WHAT IS THE USE
EC 3-195 is an ON-OFF digital thermostat studied for refrigerating systems management through
the compressor, evaporator fans and defrost (for temperature-time) management; besides,
the instrument is provided with one multifunction digital input configurable to interact on the
outputs activity (it presents a request of a defrost cycle, it forces the compressor output to the
status ON, etc.) and with the “Real Time Clock” function (it is studied to establish the real hour
and minute of the day) that can be used to plan up to six daily defrost cycles and to program
working temperature changes (Energy Saving cycle).
In factory the instrument gets preset to accept at the measure inputs PTC/NTC probes used in
refrigeration field at the moment.
EC 3-195 is available in the 74 x 32 mm (2.91 x 1.25 in.) case and it is studied for panel
mounting with the equipped screw or spring brackets.

EC 3-195 was studied for panel mounting, panel cutout 71 x 29 mm (2.79 x 1.14 in.), with the
equipped screw or spring brackets (the overall dimensions and the panel cutout are related in
Fig. 3, the fixing systems suggested by the builder are related respectively in Fig. 4 and in Fig.
5).
ADDITIONAL INFORMATIONS
- the panel thickness must be included from 1 to 5 mm (0.04 to 0.19 in.)
- verify if the using conditions (ambient temperature, humidity, etc.) are within the
limits indicated by the builder (see the chapter TECHNICAL DATA)
- install the instrument in a location with a suitable ventilation, to avoid the internal
overheating of the instrument
- do not install the instrument near surfaces that can to obstruct the air-grating (carpets, covers, etc.), heating sources (radiators, hot air ducts, etc.), locations subject to direct sunlight, rain, humidity, excessive dust, mechanical vibrations or
bumps, devices with strong magnetos (microwave ovens, big speakers, etc.)
- according with the safety norms, the protection against possible contacts with
electrical parts and parts protected with functional insulation only must be ensured
through a correct installation procedure of the instrument; all parts that ensure the
protection must be fixed so that they can not be removed if not with a tool
- if not differently specified at the time of order, the instrument will be equipped with
screw brackets.
ELECTRICAL CONNECTION
EC 3-195 is provided with two screw terminal blocks for cables up to 2.5 mm² (0.38 in.², for
the connection to the power supply, inputs and outputs) and it is provided with one five poles
single line male connector (for the connection to the CLONE configurer/cloner and RICS supervision systems), located on the instrument back panel (the connections to derive are related
in Fig. 6 and they are checkable on the polyester label stuck on the instrument case).
ADDITIONAL INFORMATIONS
- if the instrument is brought from a cold to a warm location, the humidity may condense inside the instrument; wait about an hour before supply the instrument
- verify if the operating power supply voltage, electrical frequency and power of the
instrument correspond to the local power supply (see the chapter TECHNICAL DATA)
- do not supply more instruments with the same transformer
- if the instrument is installed on a vehicle, its power supply must be derived directly
from the battery of the vehicle

PRELIMINARY INFORMATIONS
After derived the connections related in Fig. 6, during the normal functioning the instrument
displays the temperature read by the cabinet probe.
iu3195.wmf
If an alarm should be active the instrument displays the alarm code flashing and the buzzer
utters an intermittent beep as long as the cause that has given it does not disappear (see the
chapter SIGNALS AND ALARMS); pressure on the key T1 during an alarm permits to silence
the buzzer.
EC 3-195 is provided with one working setpoint and with some configuration parameters that
get stored in a non volatile memory and that permit to set the instrument according with one’s
requirements (see the chapter CONFIGURABILITY).
The output K 1 is associated to the compressor and to the working setpoint, it remains activated continuously as long as the temperature read by the cabinet probe reaches the working
setpoint and when it rises above the working setpoint of the hysteresis value (differential) the
output gets reactivated, except during a defrost and a dripping.
The output K 2 is associated to the evaporator fans and it is forced to the status ON, except
what established with the parameters of the family F.
If the instrument was set to manage defrost interval count passed the defrost interval, if the
conditions permit it (the temperature read by the evaporator probe must be below the defrost
stopping setpoint) the instrument automatically presents a request of a defrost cycle, if the
instrument was set to manage real time defrost the instrument automatically presents a request of a defrost cycle at every time established with the parameters of the family Hd, according with the real hour and minute established with the label rtc.
A defrost cycle provides three phases (defrost, dripping and evaporator fans stoppage) connected in cascade since the end of one automatically determines the passage to the following
one.
The output K 3 is associated to the defrost and it remains continuously activated during the
defrost as long as the temperature read by the evaporator probe reaches the defrost stopping
setpoint when the defrost ends and the instrument automatically moves to the dripping; if the
instrument was set to manage defrost to resistances (electrical) during a defrost the compressor output gets forced to the status OFF, if the instrument was set to manage hot gas defrost
(reversal of cycle) during a defrost the compressor output remains continuously activated.
Passed the dripping length from the moment of the defrost end the instrument automatically
moves to the evaporator fans stoppage; during a dripping the compressor output gets forced
to the status OFF.
Passed the evaporator fans stoppage length from the moment of the dripping end the defrost
cycle ends; during an evaporator fans stoppage the evaporator fans output activation gets
disabled.
If the conditions permit it (the temperature read by the evaporator probe must be below the
defrost stopping setpoint) keeping pushed the key T2 for four seconds at least the instrument
presents a request of a defrost cycle.
To the time established with the parameters of the family Hr, according with the real hour and
minute established with the label rtc, the instrument activates an Energy Saving cycle; during
an Energy Saving cycle the compressor output is associated to the auxiliary setpoint, it remains activated continuously as long as the temperature read by the cabinet probe reaches the
auxiliary setpoint and when it rises above the auxiliary setpoint of the hysteresis value (differential) the output gets reactivated, except during a defrost and a dripping.

WORKING SETPOINT
WORKING SETPOINT SETTING (WORKING TEMPERATURE)
To modify the working setpoint value keep pushed the key T3 (the instrument displays the
actual value) and at the same time push and release over and over the key T1 or T2 as long as
the instrument displays the desired value (keeping pushed the key T1 or T2 the value gets
decreased or increased more quickly): after the modification release the key T3 last; during the
pressure of the key T3 the LED L1 flashes quickly to indicate that a working setpoint setting
procedure is running (to the release of the key T3 the instrument automatically turns out from
the working setpoint setting procedure).
ADDITIONAL INFORMATIONS
- for the whole period of a corrupted memory data alarm the access to the working
setpoint setting procedure is refused
- the working setpoint is programmable within the limits established with the parameters r 1 and r 2
- if the parameter r 5 has value 1 the working setpoint can not be modified as long as
the parameter r 5 gets set to 0
- the working setpoint value gets stored in a non volatile memory even if a lack of
power supply happens.

value) and at the same time push and release over and over the key T1 or T2 as long as the
instrument displays the desired value (keeping pushed the key T1 or T2 the value gets decreased or increased more quickly); after the modification release the key T3 last (to the
release of the key T3 the instrument displays the label of the parameter again).
To gain access to the second level enter inside the first level and select the label PA.
Keep pushed the key T3 (the instrument displays the actual value) and at the same time push
and release over and over the key T1 or T2 as long as the instrument displays -19 (keeping
pushed the key T1 or T2 the value gets decreased or increased more quickly): after the modification release the key T3 last (to the release of the key T3 the instrument displays the label PA
again); keep pushed at the same time for four seconds at least the keys T1 and T2 (passed four
seconds the instrument displays the first parameter of the second level).
To select a parameter of the second level push and release over and over the key T1 or T2 as
long as the instrument displays the label of the desired parameter.
To modify the parameter value keep pushed the key T3 (the instrument displays the actual
value) and at the same time push and release over and over the key T1 or T2 as long as the
instrument displays the desired value (keeping pushed the key T1 or T2 the value gets decreased or increased more quickly); after the modification release the key T3 last (to the
release of the key T3 the instrument displays the label of the parameter again).
To turn out from the configuration parameters setting procedure keep pushed at the same time
for four seconds at least the keys T1 and T2 or do not operate with the keys for fifty seconds
at least (time-out exit).
ADDITIONAL INFORMATIONS
- for the whole period of a corrupted memory data alarm the access to the configuration parameters setting procedure is refused
- the modification of the parameter /Ab value has not immediate effect; to obtain this
effect, after the modification turn OFF and turn ON again the instrument
- the modification of a parameter value which unit of measure is the hour or the
minute or the second has not immediate effect; to obtain this effect it must not be
executed during the course of the value
- the configuration parameters values get stored in a non volatile memory even if a
lack of power supply happens.
