• 83.0 (3.267) is the maximum depth with extractable terminal blocks
• the panel thickness must not be higher than 8.0 mm (0.314 in)
• working conditions (working temperature, humidity, etc.) must be be-
tween the limits indicated in the technical data
• do not install the instrument close to heating sources (heaters, hot air
ducts, etc.), devices provided with big magnetos (big speakers, etc.),
locations subject to direct sunlight, rain, humidity, dust, mechanical
vibrations or bumps

With reference to the wiring diagram: A
• terminals 4 and 5 are available only in the models with power supply
230 VAC and 115 VAC; terminals 6 and 7 are available only in the
B
models with power supply 12 VAC/DC and 12-24 VAC/DC
• the serial port (by request) is the port for the communication with the
supervision system (through a serial interface, via TTL, with MODBUS
communication protocol) or with the programming key; the port must
not be used at the same time for the same purposes.
Additional information for installation:
• 59.0 (2.322) is the maximum depth with screw terminal blocks
• 83.0 (3.267) is the maximum depth with extractable terminal blocks
• the panel thickness must not be higher than 8.0 mm (0.314 in)
Additional information for electrical connection:
• do not operate on the terminal blocks with electrical or pneumatic
• working conditions (working temperature, humidity, etc.) must be be-
screwers
• if the instrument has been moved from a cold location to a warm one,
tween the limits indicated in the technical data
the humidity could condense on the inside; wait about an hour be-
fore supplying it

• test the working power supply voltage, working electrical frequency
and working electrical power of the instrument; they must correspond
with the local power supply
• disconnect the local power supply before servicing the instrument
• provide the thermocouple with a protection able to protect it against
contacts with metal parts or use insulated thermocouples
• do not use the instrument as safety device
• for repairs and information on the instrument please contact Evco

2 USER INTERFACE
2 . 1 Turning on/off the instrument
To turn on the instrument you have to supply it; to turn it off it is enough
to cut off the power supply.
2 . 2 The display
If the instrument is turned on, during the normal operation the display
will show the quantity you have set with parameter P5:
• if P5 = 0, the display will show the room temperature
• if P5 = 1, the display will show the working setpoint.
2 . 3 Showing the room temperature
• make sure the keyboard is not locked and no procedure is running
• press 2 s: the display will show " Pb1"
• press
To quit the procedure:
• press or do not operate 60 s
• press or as long as the display shows the quantity you have
set with parameter P5 or do not operate 60 s.
2 . 4 Activating the defrost by hand
• make sure the keyboard is not locked and no procedure is running
• press 4 s.
If parameter r5 has value 1 (heating action), the defrost functions will
not be enabled.
2 . 5 Locking/unlocking the keyboard
To lock the keyboard:
• make sure no procedure is running
• press and 2 s: the display will show " Loc" 1 s.
If the keyboard is locked, you will not be allowed to:
• activate the defrost by hand
• modify the working setpoint with the procedure related in paragraph
4.1 (you also can modify the working setpoint through parameter SP).
These operations provoke the visualization of the label " Loc" 1 s.
To unlock the keyboard:
• press and 2 s: the display will show " UnL" 1 s.
2 . 6 Silencing the buzzer
• make sure no procedure is running
• press a button (the first pressure of the button does not provoke its
usual effect).
3 OPERATION
3 . 1 Preliminary information
The operation mainly depends on parameter r5.
3 . 2 Operation with parameter r5 = 0 (cooling action) TYPICAL
71.0 (2.795)

3 . 3 Operation with parameter r5 = 1 (heating action)
4 SETTINGS
4 . 1 Setting the working setpoint
• make sure the keyboard is not locked and no procedure is running
• press LED out 1 will flash
• press or in 15 s; also look at parameters r1, r2 and r3
• press or do not operate 15 s.
You also can modify the working setpoint through parameter SP.
4 . 2 Setting configuration parameters
To gain access the procedure:
• make sure no procedure is running
• press and 4 s: the display will show " P A "
• press
• press or in 15 s to set " -19"
• press or do not operate 15 s
• press and 4 s: the display will show " SP".
To select a parameter:
• press or
