GENERAL
The electronic controllers of the ECP202 EXPERT + BASE series have been designed to
control static or ventilated cold rooms.
The ECP202 EXPERT + BASEelectronic board allows the user to control all the
components on a refrigeration unit such as compressor, evaporator fans, defrosting
elements and cold room light.
The applications are:
-single-phase static or ventilated refrigeration systems up to 2 HP, with off-cycle or
electrical defrosting.
-out of room unit to be connected to power board for compressor, defrosting and fan
start.
-single-phase evaporator control unit with cold solenoid consensus or remote
condensing unit consensus.
The ABS box is easy to install on the wall as the ECP202 EXPERT + BASE has a
minimum footprint and IP65 protection degree.
PRODUCT ID CODES
200202EXBCS Control and management of the compressor,
defrosting heaters, evaporator fans and cold
room light. Two configurable auxiliary relays.
16A differential magnetothermic protection.

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 have a cross-
section of at least 1mm2. Probes extension or shortening could alter their factory
calibration; then proceed with the verification and calibration, using an external
thermometer.
STANDARD ASSEMBLY KIT
The ECP202 EXPERT + BASE electronic controller, for assembly and use, is equipped
with:
•Nr 3 seals, to be fitted between the fixing screws and the box back panel;
•Nr 1 user’s manual.

INSTALLING THE UNIT
Fig. 1: Raise the transparent cover
that shields the magneto-thermal
cut-out switch and remove the
screw cover on the right-hand
side.
Fig. 2: Undo the 4 fixing screws at the front
of the box.
Fig. 3: Close the transparent cut-out switch
cover.
Fig. 4: Open the front of the box, lift it and
slide the two hinges out as far as
they will go.
Fig. 5: Press on the sides of the hinges to
remove them from their seats and
so remove the front panel
completely.

Fig. 6: Use the three existing holes to fix the
box back panel to the wall: use three
screws of a length suitable for the
thickness of the wall to which the
panel will be attached. Fit a rubber
washer (supplied) between each
screw and the box backing.
Fig. 7: Hook the frontal panel back up to the
lower part of the box by inserting the
two hinges in their seats and, bending
them, rotate downwards 180° to gain
access to the electronic board.
Make all electrical connections according to diagram A2.
To carry out the electrical connections reliably and maintain the degree of protection of the box, we
recommend using suitable cable glands and / or pipe clamps to tightly seal all the wiring.
It is advisable to distribute the cables within the panel as neatly as possible. In particular, keep the
power cables away from the signal cables. Use any sealing strips.
Fig. 8: 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.
Give power supply to the panel and carry
out a scrupulous reading / programming
of all the parameters set.
Be careful not to over-tighten the closing screws as they could cause deformation of
the box and alter the correct operation and tactile effect of the panel keyboard.
On all loads connected to the ECP202 EXPERT + BASE electronic controller, install
overcurrent protection devices for short-circuits, to avoid damaging the device. Every
operation and / or maintenance operation must be carried out by disconnecting the panel from the
power supply and from all the possible inductive and power loads to which it is connected; this to
guarantee the maximum safety condition for the operator.
