2 Use
2.1 Types of plant
Basically, the RVD230 is suited for the control of all types of heating plants in houses or
buildings
• that are connected to a district heat network
• in which the flow temperature of the heating circuit is controlled either weather- or room
temperature-compensated
• in which the control of d.h.w. heating can be integrated as an option
2.2 Types of houses and buildings
Basically, the RVD230 is suited for use in all types of houses and buildings in which the
heating is controlled either weather- or room temperature-compensated. It has been
designed especially for:
• Single-family homes
• Multifamily houses
• Small to medium-size nonresidential buildings
2.3 Types of heating systems
The RVD230 is suited for use with all standard heating systems, such as:
• Radiators
• Convectors
• Underfloor heating systems
• Ceiling heating systems
• Radiant panels
2.4 Heating circuit functions
The RVD230 is used if 1 or several of the following heating circuit functions is / are
required:
• Weather- or room-compensated or weather- and room-compensated flow temperature
control
• Flow temperature control via a modulating seat or slipper valve
• Common or separate heat exchangers for the heating circuit and for d.h.w. heating
• Optimum heating up and setback of the room temperature by learning the switch-on
and switch-off time
• Quick setback with and without room temperature sensor
• ECO function: Demand-dependent switching of the heating system as a function of the
outside temperature
• 7-day program for the heating periods with a maximum of 3 heating periods per day
and varying on times
• Frost protection for the plant and the house or building
• Yearly clock
• Holiday programs
• Independent time programs for space heating and d.h.w.
• Maximum rate of flow temperature increase
• Minimum and maximum limitation of the flow temperature
• Maximum limitation of the room temperature
• Flow alarm
