,
par. HY1 is used.
n=compressor 1 is activated always as
n(0); Y(1)
first; Y= toggle compressor 1 and
compressor 2 activation.
Define the maximum running time for
0 to 255 min
onoff compressors.
CP1=only compressor CP1 is activated
during any defrost; CP2=only
CP1; CP2; 2CC
compressor CP1 is activated during any
defrost; 2CC=both compressors CP1 and
CP2 are activated during any defrost
Weighted coefficient for double probe
(P1 and P2) regulation
0 to 100
R=P1*(rtr/100)+P2*(1-rtr/100). If rtr=100:
only P1 value is used. If rtr=0: only P2
value is used.
When this interval ends, the Pull Down
0.0 to 23h50min
function is immediately stopped
During any Pull Down, the regulation
[-12.0°C to 12.0°C]
SETPOINT is moved to SET+CCS (in
[-21.6°F to 21.6°F]
normal mode) or to SET+HES+CCS (in
energy saving mode)
This is the upper limit used to
[0.0°C to 25.0°C]
automatically activate the Pull Down
[0.0°F to 45.0°F]
function
This is the upper limit used to
[0.0°C to 25.0°C]
automatically activate the Pull Down
[0.0°F to 45.0°F]
function in energy saving mode.
Interval with compressor output ON in
0 to 255 min
case of faulty regulation probe. With
Con=0 compressor output is always OFF
Interval with compressor output OFF in
0 to 255 min
case of faulty regulation probe. With
CoF=0 compressor output is always ON
