INSTRUMENT DESCRIPTION

1.1

General description

The TLZ 35 is a microprocessor digital controller typically
used in cooling applications with ON/OFF temperature
control and stop compressor defrost control at pre-set
time intervals.
The instrument has up to 2 relay outputs, 1 PTC or NTC
input for temperature probes and 1 configurable digital
input.
The 2 outputs can be used to control the compressor or the
temperature control device (OUT) and an alarm (AL).
The instrument is equipped with 4 program keys, a 4-digit
display and 3 LED signals, in addition to an internal
buzzer that is the sound system for alarms.
Other important characteristics of the instrument are: pro-
gram parameters protection using personalised password,
switching on and off (stand-by) of the instrument using the
front key, parameters configuration via the A01 device and
the possibility to power the instrument with mains between
100 ... 240 VAC.
