• HOMOLOGATION AND INSTALLATION
  Homologation

  • Complies with EN 60730-2-8, EN 60730-1, EN 60335-1 standards.

  Installation and use

  Bidirectional single-phase synchronous motor with internal relay which allows:

  • the control by means of thermostats and chronothermostats with 2 wires;
  • valve closing in case of connection failure with the thermostats/chronothermostats;
  • that one thermostat/chronothermostat can simultaneously control one or more valves;
  • the possibility to control the same valve with few thermostats/chronothermostats connected in parallel.
