1.1 - GENERAL DESCRIPTION
The Y33 model is a digital electronic microprocessor controller that
can be used typically for refrigeration applications. It has
temperature control with ON/OFF regulation and control of
defrosting at time intervals, by arrival at temperature or by length of
time of continuous compressor operation through stopping the
compressor, electric heating or hot gas/cycle inversion. The
appliance has special defrosting optimisation functions and
functions to reduce the amount of energy used by the controlled
system.
The instrument has up to 3 relay outputs, up to 3 inputs for PTC,
Pt1000 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
