if parameter r12 is set to 0:
-
a compressor will be switched on when the room temperature or CPT temperature is above the "working set-point + r0/2" and another when the temperature is above the "working
set-point + r0"
-
a compressor will be switched off when the room temperature or CPT temperature falls below the "working set-point + r0/2" and another when the temperature is below the
working set-point
if parameter r12 is set to 1:
-
a compressor will be switched on when the room temperature or CPT temperature is above the working set-point and another when the temperature is above the "working set-point
+ r0/2"
-
a compressor will be switched off when the room temperature or CPT temperature falls below the "working set-point + r0/2" and another when the temperature is below the
"working set-point - r0/2"
the choice of which compressor to switch on/off depends on parameters C12 and C13
(8)
the parameter has effect even after an interruption in the power supply that occurs while the device is switched on
(9)
the time established with the parameter is counted even when the device is switched off
(10)
if parameter C1 is set at 0, the delay after the end of the room temperature/inlet air proble error will be 2 min
(11)
the parameter differential is 2,0 °C/4 °F
(12)
if when the device is switched on, the condenser temperature is already above that established in parameter C7, then parameter C8 will not have effect
(13)
the device memorises the defrosting interval count every 30 minutes; the setting of parameters d0 and d26 has effect from the conclusion of the previous defrosting interval or the activation of
defrosting in manual mode
(14)
the display restores normal operation when, on conclusion of evaporator fan standstill, the room temperature or CPT temperature drops below that which has blocked the display (or if a
temperature alarm occurs)
(15)
the value of
∆
t depends on parameter r12 (r0 if r12 = 0, r0/2 if r12 = 1)
(16)
the display restores normal operation on conclusion of evaporator fan standstill (or if a temperature alarm occurs)
(17)
if parameter P3 is set at 0 or 2, the device will function as if parameter d8 were set at 0
(18)
if when defrosting is activated, the operating duration of the compressor is less than the time established with parameter d5, the compressor will remain on for the amount of time necessary to
complete defrosting
(19)
if parameter d8 is set at 2 or 3, the device will operate as if the parameter as been set at 0 and defrosting will be activated when the device has been on totally for the time established with
parameter d26
(20)
if parameter P3 is set at 0, the device will function as if parameter A0 were set at 0 but it will not store the alarm
(21)
during defrosting and dripping and when the evaporator fan is stopped, the temperature alarms are absent, provided that these were signalled after the activation of defrosting
(22)
during activation of the door microswitch input, the maximum temperature alarm is absent, provided the alarm was signaled after the activation of the input
(23)
parameters F13 and F14 have effect when the compressor is off
(24)
parameters F13 and F14 have effect when the compressor is on
(25)
if parameter P3 is set at 0, the device will function as if parameter F0 were set at 2
(26)
parameters F13 and F14 have effect when the evaporator temperature is below the temperature established with parameter F1
(27)
parameters F13 and F14 have effect when the compressor is on and the temperature of the evaporator is below the temperature established with parameter F1
(28)
the parameter can be changed also by implementing the procedure described in paragraph “Setting the configuration parameters”
(29)
if parameter P4 is set at 0, 2, 3 or 4, the condenser fan will function in parallel with the compressor
