KIOUR REF-FR Series User manual

KIOUR Type REF-FR Model REF-FR-SM V2.0
Electronic digital refrigerator controller (Compact) with ON-OFF function, level water
control, dfrost control (valve or resistance), fan, ON-OFF relay and buzzer ALARM.
Range -45 -+150 °C/°F.
Electronic controller REF-FR is a compact unit for refrigerator’s control. It is ideal for
ventilated refrigerator rooms of low temperatures with dfrost control. It is provided with 5
relays: compressor (30 A, 2HP), fan (5A), valve or resistance (12A), level control (5A), ON-
OFF relay and a buzzer ALARM.
It controls two temperatures with its two sensors in range of -45 - +150 °C/°F, while it has
an Off state, in which all relays are off and OFF is displayed. Also it is provided with one input
for level control (Patent No.1004976) and one input for open door. If the door opens the fan
stops. After four minutes the compressor also stops and the ALARM of the open door is
displayed, while the buzzer is ON.
MANAGING THE UNIT
↵: By pressing ↵the parameter’s menu is displayed.
df :By pressing df for five minutes, a dfrost cycle is forced.
T2 :By pressing Τ2,the temperature of the evaporator is displayed.
RESET
: By pressing for 1 sec, the setup °C or °F is displayed.
:By pressing RESET, the display of the ALARM and the buzzer stops.
:By pressing for 3 sec, the state changes from OFF to ON or from ON to OFF.
MANAGING THE PARAMETERS
1. By pressing ↵, the first parameter SPo (Set Point) is displayed and with the arrow buttons we can see the other parameters
as they appear in the table below.
2. By pressing SET, we can see the value of the parameter and with the arrow buttons we can change the value. We confirm
the new value with the enter (↵), while the name of the parameter is displayed. If we press SET, we cancel the new value and
the name of the parameter is displayed.
3. To exit the parameters, we press ↵.
NOTE: For security reasons, we can’t see all the parameters. To access them all, we enter the value 22 to the Cod parameter.

SERIAL INPUT
Via serial input the instrument is connected to the memory backup (key) or to a network.
1. Memory backup (key): With the key we save the setup of the parameters. We connect the key to the instrument and:
a. By pressing SET and the UP button, the instrument connects to the key and the message Eo is displayed.
b. By pressing UP button, the instrument reads the parameters from the key and the message ro = read O.K. or rF = read
Fail is displayed.
b. By pressing DOWN button the instrument writes the parameters to the key and the messages Yo = Write o.K. or YF =
Write Fail is displayed.The key can be connected to various types of instruments. If you try to read the parameters of a
different instrument, a message rF = read Fail is displayed.
At all instruments and at any time we can perform the write operation. After 10 sec, the key is disconnected automatically.
2. Connect to network: The device can be connected to the CAMIN net (RS485 Modbus protocol) though an interface, NET-IN-1.
CAMIN is an application designed to collect information, watch and fully control a net of devices. The maximum length of the
net can be 1000 meters.

A/A PARAMETERS - DESCRIPTION
1 Spo Set Point temperature control room, Values: LSP to HSP
2 Alo Alarm of low temperature room, Values: -45 - +20 °C
3 Ahi Alarm of high temperature room, Values: 0 - +60 °C
4 dr1 Repeat time of dfrost, Value: 1 - 100 hours
5 Cod Code Number. The number 22 permits scrolling into the other parameters
6 diF Differential working temperature of compressor, Value: 1 - +20 °C
7 dd2 dfrost duration, 0 - 120 min, in which 0 means that dfrost is OFF
8 dP3 Dripping time, 0 - 15 min and compressor’s time pause after the dfrost

:Temperature is displayed continually
:dFr is displayed from the beginning of the dfrost, until time expires
10 dE5 Temperature of dfrost: 1 - +70 °C. Sensor’s malfunction of the evaporator doesn’t make temperature control
and dfrost finishes from expire of time.

buzzer and the indication of the ALARM is displayed. In any case by pressing the down button we stop the
buzzer and the indication of ALARM but the flashing line of the display of the hundreds indicates that there is still
an ALARM. The RESET is valid until the disappearance of the last ALARM.
