Remarks
•
/1 Value to be shown on display
0 = Thermostat control temperature, Alignment factor /C will
only work with this temperature display
1 = Air in temperature
2 = Air out temperature
3 = Alarm temperature
4 = Defrost termination temperature
5 = Coil in temperature
6 = Coil out temperature
7 = Superheat
8 = Valve opening
9 = Defrost status
10 = not used
11 = not used
•
/2 No alarms
0 = alarms will be shown on display
1 = alarms will not be shown on display
•
/5 Temperature unit for display
0 = °C
1 = °F
•
/6 Display with decimal point
0 = yes, in the range from –19.9 to 19.9
1 = no
•
/7 Display during defrost
0 = “df”
1 = “df” + defrost termination temperature
2 = “df” + control temperature
•
r0 Door contact function
Contact closed or nviDoor = ST_ON
Value = C Alarm + Timer + Action
Cooling 0 = cooling
1 = no cooling
Alarm 0 = temperature alarm on, door alarm
2 = temperature alarm off, door alarm off
Timer 0 = Timer not started
4 = Timer started
Action when timer expired
0 = temperature alarm on, door alarm
8 = temperature alarm on, door alarm,
cooling restart if “Cooling = 1”
•
r4 Thermostat mode
0 = off, no thermostat function, continues cooling
air in and air out sensor monitoring off, no temp. alarms
generated
1 = cooling, deadband control
cut in = set-point + difference
cut out = set-point
2 = cooling, modulating thermostat
cut in = set-point
cut out = set-point – difference /2
3 = heating, deadband control
cut in = set-point – difference
cut out = set-point
4 = on, external control by nviValve
air in and air out sensor monitoring off, temp. alarms
will be generated

•
d0 Defrost mode
0 = natural defrost, defrost heater not activated
pulsed defrost not possible, synchronization by bindings
1 = forced defrost, defrost heater activated, pulsed
defrost possible, synchronization by bindings
2 = forced defrost, defrost heater activated, pulsed
defrost possible, synchronization by nviStartUp
•
d1 Termination by temperature / time
0 = termination by temperature, termination by time
will generate an alarm
1 = termination by time, termination by temperature
will generate an alarm
2 = first, what ever comes first time or temperature,
no alarm
3 = last, by time and temperature, no alarm
•
d2 Defrost termination sensor
0 = defrost termination sensor
1 = air out sensor
•
d3 Pulsed defrost
0 = off, no pulsed defrost, heaters switched off at
defrost termination temperature dt or max. time
dP whatever is selected
1 = on, pulsed defrost, dd and dH in use, heaters are
switched off at dH and switched on again at
dH – dd
•
d6 Pump down delay
The compressor will run during pump down delay while
the valve is closed
•
d8 Injection delay
The valve is open during injection delay while the
compressor is not running
•
d9 Demand defrost mode
0 = demand defrost off
1 = on
2 = on + defrost if no demand defrost within dI
•
F1 Start up sequence after defrost
0 = on
1 = delayed by time Fd, error on temperature
2 = by temperature Ft, error on time
3 = first, whatever comes first time or temperature,
no alarm
4= last, time and temperature must come, no alarm
•
F2 Fan status during no cooling
0 = on
1 = off
2 = delayed by F4
