• 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 (9 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.

  The controller calculates the delivery temperature value as a function of the following parameters:

  • external temperature (detected by the probe);
  • regulation broken curve (set);
  • ambient temperature calculated by the controller (optional);
  • ambient temperature detected by the ambient probe (optional).

  By means of controller it is possible to choose the desired output type:

  • mixing valve control (relay “opens” and “closes”);
  • 2-stage output (relay “opens”=stage 1 and “closes”=stage 2);
  • 4-stage output (relay “opens”=stage 1, “closes”=stage 2, “pump”=stage 3 and “aux”=stage 4).

  N.B. with 4-stage operation the two relays (pump control and auxiliary) cannot be used for another purposes.

  It compares the theoretical (calculated) delivery temperature value with the real value, measured by the relative probe and acts on the regulation valve to obtain the desired temperature.

  Programming can be made via GSM phone.
