3.1 Operating

modes

The

RVP211

provides the following operating modes:

Automatic operation normal / protection mode

Automatic changeover between normal temperature and protection mode

according to the 24-hour or weekly program

Automatic d.h.w. heating
Load-dependent switching on and off of the heating in function of the

outside temperature while giving consideration to the building’s thermal
inertia (ECO automatic energy saver)

Optional remote operation with the help of a room unit
Frost protection is ensured

Automatic operation normal / reduced

Automatic changeover between normal and reduced temperature accord-

ing to the 24-hour or weekly program

Automatic d.h.w. heating
Load-dependent switching on and off of the heating in function of the

outside temperature while giving consideration to the building’s thermal
inertia (ECO automatic energy saver)

Optional remote operation with the help of a room unit
Frost protection is ensured

Setback mode

  Continuous heating to the reduced temperature
  Automatic d.h.w. heating
  Load-dependent switching on and off of the heating in function of the

outside temperature while giving consideration to the building’s thermal
inertia (ECO automatic energy saver)

Frost protection is ensured

Normal mode

  Continuous heating to the normal temperature
  Automatic d.h.w. heating
  No ECO automatic energy saver
  Frost protection is ensured

D.h.w. heating only

  Automatic d.h.w. heating
  Control of heating to protection mode
  Frost protection is ensured

Protection mode

Heating to the frost protection level
Frost protection is ensured

Manual operation

  No control
  Heating circuit pump runs
  Control with seat or slipper valve: relay de-energized

Control with burner: boiler always ON

D.h.w. charging pump runs or d.h.w. changeover valve is deactivated

The

RVP201

does not provide

“d.h.w. heating only”.
