PARAMETERS ALTERATION
Put the selector keys in the desired position and press the key for 10 seconds
until appear the indication
programmed for this function, use the key again to modify this value. After adjusted
the new value for the function wait 4 seconds. The controller will record the new
parameter and will pass to the function
the value of this function. Repite this for the functions
the next to be showed in the display to be configured. After the alteration of the
parameters the display comes to the indication of temperature.

FUNCTIONING DESCRIPTION
Parameters v isualization
When the controller is energized, it will appear the parameters of configuration in the
following order:
REFRIGERATION TIME DEFROST TIME
Defrost on start
The controller will make defrost when energized if the temperature of the
sensor (S1) he will be below of 30 ºC and temperature of the sensor of the evaporator
(S2) below of 15 ºC.
Refrigeration
The compressor turns on and turns off by temperature, according the value adjusted
in the P4 parameter (see table above) during the refrigeration time (P1). After
elapsed the time the controller will initiate a defrost cycle (if the temperature of the
room sensor will be below of 30 ºC), turning off the compressor and the evaporator
fan. During the stage of refrigeration
compressor will be functioning .

Defrost
The defrost will be finished when the temperature in the evaporator (S2) reaches 15 ºC
or the temperature in the room (S1) reach 30 ºC . Otherwise, the defrost will be finished
after elapsed the maximum defrost time configured (P2 or P3). During the defrost the
last temperature measured in the refrigeration cycle will be frozen in the display. The
room
indication will be defrosted when this temperature be reached again or 15 minutes after
the end of the defrost.
Delay
When the instrument is energized or the temperature in the S1 sensor reaches the
setpoint (compressor turn off), the delay (P6) starts to be counted, preventing that the
compressor must be restarted in a period very short. Even than by temperature it wold
be necessary to turn on the compressor the delay (P6) is respected.
External selector
The external selector allows, with a combination of two keys, to define the functioning of
the controller with programmable presets.
