INSTRUMENT DESCRIPTION

1.1

General description

The model e33 is a microprocessor based digital electronic
temperature controller that is typically used in cooling ap-
plications with ON/OFF temperature control and defrost
control at time intervals, by arrival at temperature or by
length of time of continuous compressor operation through
stopping the compressor, electric heating or hot gas/cycle
inversion.
The instrument has up to 3 relay outputs and up to 3 NTC
temperature probes inputs one of which can be config-
ured as digital input; it can also be equipped with a built-in
buzzer for alarms acoustic report.
