Heating controllers

for 1 heating circuit

RVP34..

Heating controllers

for 1 heating circuit and d.h.w.

RVP35..

Multifunctional heating controllers with LPB communication capability for

residential and nonresidential buildings. RVP34.. are suited for the control of

1 heating circuit, RVP35.. for 1 heating circuit and d.h.w. heating. RVP34..

incorporate 2, RVP35.. 3 programmed plant types. Operating voltage AC 230 V.

Use

• Types of plants:

− Heating zone

− Heating zone with district heat connection

− Heating zone and d.h.w. heating with own heat generation

− Interconnected plants consisting of several heating zones each

with 1 heating circuit and integrated d.h.w. heating

• Types of buildings:

− Residential and nonresidential buildings

• Types of heating systems:

− All types of standard heating systems, such as radiator, convector,

floor and ceiling heating systems, radiant panels

• Types of d.h.w. heating systems:

Functions Heating circuit control • Weather-compensated flow temperature control • Weather-compensated flow temperature control with room influence • Weather-compensated flow temperature control, valve installed in the primary return of a district heat zone (only RVP34..) • Demand-based control of the boiler temperature (only RVP35..) D.h.w. control • D.h.w. heating with coil type storage tanks and charging pump (only RVP35..) • D.h.w.
PAGE 3
Equipment combinations Suitable sensors and room units • Flow, return and d.h.w. temperature: All types of sensors using a sensing element LG-Ni1000, for example: − Strapon sensor QAD22 − Immersion sensors QAE212… and QAP21.3 − Collector sensor (solar) QAP21.2 • Room temperature: − Room units (PPS) QAA50.

Operating modes Automatic operation Automatic heating operation with changeover between normal and reduced operation according to scheduler program, automatic ECO function and room unit active Reduced operation Continuous heating to reduced room temperature, automatic ECO function active Normal operation Continuous heating to normal room temperature Protection mode Heating operation off, frost protection ensured Automatic d.h.w.
PAGE 6
Automatic ECO function The automatic ECO function controls the heating system depending on demand; it is deactivated when permitted by the progression of the outside temperature. The function gives consideration to the current, the attenuated and the composite outside temperature, plus 2 adjustable heating limits; 1 for normal heating and 1 for reduced heating. The automatic ECO function requires an outside sensor. It can be deactivated, if required. Max. and min.

Manual charging • Independent of scheduler program and temperature conditions • During protection mode for the heating circuit Priority The heating circuit’s behavior during d.h.w. charging is selectable: • Absolute: Heating circuit pump OFF or heating circuit mixing valve CLOSED and pump ON • Shifting: Heating circuit pump remains ON as long as heating energy is available. Control to the d.h.w. setpoint or the maximum setpoint • Parallel: No priority; heating circuit remains ON. Control to the d.h.w.

Communication (only RVP340, RVP350) Via LPB, for example, locking and forced signals, assignment of d.h.w., master-slave assignments for the time switch, outside temperature signal, heat demand to heat generation, error messages. Manual control The heating system can be controlled manually while d.h.w. heating remains activated. The relays are energized as follows: • Burner ON (only RVP35..

Notes Engineering Electrical installation • • • • The cables of the measuring circuits carry extra low-voltage The cables to the actuator, burner and pumps carry AC 24…230 V Local electrical safety regulations must be complied with Sensor wires should not be run parallel to mains carrying cables powering actuators, pumps, burner, etc.
