2. Use
2.1. Types of plant
Basically, the RVL470 is suitable for all types of heating plants that use weather-
compensated flow temperature control. In addition, it can be used for demand-
compensated control of the main flow. Examples:
•
Heating zones with own heat generation
•
Heating zones with a direct or indirect district heat connection
•
Main groups with own heat generation
•
Main groups with a direct or indirect district heat connection
•
Large plants comprising heat generation and several heating zones
2.2. Types of buildings
Basically, the RVL470 is suitable for all types of buildings that use weather-
compensated heating control, but is designed specifically for use in:
•
Multi-family houses
•
Single-family houses
•
Small to medium-size non-residential buildings
2.3. Types of heating systems
The RVL470 is suitable for use with all standard heating systems, such as:
•
Radiators
•
Convectors
•
Underfloor heating systems
•
Ceiling heating systems
•
Radiant panels
2.4. Functions
The RVL470 is used if one or several of the following functions is / are required:
•
Weather-compensated flow temperature control
•

perature control through direct control of a single- or two-stage burner
•
Optimum start / stop control according to the selected weekly program
•
Quick setback and boost heating according to the selected weekly program
•
ECO function: demand-dependent switching of the heating system based on the type
of building construction and the outside temperature
•
Weekly program for building occupancy with a maximum of three setback periods per
day and daily varying occupancy schedules
•
Entry of eight holiday periods per year
•
Automatic summer- / wintertime changeover
•
Display of parameters, actual values, operational statuses and fault status signals
•
Communication with other units via the LPB
•
Remote operation with the help of a room unit and external switches
•
Service functions
•
Frost protection for the plant, the boiler and the building
•
