• HOMOLOGATION AND INSTALLATION
  Homologation

  • Complies with the law 373, law n.10 dated 9 of January 1991 and D.P.R.412 dated 26 of August 1993.
  • Complies with EN 60730-2-9, EN 60730-2-7 standards.

  Installation and use

  • DIN-rail mounting (6 modules).
  • To ensure an adequate protection install the device on the DIN-rail within a framework.
  • The removable terminals facilitate the wiring and a possible replacement.

  • EV83 purpose is to obtain a certain ambient temperature, starting from delivery temperature and external temperature reading.
    The ambient temperature is set by the user through the configuration menu shown on the display and can take different values ​​depending on the selected program.
  • In the moment when it has been recognized a program type the device calculates the delivery temperature required to obtain the ambient temperature associated with the same program; this is going to be calculated by interpolation using the preset ​​delivery temperature values for four external temperature values ( -10°C, 0°C, 10°C, 20°C). It is possible to optimize the temperature control using the temperature probe EC10.
