PARAM. MIN. MAX. U.M. DEF. RESERVED
E9 0 1 - - - 1 reserved
(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 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
(5) the display restores the normal operation as soon as the after dripping evaporator fan delay ends and the cabinet temperature falls below
the one that has locked the display (or if a temperature alarm arises)
(6) if parameter P3 has value 0 or 2, the instrument will work as if parameter d8 had value 0
(7) if (to the defrost activation) the duration of the activation of the compressor is shorter than the time you have set with parameter dA, the
compressor will further remain turned on the fraction of time required to complete it
(8) if parameter P3 has value 0, the instrument will work as if parameter A0 had value 0
(9) the differential of the parameter is 2.0 °C/4 °F
(10) during the defrost, the dripping and the evaporator fan delay 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) if parameter P3 has value 0, the instrument will work as if parameter F0 had value 2
(13) the compressor is turned off spent 10 s since the activation of the input; if the input is activated during the defrost or the after dripping
evaporator fan delay, the activation will provoke no effect on the compressor
(14) the effect is not signalled
(15) make sure the time you have set with parameter i7 is shorter than the one you have set with parameter i9.
