1.1 - GENERAL DESCRIPTION
The model W09Y is a digital controller with microprocessor that is
typically used in cooling applications that have temperature control
with ON/OFF regulation 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 (aternative to an
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 previous
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, products 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 regulations, external alarm
