compressor is OFF, it will be forced OFF)

(4)
the unit of measure depends on the parameter /8
(5)
once you have modified the value of the parameter, you will have to switch off the power supply of the instrument
(6)
if the parameter has value 0, the defrost will end by time (parameter d3); if the parameter F7 has value 3 or 4, the evaporator fan will work in accordance with the compressor,
except what you have set with the parameters F4 and F5
(7)
unless the evaporator temperature is below the defrost end temperature you have set with the parameter d2, the defrost will not be activated
(8)
if at the moment of the defrost activation the cabinet temperature is below the value “working se r0” , the instrument will not show temperatures above that value; if
at the moment of the defrost activation the cabinet temperature is above the value “working se r0” , the instrument will not show the increases of the temperature (if
the increase takes place below the value “working se r0” , look at the previous case); the instrument restores the normal operation once the after dripping evaporator
fan delay ends and the cabinet temperature falls below the freeze temperature
(9)
if at the moment of the defrost activation the compressor is ON since a time lower than the one you have set with the parameter, the compressor will be forced ON for a
time such as to finish the time you have set with the parameter
(10) if the temperature alarm does not disappear at the end of the time you have set with the parameter A3, it will further be excluded for the time you have set with the parameter
A6; if the temperature alarm takes place during the defrost and does not disappear at the end of the time you have set with the parameter A7, it will further be excluded for the
time you have set with the parameter A6
(11) the evaporator fan stop temperature is “cabinet temperature - F1” ; you always have to consider the parameter F1 with positive sign.
