RTL 520 Wall-mounted local unit with 0...10V and relay outputs (Multizone System)

RTL 520 Wall-mounted local unit with 0...10V and relay outputs (Multizone System)

RTL 520 is the unit (SLAVE) of the Multizone System for the control of heating and other functions in a single zone. 

  • Wall-mounted
  • Receives power from an auxiliary power supply
  • Controls the local thermal units by means of:
    • On-Off zone valve with 230 V~ actuator and modulation unit with 0...10 Volt – input
    • On-Off zone valve with 24 V~ (or other voltages) actuator, and modulation unit with 0...10 Volt – input
    • Zone valve with 24 V~ (or other voltages) thermal actuator, and modulation unit with 0...10 Volt – input
    • Fixed or variable speed zone circulation pump
    • Zone burner or small boiler with 0...10 Volt – input in POWER or TEMPERATURE
    • On-Off valve and fan-coil ventilator switch with 0...10 Volt – input
    • Any other device that can be controlled via a three-point relay and with 0...10 Volt input –
  • Room sensor (internal or external)
  • Complete configuration of the limits and mode of use permitted to user
  • Three On-Off inputs to be programmed as required
  • Large display with simplified readout 
  • Three operational push-button switches with “intuitive” use 
  • Ability to work even in case of breakdown of the communication with the central unit
  • Customisable unit name
