GENERAL
The electronic controllers of the ECP200 BASE series have been designed to control
static or ventilated cold rooms.
The ECP200 BASE 4 electronic 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 ECP200 BASE 2 electronic board allows the user to control the compressor and room
light.
The applications are:
- single-phase refrigeration systems up to 2 HP with off-cycle defrosting.
- out of room unit to be connected to power board for compressor start.
The ABS controller box is simple to install and can easily be wall-mounted as the ECP200
BASE is extremely compact and features an IP65 protection rating.

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 1 mm2.
STANDARD ASSEMBLY KIT
For the purposes of assembly and use, the electronic ECP200 BASE control unit comes
with:
• N° 3 seals, to be fitted between the fixing screws and the box back panel
• N° 1 user’s manual.

INSTALLING THE UNIT
Fig. 1: Undo the 4 screws on the front of the panel.
Fig. 2: 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.
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.
Fig. 3: 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
ECP200 controller 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
To enhance safety and simplify the operator’s work, the ECP200 BASE system has two
programming levels; the first level (Level 1) is used to configure the frequently-modified
SETPOINT parameters. The second programming level (Level 2) is for general parameter
programming of the various controller work modes.
It is not possible to access the 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:
• (t)the UP key is used to increase values and mute the alarm.
• (u)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 SETPOINT (temperature)
2. Hold down the SET key and press the (t) or (u) keys to modify the SETPOINT.
Release the SET key to return to cold room temperature display: the new setting will be
saved automatically.

LEVEL 1 PROGRAMMING (User level)
To gain access to the Level 1 configuration menu proceed as follows:
1. Press the (t) and (u)keys simultaneously and keep them pressed for a few seconds
until the first programming variable appears on the display.
2. Release the (t) and (u)keys.
3. Select the variable to be modified using the (t) or (u) key.
4. When the variable has been selected it is possible:
• to display the setting by pressing SET key
• to modify the setting by pressing the SET key together with the (t) or (u)key.
When configuration values have been set you can exit the menu by pressing the (t) and
(u)keys simultaneously for a few seconds until the cold room temperature reappears.
5. The new settings are saved automatically when you exit the configuration menu.

SWITCHING ON THE ECP200 BASE ELECTRONIC CONTROLLER
After wiring the electronic controller correctly, power up at 230 V AC; the display panel will
immediately emit a beep and all the LEDs will come on simultaneously for a few seconds.
COMPRESSOR ACTIVATION/DEACTIVATION CONDITIONS
The ECP200 BASE controller activates the compressor when cold room temperature
exceeds setting+differential (r0); it deactivates the compressor when cold room
temperature is lower than the setting.
MANUAL DEFROSTING
To defrost just press the dedicated key (see section 5.2) to activate the elements relay.
Defrosting will not take place if the end-of-defrost temperature setting (d2) is lower than
the temperature detected by the evaporator sensor. Defrosting ends when the end-of-
defrost temperature (d2) or maximum defrost time (d3) is reached.

HOT GAS DEFROSTING
Set parameter d1 =1 to defrost in cycle inversion mode.
The compressor relay and defrost relay are activated throughout the defrost phase.
To ensure proper control of the system the installer must use the defrost output: this must
allow opening of the cycle inversion solenoid valve and closure of the liquid solenoid valve.
For capillary systems (without thermostat valve) it is only necessary to control the cycle
inversion solenoid valve via the defrost relay control.
PUMP DOWN FUNCTION
Pump down function is activated when parameter AU=4 (only for version with AUX/Alarm
relay).
Connect pump down pressostat on the digital input 1-3. The compressor is directly
controlled by pressostat.
Connect evaporator solenoid valve on the AUX relay. The solenoid is controlled directly by
thermostat.
PASSWORD FUNCTION
When parameter PA is setting with value different to 0 the protection function is activated.
See parameter P1 for the different protection.
When PA is setting the protection start after two minutes of inactivity. On display appear
000. With up/down modify the number, with set key confirm it.
Use universal number 100 if you don’t remember the password.
