1.1 - GENERAL DESCRIPTION
The model
microprocessor that is typically used in cooling applications that
have temperature control with ON/OFF regulation and
defrosting control with set time by means of electrical heating
or hot gas/reverse cycle. The instrument has up to 4 relay
outputs, two inputs for PTC or NTC temperature probes and a
digital input, that can all be configured.
The 4 outputs can be used for controlling the compressor or the
temperature control device (OUT), the defrosting device (DEF),
the evaporation fan (FAN), the room light (LIGHT) or,
alternatively any of the previous functions, using an auxiliary
device (AUX) or an alarm (AL). The two inputs for the PTC and
NTC temperature probes (which can be selected by parameter)
can be used to measure the cell temperature (Pr1) and the
evaporator temperature (Pr2) while the digital input (DIG) can
be programmed to carry out various functions such as
defrosting commands, selecting a different set of temperature
regulations, external alarm signals, activating a continuous
cycle, and activating an auxiliary output etc.
The instrument is equipped with 7 programme keys, a 4-digit
display and 9 LED signals, in addition to an internal buzzer that
is the sound system for alarms. Other important characteristics
of the instrument are: programme parameters protection using
personalised password, Keyboard lock function, switching on
and off (stand-by) of the instrument using the front keys or the

digital input,
device, memorising of two sets of temperature regulations that
can be switched and the possibility of power supply in the
range 100 ... 240 VAC.
