(1) the unit of measurement depends on parameter P2
(2) appropriately set the parameters relative to the regulators after modification of parameter P2
(3) the parameter only has effect after a power cut that occurs when the instrument is on
(4) the time established with the parameter is counted also when the instrument is off
(5) if parameter C1 is set at 0, the delay from the conclusion of the cabinet probe error will be 2 min
(6) the parameter differential is 2.0 °C/4 °F
(7) on instrument switch-on, the temperature of the condenser is already above that established with parameter C7, parameter C8 will have no effect
(8) the instrument memorises the defrosting interval count every 30 min. The modification of parameter d0 has effect from the conclusion of the previous defrosting interval or from the activation of defrosting in manual
mode
(9) the display restores normal functioning when, on conclusion of evaporator fan standstill, the cabinet temperature drops below that which has blocked the display (or if a temperature alarm occurs)
(10) if parameter P3 is set at 0 or 2, the instrument will function as if parameter d8 is set at 0
(11) if, on activation of defrosting, the switch-on duration of the compressor is less than the time established with parameter d15, the compressor will remain on for the fraction of time required to complete it
(12) if parameter P3 is set at 0, the instrument will function as if parameter A0 is set at 0 but will not memorise the alarm
(13) during defrosting, dripping and evaporator fan standstill, the temperature alarms are not present as long as these have occurred after activation of defrosting
(14) during the activation of the door micro switch input, the maximum temperature alarm is absent on the condition that these occur after activation of the input
(15) if parameter P3 is set at 0, the instrument will function as if parameter F0 is set at 2
(16) the parameter is also modified by operating with the procedure given in paragraph 4.8.1
(17) if parameter P4 is set at 0, the condenser fan will function in parallel to the compressor
(18) the compressor is switched-off after 10 s from activation of the input. If the input is activated during defrosting or standstill of the evaporator fan, the activation will not have any effect on the compressor
(19) the instrument memorises the alarm on expiry of the time established with parameter i2. If parameter i2 is set at -1, the instrument does not memorise the alarm
(20) make sure that the time established with parameter i7 is lower than that established with parameter i9
(21) to prevent damage to the utility connected, modify the parameter when the instrument is off
(22) if parameter u2 is set at 0, instrument switch-off will cause the cabinet light or auxiliary output to switch off (on successive switch-on of the instrument, the utility will remain off); if the parameter u2 is set at 1, instrument
switch-off will not cause the cabinet light or auxiliary output to switch off (on successive switch-on of the instrument, the utility will remain on).
time that must pass in absence of multipurpose input alarms (“iA” code) so that the alarms contactor is reset (only if i5 = 4)
time that must pass without activation of the door micro switch input (after the cabinet temperature has reached the work set-point) so that the Energy Saving function is
activated automatically (it affects the evaporator fan only if F0 = 1 or 2)
0 = the function will never be activated automatically
minimum duration of door micro switch activation such to cause the exclusion of the consequent evaporator temperature value from those used for the calculation of the
relative average (for the activation of defrosting; only if d8 = 3); see also d17
minimum total duration of door micro switch activation such to cause the exclusion of the consequent evaporator temperature value from those used for the calculation
of the relative average (for the activation of defrosting; only if d8 = 3); see also d17
number of door micro switch input activations such to cause the activation of defrosting
0 = defrosting will never be activated due to the effect of door micro switch input activation
minimum duration of door micro switch input activations such to cause the activation of defrosting
0 = defrosting will never be activated due to the effect of door micro switch input activation
DIGITAL OUTPUTS
utility managed by the fourth output (21)
0 = CABINET LIGHT - in this case the key, parameters i0 and u2 will have meaning
1 = DEMISTING HEATERS - in this case the key and parameter u6 will have meaning
2 = AUXILIARY OUTPUT - in this case the key, parameters i5 and u2 will have meaning
3 = ALARM OUTPUT - in this case, parameter u4 will have meaning
4 = DOOR HEATERS - in this case, parameter u5 will have meaning
5 = EVAPORATOR VALVE - in this case, parameters u7 and u8 will have meaning
6 = CONDENSER FAN - in this case, parameters P4, F11 and F12 will have meaning
enabling of cabinet light or auxiliary output switch-on/off in manual mode when the instrument is off (only if u1 = 0 or 2) (22)
1 = YES
enabling deactivation of the alarm output with silencing of the buzzer (only if u1 = 3)
1 = YES
cabinet temperature below which the door heaters are switched-on (“u5 - 2.0 °C/4 °F, only if u1 = 4) (6)
duration of demisting heaters switch-on (only if u1 = 1)
cabinet temperature below which the evaporator valve is disabled (relative to the work set-point, i.e. “work set-point + u7”) (only if u1 = 5) (6)
type of evaporator valve contact (only if u1 = 5)
0 = normally open (active valve with closed contact)
1 = normally closed (active valve with open contact)
enabling of the buzzer
1 = YES
