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).
