EWDR 900

EWDR 984

The EWDR984 controller has three analogue inputs for
NTC temperature probes (parameter selectable PTC)
and three digital relay outputs to manage the
compressors, defrost cycle and the fans.
This controller also has a configurable 12V-20mA
output to manage additional loads like alarms.
Defrost cycles can be stopped at a specific time or as
soon as the end cycle temperature is reached (if the
evaporator is equipped with a specific probe). The
three analogue inputs can be used for temperature
control, to manage the defrost cycle and to display the
related values (or to manage the defrost cycle of the
second evaporator).
The values measured by the probes are displayed with
three digits and a minus sign. The decimal point can be
set with a parameter. The buzzer is optional.
All models have TTL connections that enable the
controllers to be used with Copy Card, the quick
programming accessory.
All models have two voltage-free programmable
digital inputs.
The power supply is 230Va.
