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
