(1) the unit of measure depends on parameter P2
(2) set the parameters related to the regulators appropriately after the modification of the parameter P2
(3) if parameter C1 has value 0, the delay since the end of the cabinet probe error will however be 2 min
(4) the differential of the parameter is 2.0 °C/4 °F
(5) if (when you turn on the instrument) the condenser temperature is above the one you have set with parameter C7, parameter C8 will have
no effect
(6) the instrument stores the count of the defrost interval every 30 min; the modification of parameter d0 has effect since the end of the previous
defrost interval or since the activation of a defrost by hand
(7) the display restores the normal operation as soon as the defrost ends and the cabinet temperature falls below the one that has locked the
display (or if a temperature alarm arises)
(8) if parameter P4 has value 0, 2 or 3, the instrument will work as if parameter d8 had value 0
(9) if parameter P4 has value 0 or 3, the instrument will work as if parameter had value 0
(10) during the defrost the temperature alarms are not enabled, on condition that they have arisen after the activation of the defrost
(11) during the activation of the door switch input the upper temperature alarm is not enabled, on condition that it has arisen after the activation
of the input
(12) the compressor is turned off spent 10 s since the activation of the input
(13) the effect is not signalled
(14) make sure the time you have set with parameter i7 is shorter than the one you have set with parameter i9
(15) erase the working days after the modification of parameter t1
(16) the instrument counts the working days also when it is turned off via software.
