1.1 Important
Read these instructions carefully before installing and using the instru-
ment and follow all additional information for installation and electrical
connection; keep these instructions close to the instrument for future
consultations.

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
• according to the safety legislation, the protection against electrical
parts must be ensured by a correct installation of the instrument; the
parts that ensure the protection must be installed so that you can not
remove them if not by using a tool.
1.3 Wiring diagram
With reference to the wiring diagrams:
• port 1 (by request) is the serial 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
• port 2 (by request, not available in EVK223, EVK233 and EVK253 with
power supply 230 VAC and 115 VAC) is the port for the communica-
tion with the remote indicator; the indicator shows the quantity you
have set with parameter P5.
Additional information for electrical connection:
• do not operate on the terminal blocks with electrical or pneumatic
screwers
• if the instrument has been moved from a cold location to a warm one,
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
• do not use the instrument as safety device
• for repairs and information on the instrument please contact Evco
sales network.
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.
Through the digital input (only EVK213, EVK223 and EVK233) it is also
possible to turn off the instrument at a distance (or turn off the instru-
ment via software; in this case the instrument remains connected to the
power supply and the regulators are turned off).
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 cabinet temperature
• if P5 = 1, the display will show the working setpoint
• if P5 = 2, the display will show the evaporator temperature
• if P5 = 3, the display will show “cabinet temperature - evaporator tem-
perature”
• if P5 = 4, the display will show the condenser temperature (only
EVK253).
2.3 Showing the cabinet temperature
