the condenser fan is on on condition that the compressor is on and is off when the temperature of the condenser drops below the temperature established with parameter F11 on condition that
the compressor is off
(31)
the compressor is switched off 10 sec after the activation of the input; if the input is activated during defrosting or when the evaporator fan is deactivated, the activation will not have any effect
on the compressor
(32)
the device stores the alarm once the time established in parameter i2 has expired; if parameter i2 is set at -1, the device will not store the alarm
(33)
if the parameter i5 i0 and parameter i15 are set at the same value, the effect will be caused by the activation of at least one of the inputs (until both inputs are deactivated)
(34)
make sure that the time established with parameter i7 is less than that established with parameter i9
(35)
to avoid damaging the unit connected to the instrument, set the parameter setting when the device is switched off
(36)
make sure that parameter u1 is not set at 1 when parameter u11 is set at 2 (and vice versa)
(37)
if parameter d8 is set at 3, the setting shall have no effect and the device shall operate as if the parameter were set at 0
(38)
if parameter d8 is set at 2 or 3, the setting shall have no effect and the device shall operate as if the parameter were set at 0; it is suggested to set parameter P4 at 3 (the evaporator
temperature probe shall be associated with defrosting and the evaporator 2 temperature probe shall be associated with defrosting 2)
(39)
it is suggested to set parameter P4 at 3 (the evaporator temperature probe shall be associated with the evaporator fan and the evaporator 2 temperature probe shall be associated with the
evaporator 2 fan)
(40)
if parameter u2 is set at 0, switching off the device may cause the room light and/or the auxiliary output to switch off (the next time the instrument is switched on the unit connected will remain
switched off); if parameter u2 is set at 1, switching off the device will not cause the room light or the auxiliary output to switch off (the next time the instrument is switched on the unit
connected will remain switched on)
(41)
the heating elements are switched on when the room temperature of the cabinet or the CPY temperature drops below the “work set-point + u7” and are switched off when the temperature rises
above the “work set-point + u7 + 2 °C/°F”
(42)
the switching on of the device shall switch on the application and the switching off of the device shall switch off the application
(43)
the parameter is in ten (for example, 1 = 10 steps, 10 = 100 steps, etc.)
(44)
the parameter differential is 2,0 bar g / PSI g
(45)
the models integrating the unipolar electronic expansion valves driver do not support the backup module for the valve closure in case of lack of power supply; it is suggested to set parameter u1
(or u11) to 11 and connect the digital output K5 (or K6) to a solenoid valve.
