GENERAL
The electronic controllers of the PLUS100 series have been designed to control static or
ventilated cold rooms.
The PLUS100 AB electronic board allows the user to control all the components on a
refrigeration unit. The board allows the user to control and power the main refrigeration
system components such as the compressor, evaporator fans, defrosting elements and
room light.
There is also a product cooling function: the cooling can be ended as a function of time or
the temperature of the product skewering sensor.

IMPORTANT INFORMATION FOR THE INSTALLER
1. Install the device in places where the protection rating is observed and try not to
damage the box when drilling holes for wire/pipe seats.
2. Do not use multi-polar cables in which there are wires connected to inductive/power
loads or signalling wires (e.g. probes/sensors and digital inputs).
3. Do not fit power supply wiring and signal wiring (probes/sensors and digital inputs) in
the same raceways or ducts.
4. Minimise the length of connector wires so that wiring does not twist into a spiral shape
as this could have negative effects on the electronics.
5. Fit a general protection fuse upstream from the electronic controller.
6. All wiring must be of a cross-section suitable for relevant power levels.
7. When it is necessary to make a probe/sensor extension, the wires must be of the
correct cross-section, which in any case must be at least 1mm2.
STANDARD ASSEMBLY AND USE KIT
The PLUS100 AB system is supplied with the following assembly and utilisation items:
n°1 console fixing bracket;
n°2 temperature sensors (piercing temperature probe not included);
n°1 user’s manual;

GENERAL
To enhance safety and simplify the operator’s work, the PLUS100 AB system has two
programming levels; the first level (Level 1) is used to configure the frequently-modified
SET-POINT parameters. The second programming level (Level 2) is for general parameter
programming of the various controller work modes.
It is not possible to access Level 2 programming directly from Level 1: you must exit the
programming mode first.
KEY TO SYMBOLS
For purposes of practicality the following symbols are used:
• () the UP key is used to increase values and mute the buzzer;
• () the DOWN key is used to decrease values and force defrosting.
SETTING AND DISPLAYING THE SET-POINTS
1. Press the SET key to display the current SET-POINT (temperature).
2. Hold down the SET key and press the () or () keys to modify the SET-POINT.
Release the SET key to return to room temperature display: the new setting will be saved
automatically.

PROGRAMMING THE TYPE OF WORK (User level)
To gain access to the programs menu it is necessary to:
1. Press the key 1 .
2. Use the arrow keys to select the program (PR1....PR6).
3. Press the SET key.
4. After selecting the desired variable it will be possible:
• To modify the setting by holding the SET key pressed and pressing the () or ()
keys.
When the modifications have been made press key 1 to return to program selection (at this
point it is possible to modify another program or start the work cycle).
The STAND-BY key allows the user to exit selection and return to manual storage.
Program PR1: temperature-based cooling
Program for product cooling by positive temperature. Cooling ends when the core of the
product reaches temperature At1. A maximum safety time is set on parameter Ab1. When
cooling is over the controller automatically goes to storage mode with the ST1 setting. ST1
also has the function of controlling the compressor, which stops if the room temperature
reaches temperature ST1-r1. The compressor is reactivated on reaching temperature ST1.

Program PR2: temperature-based freezing
Product freezing program. Freezing ends when the product core temperature reaches At2.
A maximum safety time is set on parameter Ab2. When freezing is over the controller
automatically goes to storage mode with the ST1 setting. The compressor works
continuously.
Program PR3: temperature-based cooling and freezing
Program for product cooling and freezing by positive temperature. When room
temperature drops below the STS setting the switch from cooling to freezing takes place.
Freezing continues until the end of the cycle even in the event of a power cut or a rise in
temperature. Freezing ends when the product core reaches temperature At3. A maximum
safety time is set on Ab3. At the end of freezing the control automatically goes to storage
mode as per the ST3 setting. ST3 also has the function of controlling the compressor
during cooling (the compressor stops if ambient temperature reaches ST3-r1). The
compressor is reactivated on reaching ST3. During freezing the compressor works
continuously.
