REFRIGERATOR CONTROLLER Model REF-DF-SM Version 4.2
DESCRIPTION
REF-DF-SM Version 4.2
is a compact controller for refrigerator’s control with defrost. Via one
PTC
sensor, it controls room’s temperatures with temperature range -19÷+99°C
(-2÷+210°F). It has defrost control and three relays (compressor, water level, ON-OFF). Also it has an OFF state, in which all relays are OFF and it has one input for level
control and one input for open door. The controller has a serial input and can connect to the

SERIAL INPUT
REF-DF-SM
can connect to the
key programmer
or to the data logger
Mini Logger
or to the
KIOUR
CAMIN
network or to any
modbus network
.
Key programmer:
controller’s parameter values can be saved or retrieved from the programming key. Plug in the programming key to the controller and press at the same
time [
SET
]+[
]. The device connects to the key and the message “
Eo
” is displayed. By pressing [
] the device downloads the parameters from the key and the message
“
ro
” = read O.K. or “
rF
” = read Fail is displayed. By pressing [
] the device uploads the parameters to the key and the message “
Yo
” = Write O.K. or “
YF
” = Write Fail is
displayed. In case of failure (
rF
or
YF
) reenter the key to the serial input and repeat the procedure from the beginning. The key can connect to all
KIOUR
devices. If you try
to read the parameters of a different device, message “
rF
” is displayed. At any time, we can perform the aforesaid operation. After 10sec the key is disconnected.
Data logger Mini Logger:
the controller is connected to the data logger via cable and by programming the parameter
Add = 1
. Automatically, based on selected minutes,
the data logger writes to a microSD memory card the controller’s temperatures, status and alarms.
CAMIN network:
the controller can connect to the
CAMIN
network via an interface
NET-INS-485
.
CAMIN
is an PC software application designed to collect information,
watch and fully control a net of
KIOUR
devices while sending SMS and email in case of an alarm. The maximum length of the net can be 1000 meters.
