GENERAL FEATURES
DESCRIPTION:
Three-phase electrical panel for temperature and humidity control for evaporating unit with
electrical heaters for hot.
To match with a compressor rack or a remote condensing unit.
Magnetothermic circuit breaker protection accessible from the front panel added to an
innovative form makes this panel a perfect and functional choice to provide safety,
protection, control of temperature and humidity with specific seasoning functions.
Programming up to five recipes, of seven phases each, settable and customizable (the
usable functions depend on the type of the panel).
Collectively the panel permits to control cold solenoid, condensing unit enabling, hot
heaters, ventilation (up to 800W), cold room light, humidification enabling, air exchange,
pauses, de-humidification, defrosts (up to 7500W), alarms.
APPLICATIONS:
-Seasoning/drying rooms.
-Germination rooms with day/night cycles.
-Storage rooms with or without humidity control.
MAIN FEATURES:
-Backlit LCD screen.
-Clock and calendar.
-Manual or automatic mode.
-Up to 5 formula completely customazible automatic management of 7 phases for each
formula (dripping first phase, seasoning/conservation last phase). simple programming
and selection of set formula. possibility of join together more formula for exceeding the
7 phases limit.
-Heat and humidity can be excluded to manage storage cells with defrost activation.
-Temperature to one decimal point.
-Password for keypad lock.
-Day/night cycle for germination systems with double set-point.
-Dehumidification program with cold or heat call.

IMPORTANT GENERAL 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 signaling wires (e.g. probes and digital inputs);
3. Do not fit power supply wiring and signal wiring (probes and digital inputs) in the same
raceways or ducts;
4. Minimize the length of connector wires so that the wiring does not have a spiral shape;
5. All wiring must be of a cross-section suitable for relevant power levels;
6. Place a general protection fuse upstream from the electronic controller;
7. When it is necessary to extend the probes, the wires must have a cross-section of at
least 1mm². The probes extension or shortening could alter the factory calibration; then
check and calibrate through an external thermometer.
KIT FOR MOUNTING
PLUS300 EXPERT U THR electronic controller kit, for assembling and using, contains:
• N° 4 seals, to be fitted between the fixing screws and the box back panel.
• N° 1 use and maintenance manual.
• N° 1 electrical drawing.
• N° 1 drilling layout.
• N° 2 probes NTC 10K 1% .

INSTALLATION
Raise the transparent cover that shields the magneto-thermal cut-out switch and
remove the screw cover on the right-hand side.
Undo the 4 fixing screws at the front of the box.
Open the front of the box, lift it and slide the two hinges out as far as they will go. Bend
the hinges and rotate the front panel by 180° downward to get access inside the panel
Using the furnished drilling layout make four fixing holes on the wall. Using holes made
on previous point fix the bottom with 4 screws of a length suitable for the thickness of
the wall to which the panel will be attached. Fit a o-ring (supplied) between each screw
and the box backing
Make all the electrical connections as illustrated in the diagram for the corresponding
model (see relative table in APPENDICES).
To effect correct electrical connection and maintain the protection rating, use
appropriate wire/raceway grips to ensure a good seal.
Route the wiring inside the unit in as tidy a fashion as possible: be especially careful to
keep power wires away from signal wires. Use clips to hold wires in place.
Close the front panel, making sure that all the wires are inside the box and that the box
seal sits in its seat properly.
Tighten the front panel using the 4 screws, making sure the O-rings on the head of
each screw are used.
Power up the panel and carry out thorough reading/programming of all the
parameters.
Be careful not to over-tighten the closure screws as this could warp the box and
compromise proper operation of the membrane-type keypad.
Install short-circuit overload safety devices on all the power cables connected to the
PLUS300 EXPERT U THR so as to prevent damage to the device. Work and/or
maintenance must ONLY be carried out on the unit after disconnecting the panel from
the power supply and from any inductive/power loads: doing so allows the worker to
do his job safely.

GENERAL FEATURES
For safety reasons and to simplify the operator’s work, the PLUS300 EXPERT U THR has
two programming levels; the first level is used to modify SETPOINT parameters (i.e. those
parameters that are changed frequently). The second level is for general parameter
programming of the various board work modes.
It is not possible to access the first programming level directly from the second level: you
must exit the programming mode first.
KEY TO SYMBOLS
For practical purposes the following symbols are used:
• ()indicates the UP key used to increase value and to force the defrost / pause;
• ()indicates the DOWN key used to decrease value, to mute the alarm and to force
the air changing.
SET POINT PROGRAMMING AND DISPLAYING
1. Push the SET key to display the current SET POINT (temperature and humidity
alternately).
2. Press the SET key and push one of () or () keys to modify the SET POINT value.
Release the SET key to return to cold room temperature display; modifications are saved
automatically.
