GENERAL
To enhance safety and simplify the operator’s work, the ECP200 BASE 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:
• () the UP key is used to increase values and mute the alarm.
• () 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 () or () keys to modify the SETPOINT.
Release the SET key to return to cold room temperature display: the new setting will be
saved automatically.

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. If the Pump-down function is selected (Parameter
AU=4) refer to chapter 2.14 for the compressor activation / deactivation conditions.
MANUAL DEFROSTING
To defrost just press the dedicated key (see section 2.2) 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-ofdefrost temperature (d2) or maximum defrost time (d3) is reached.

CHAP. 2 - Parameter programming
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.
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.

Remove power from the electrical panel, open the front panel and unscrew the 6 fixing
screws of the electronic board.
Configure the jumper from JUMPER JP2
(placed on the front of electrical board near
the display far down on the right) following
one of the ensuing options.
RS485 output selection:
Insert the jumper JP2 on 3-2 position and set
the 2nd level variable AU=3 (TeleNET) or
AU=7 (Modbus-RTU).
The connection clamps are RS485_(A) and
RS485_(B) on board of electrical board.
Remember besides to assign an univocal net
address in the current instruments net. (Ad
2nd level parameter).
Warning! with this configuration auxiliary relay
is disabled.
AUX/Alarm relay selection:
Insert the jumper JP2 in 2-1 position and set
the 2nd level variable AU to a value different
from 3 and 7 according to the needed
function. Clamps of configurable relay clean
contact are on AUX/ALL output, on board of
electronic board.
