1. INSTRUMENT DESCRIPTION
1.1
General description
The model
e31
is a microprocessor based digital electronic
temperature controller that is typically used in cooling ap-
plications with
ON/OFF temperature control
and
defrost
control
with intervals time by
stopping compressor
The instrument has
1 relay output
and
2 NTC temperature
probes
inputs
one of which
can be
configured as digital
input
; it can also be equipped with a
built-in buzzer
for
acoustic report
of the
alarms
.
The operating parameters configuration can be made through
the
keypad
, through the
A01
device connected to the
TTL
port
(standard) or using the
NFC
communication (optional).
