7 SIGNALS
7.1 Signals
LED MEANING
Compressor LED
if it is lighted, the compressor will be ON
if it flashes, a compressor delay will be running (look at the parameters
C0, C1, C2, C4, n1 and n4)
Defrost LED
if it is lighted, the defrost output will be activated
if it flashes:
• a defrost delay will be running (look at the parameters C0, C1, C2, C4,
n1 and n4)
• the dripping will be running (look at the parameter d7)
• the freezing fluid heating will be running (look at the parameter dP)
(16) do not set more instruments as master
(17) the time between the master implements a control and the slave implements the same control is “n1 x n4”
(18) except the control turning ON and OFF; it will immediately be implemented
(19) if among the remote controls the slave has to implement there is the defrost activation, the parameter d5 will set a time you will have to add to the one you have set with the
parameters n1 and n4 (the slave will implement the control even if the conditions will not allow the master of activating the defrost); if the master is in the STAND-BY mode and
among the remote controls the slave has to implement there is not the turning ON and OFF, the slave will work with the local settings.
11 ELECTRICAL CONNECTION
11.1 Electrical connection
(20) short-circuit terminals 1 and 5 and/or 1 and 7 if you do not use the lock input and/or the compressor thermal protection
(21) the position of the probe for compressor thermal protection could compromise the insulation between low voltage and high voltage parts.
nA 0 15 --- 0 remote control the slave has to implement (0 = no controls, 1 and 9 = compressor status,
2 and 10 = defrost activation, 3 and 11 = compressor status and defrost activation,
4 and 12 = turning ON and OFF, 5 and 13 = compressor status and turning ON and OFF,
6 and 14 = defrost activation and turning ON and OFF, 7 and 15 = compressor status,
defrost activation and turning ON and OFF, 8 = reserved)

(5) the unit of measure depends on the parameter /8
(6) damin = 10 minutes
(7) unless the evaporator temperature is below the defrost end temperature you have set with the parameter d2, the defrost will not be activated
(8) if the time the compressor is ON is lower than 30 s, the compressor will never be ON; if the cabinet probe failure takes place during a compressor delay, the compressor will be
forced OFF for 1 min; the parameter C1 sets the minimum delay between the end of the cabinet probe failure and the following activation of the compressor (if the parameter
C1 has value 0, the compressor will be forced off for 2 min)
(9) if at the moment of the defrost activation the cabinet temperature is below the value “working setpoint + r0” , the instrument will not show temperatures above that value; if
at the moment of the defrost activation the cabinet temperature is above the value “working setpoint + r0” , the instrument will not show the increases of the temperature (if
the increase takes place below the value “working setpoint + r0” , look at the previous case); the instrument restores the normal operation once the after dripping evaporator
fan delay ends and the cabinet temperature falls below the freeze temperature
(10) if at the moment of the defrost activation the compressor is ON since a time lower than the one you have set with the parameter, the compressor will be forced ON for a time
such as to finish the time you have set with the parameter
(11) if the lower temperature alarm takes place during the count of the delay, this last will be cleared
(12) if the temperature alarm does not disappear at the end of the times you have set with the parameters A3 and AA, it will further be excluded for the time you have set with the
parameter A6; if the temperature alarm takes place during the defrost and does not disappear at the end of the time you have set with the parameter A7, it will further be
excluded for the time you have set with the parameter A6; if the temperature alarm takes place during the multifunction input activation, it will be excluded for the time
"A5 + A6" since the input activation or for the time you have set with the parameter A6 since the input deactivation
(13) the evaporator fan stop temperature is “cabinet temperature - F1” ; you always have to consider the parameter F1 with positive sign
(14) the instrument will automatically verify the maximum value of the parameter; it always has to be lower than the value you have set with the parameter i4
(15) when there is 1 min to the end of the time you have set with the parameter, the cabinet light will be turned OFF just for 1 s; press during the time you have set with the
parameter to turn the cabinet light ON and to exclude the function, press again before the end of the time you have set with the parameter to recover the function
(if the remaining time of the parameter is higher than 1 min, the time will be forced at 1 min and the cabinet light will be turned OFF just for 1 s)

Cabinet light LED
if it is lighted, the cabinet light will be ON
if it flashes, the multifunction input will be active (look at the parameters
i0, i1 and i7)
Lock input/thermal protection LED
if it is lighted, there will have been a number of lock input/thermal pro-
tection alarms such as to give the lock of the instrument (turn the instru-
ment OFF and turn it ON again, look at the parameters i2, i3, i4 and i5)
if it flashes, the lock input/thermal protection will be active (look at the
parameters i2, i3, i4 and i5)
ON STAND-BY LED
if it is lighted, the instrument will be in the STAND-BY mode
if it flashes, the instrument will be set as slave but it will not be author-
ized to implement the remote controls coming from the master (look at
the parameter n3)
if it flashes every two seconds, the instrument will be set as slave and
among the remote controls, coming from the master, the slave has to
implement, there will be the turning ON and OFF (look at the param-
eter nA)
INDICAT.
the instrument will be set as slave and among the remote controls, com-
ing from the master, the slave has to implement, there will be the com-
pressor status (look at the parameter nA).
If you have to show the cabinet temperature, press
the instrument will be set as slave, among the remote controls, coming
every 2 s
from the master, the slave has to implement, there will be the compres-
sor status but there will not be the turning ON and OFF, both the master
and the slave will be in the STAND-BY mode (look at the parameter nA).
If the master is in the STAND-BY mode and the slave is ON, the indica-
tion will be showed alternated with the cabinet temperature
