7.6 CONFIGURING THE ANTIFREEZE CONDITIONS
1. Indicates to which compressor the displayed data refers (U:1 = Master; U:2 =
Slave 1; U:3 = Slave 2; U:4 = Slave 3)
2. This value is used to choose whether to activate the cyclic fan activation func-
tion on the basis of the outside temperature. This prevents the accumulation
of snow in the fans, and therefore the risk of ice formation, if the outside tem-
perature falls very low (YES = cyclic fan activation enabled; NO = cyclic fan
activation not enabled)
3. Indicates the outside air temperature below which cyclic fan activation is
launched (if cyclic fan activation is enabled)
4. Indicates the time gap between two consecutive fan switch-on operations (if
cyclic fan activation is enabled)
5. Indicates the duration of the fan cycle (if cyclic fan activation is enabled)
6. Indicates the temperature read on the evaporator outlet gas side, below which
the evaporator gas side anti-freeze alarm activates
7. Indicates the differential to be applied to the evaporator outlet gas side tem-
perature to exit the relative anti-freeze alarm
8. Setpoint antifreeze condensator: not used
9. Differential antifreeze condensator: not used
10. Indicates the temperature value for thermostat control (evaporator inlet or
outlet), below which the antifreeze alarm is activated
11. Indicates the value of the differential, to be added to the inlet temperature
on the recovery tank (if installed), for quitting the recovery antifreeze alarm
condition
12. Indicates the heat exchanger water outlet temperature value, below which the
anti-freeze resistance is activated
13. Indicates the heat exchanger water outlet temperature value, above which the
anti-freeze resistance is deactivated
14. This value allows deciding whether to activate the pump with the anti-freeze
resistance (YES= pump on with anti-freeze resistance; NO = pump not on with
anti-freeze resistance)
7.7 PUMP AND COMPRESSOR FUNCTIONING LOG
1. Indicates to which compressor the displayed data refers (U:1 = Master; U:2 =
Slave 1; U:3 = Slave 2; U:4 = Slave 3)
2. Indicates the number of hours during which the evaporator pump has been
operated
3. Not used
4. Indicates the number of hours during which the currently selected compressor
has been operated
5. Not used
6. Not used
7. Indicates the number of hours beyond which a maintenance alarm is gener-
ated for the currently selected compressor; this number is then multiplied by
1000, so if you want to set 2000 hours as threshold, enter 2 as value
8. Allows resetting the current hours of work counted for the currently selected
compressor
9. Indicates the number of hours beyond which a maintenance alarm is generat-
ed for the evaporator pump; this number is then multiplied by 1000, so if you
want to set 2000 hours as threshold, enter 2 as value
10. Allows resetting the current hours of work counted for the pump on the
evaporator
7.8 DCP SETTINGS OR INVERTER FANS
1. Indicates to which compressor the displayed data refers (U:1 = Master; U:2 =
Slave 1; U:3 = Slave 2; U:4 = Slave 3)
2. This value allows deciding whether to activate the night-time silenced func-
tioning; this function is not available on silenced units. Also, for it to be activat-
ed, the unit must have inverter fans or be equipped with DCP; (YES = function
active; NO = function not active)
3. Indicates the value in Volts to be assigned to the maximum fan speed during
the night-time silencing function. This value can range from 0 to 10V, where
10V is the maximum speed available for the fans
4. Indicates the value in Volts to be assigned to the maximum fan speed (during
the freecooling functioning mode) during the night-time silencing function.
This value can range from 0 to 10V, where 10V is the maximum speed available
for the fans
5. Heat: Not used
6. Indicates the value in Volts to be assigned to the maximum fan speed during
the normal freecooling functioning. This value can range from 0 to 10V, where
10V is the maximum speed available for the fans
7. Indicates the value in Volts to be assigned to the maximum fan speed during
the normal functioning. This value can range from 0 to 10V, where 10V is the
maximum speed available for the fans
8. Indicates the value in Volts to be assigned to the minimum fan speed during
the normal functioning. This value can range from 0 to 10V, where 0V is the
minimum speed available for the fans
9. Indicates the time for which to maintain the peak on fan start-up (during the
normal functioning of the fans)
7.9 ENABLINGS FREECOOLING GLICOLE FREE
— Indicates to which compressor the displayed data refers (U:1 = Master; U:2 =
Slave 1; U:3 = Slave 2; U:4 = Slave 3)
— This value allows deciding whether to activate or deactivate the freecooling
mode, for the models provided with it (YES =freecooling active; NO = freecool-
ing not active)
— This value allows deciding whether to activate or deactivate the glycol free free-
cooling mode, for the models provided with it (YES =freecooling active; NO =
freecooling not active)
