LIST OF LEVEL 2 VARIABLES (Installer level)
VARIABLE
MEANING
VALUES
DEFAULT
nrC
Number of compressors (or solenoids or
systems)
1 = 1 system
2 = 2 system
2
nrE
Number of evaporators
1 = 1 evaporator
2 = 2 evaporators
2
Set
Single or double set-point setting
(ignored if nrC = 1)
1 = one setting only
2 = double setting
1
rot
Compressor rotation
(ignored if nrC = 1)
0 = compressor rotation
1 = fixed call
0
F3
Fan status with compressor off
0 = Fans running continuously
1 = Fans running only if compressor
is working
2 = fans disabled
1
F4
Fan pause during defrost
0 = Fans running during defrost
1 = Fans not working during defrost
1
F6
Evaporator fans activation for air recirculation.
The fans activate for a time defined by F7 if they
have not started working for the F6 time. If activation
time coincides with the defrosting time, end of
defrosting is awaited.
0
– 240 min
0 = (function not activated)
0 min
F7
Evaporator fans duration for air recirculation.
Fans working time for F6
0-30 min
10 min
dE1
Evaporator 1 sensor presence
Disabling the evaporator sensor causes defrosts
to occur cyclically with period
d0
or by real time
clock and terminate according to time
d31
0 = evaporator 1 sensor present
1 = evaporator 1 sensor absent
0
dE2
Evaporator 2 sensor presence
Disabling the evaporator sensor causes defrosts
to occur cyclically with period
d0
or by real time
clock and terminate according to time
d32
0 = evaporator 2 sensor present
1 = evaporator 2 sensor absent
0
d1
Defrost type
, cycle inversion (hot gas) or
elements
With 2 compressors and only 1 evaporator both
compressors are activated.
0 = heater
1 = hot gas
2 = hot gas with basin
3 = heater, with temperature control
0
d8
Post-defrost compressor start mode
.
Determines whether system compressor start is
possible or not if second is defrosting
0 = if an evaporator is still
defrosting the second system can
continue working
1 = compressors do not start until
all defrosts have been completed
0
Ad
Network address
for connection to TeleNET /
Modbus supervision system.
0 ÷ 31 if SEr=0
1 ÷ 247 if SEr=1
1
SEr
RS-485 communication protocol
0 = TeleNet Protocol
1 = Modbus-RTU Protocol
0
Bdr
Modbus baudrate
0 = 300 baud
1 = 600 baud
2 = 1200 baud
3 = 2400 baud
4 = 4800 baud
5 = 9600 baud
6 = 14400 baud
7 = 19200 baud
8 = 38400 baud
5
Prt
Modbus parity check
0 = none 1 = even parity
2 = odd parity
0
Ald
Minimum and maximum temperature
signalling
and alarm display delay.
0÷ 240 min
120 min
C1
Minimum time between shutdown and
subsequent switching on of the compressor
.
0 ÷ 15 min
0 min
