1.1 - GENERAL DESCRIPTION
TLZ 11 P is a digital microprocessor based thermocontroller for
Heating or Cooling applications and ON/OFF control mode.
The instrument has up to 2 relay outputs, one input for Pt1000 or
NTC (PT-24C2 up to 300°C) temperature probes and a digital
input, that can be configured.
The 2 outputs can be used for controlling the temperature control
device (OUT) and an alarm (AL).
The instrument is equipped with 4 programme keys, a 4-digit
display and 2 LED signals, in addition to an internal buzzer that is
the sound system for alarms.
Other important characteristics of the instrument are: programme
parameters protection using personalised password, switching on
and off (stand-by) of the instrument using the “U” front key,
configuration of parameters via the KEY 01 device and the
possibility of power supply in the range 100 ... 240 VAC.
