1.1 - GENERAL DESCRIPTION
The model TLY 25 is a digital controller with microprocessor that is
typically used in cooling applications that have temperature control
with ON/OFF regulation and defrosting control with set time and
hours intervals (Real Time Clock Defrosting) by means of electrical
heating or hot gas/cycle inversion.
The instrument has 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), an alarm (AL) or, alternatively any of the
previous functions, using an auxiliary device (AUX).
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 4 programme keys, a 4-digit
display and 9 LED signals.
