1 INSTRUMENT DESCRIPTION
1.1 General Description
Y39 is a digital controller with microprocessor that is typically
used in cooling applications that have temperature control
with ON/OFF control and defrosting control at intervals
time or at reaching temperature by stopping compressor or
by means of electrical heating or hot gas/reverse cycle.
The instrument has up to 3 relay outputs, up to 3 inputs for
PTC or NTC temperature probes and a digital input (alterna-
tive to a temperature input), in addition can be equipped with
an internal buzzer that is the sound system for alarms.
The 3 outputs can be can all be configured for controlling the
compressor or the temperature control device, the defrosting
device, the evaporation fan or, alternatively any of the previ-
ous functions, using an auxiliary device or an alarm.
The 3 inputs for temperature probes can be used to measure
the control temperature, the evaporator temperature, prod-
ucts or aux temperature, while the digital input alternative to
evaporator or Aux temperature input can be programmed
to carry out various functions such as door opened signal,
defrosting commands, selecting a different set of temperature
