RVL480

Digital climatic controller for temperature control, with or without optimization with a room sensor, 6 pre-installed program types

System types:

• Control of a mixing valve serving a heating zone
• Control of a 1 or 2-stage burner
• Control of a valve in the return circuit of a heating zone with connection to a district heating circuit
• Demand-dependent control (precontrol) of a mixing valve / of the boiler temperature / of a heat exchanger (heat demand
• Pre-heating control of a mixing valve (of a boiler / of a heat exchanger (heating demand via data bus)

Additional functions

The RVL480 controller also offers the following functions (without the need for additional modules):

• Display of parameters, actual values, operating states and fault status signals
• 7-day program with 3 heating periods per day
• 2 additional programs, each with 3 switching periods per day
• Automatic summer/winter changeover
• Holiday program (up to 8 holiday periods per year)
• Optimum start/stop in accordance with the heating program (with or without room influence)
• Automatic ECO function, depending on the outside temperature and the type of building construction
• Optional remote selection of operating modes (via room unit or external switch)
• Scalable DC 0…10 V output for passing on the heat request to other devices
• Quick setback and boost heating
• Preselection of flow temperature setpoint via external contact
• Minimum and maximum limitation of the flow temperature
• Minimum and maximum limitation of the return temperature (shifting / constant)
• Maximum limitation of the room temperature
• Communication with other devices via the data bus
• Limitation of the return temperature differential (DRT) for district heat applications
• Frost protection and pump protection
• Flow temperature alarm
