1 General

DOMOTESTA RDO heating controllers are consequently designed to the requirements of customers and installers.

DOMOTESTA heating controllers exist in three different ranges: RDO3xxA: With simple operation concept and LC display, able to communicate and network able RDO2xxA: With simple operation concept and LC display, for standard applications RDO1xxA: With analogic operation concept, for simple standard applications

The large LCD allows a comprehensive overview of all important information. A rotary knob each serve s for operation-mode setting and temperature setpoint adjustment. All other functions are push-button operated. This controller is especially designed for use in heating applications that involve cascade operation, solar or district heating, gas heating or complex heating plants. Heating circuits are weather compensated, DHW control is temperature guided. An optional room temperature sensor with or without remote control unit allows automatic heating adaptation. Two configurable low-voltage outputs and freely assignable digital inputs increase the functionality of the controller. The range-wide compatibl e terminal assignment reduces wiring effort and eases application-specific controller selection. It is available in following executions with different functions.

RDO353A000: 2-stage or modulating burner; boiler circulating pump,

1 mix-heating circuit (3-point valve and pump), DHW pump.

RDO383A000: 2-stage or modulating burner; boiler circulating pump,

2 mix-heating circuits (3-point valve and pump), DHW pump.

This manual contains in its front section all necessary information for the user concerning operation and settings. The installer finds in the middle section details concerning installation and electri cal wiring. In the back section is the list of parameters and the programming protocol. This protocol is to be filled in by the service engineer.

Important:

This manual, together with the wiring diagram should be kept near the heating, easily accessible to the service engineer. The controller has been developed for use with a great variety of systems. It is possible that herein mentioned functions or accessories are not part of your heating system.

1.1 Main functions

Controller:

The controller consists in principle of three “independent” control circuits.

A heat generator, usually a boiler with burner or a heat pump or solar collector with buffer storage, supplies the energy required.

The heating circuit (room heating) demands energy. Its amount depends mainly on the desired room temperature, the weather condition and the type of building.

The DHW heating demands energy. It’s amount depends on the water temperature in the boiler and hot water demand.

Generation of heat energy

Room heating

Domestic hot water heating

2 Safety regulations

2.1 Signs and notes

The danger signs and notes shown below and used in this document refer to the following instructions.

Warning: A ”Warning” indicates actions or procedures which, if not performed correctly may lead to

personal injury or a safety hazard. Strictly observe the instructions supplied.

Caution:

A ”Caution” indicates actions or procedures which, if not performed correctly may lead to

faulty operations or destruction of the controller or system components. Strictly observe the instructions supplied.

Note:

A ”Note” indicates actions or procedures to avoid unexpected results or as tips for

easier work. They include extra information for the user.

2.2 Correct usage

The product accompanying this manual complies with the technical regulations, valid at the time of production, and with CE standards.

It may only be used in impeccable condition. Please inform your service engineer if you notice any defect. In case of malfunction please switch the controller off (mains fuse) and consult the checklist “Trouble shooting”.

This heating controller may only be used in the following applications:

- Heat production by oil or gas boiler, district heating or heat pumps

- DHW heating with hot water boiler

- Heating operation for direct and/or mix-heating circuit All safety provisions specified by national or international regulations must be observed under all

circumstances:

- Regulations concerning electricity (mains current)

- Regulations concerning heating equipment

- Regulations concerning authorised personnel

User manual: RDO3x3A

2.3 Authorised personnel

Mounting, electrical installation, setting-up and maintenance of the device may only be carried out by trained personnel, authorised by the operator of the facility. Personnel must absolutely and without fail read and understand this manual before carrying out its instructions.

Any modification or alteration of the device is prohibited. Any work on the device (repairs, modifications) may only be carried out by the manufacturer or bodies authorised by him.

2.4 Product-specific dangers

Touching of the terminal bars and fastened or unfastened wires directly or with conductive materials constitutes the danger of electrical shock. The controller terminal and/or wires may be supplied by external connections, even if the controller seems not to be life (consult wiring diagram).

Before any work is carried out on electrical parts of the heating system (i.e. controller and/or burner, pumps, switches, limiters, sensors, etc.), all mains fuses must be switched off.

3 Operation

Operation is performed on differently accessible user levels. Thus unwanted faulty parameter setting by non-experts is prevented. During regular, undisturbed operation, the basic indication on the LCD info rms of operation mode, errors or superimposed modes. Pressing of any key will switch on the illumination. Further operation is described below. If there is no key pressed during a period of time, the display falls back to basic indication and illumination is switched off. The following user levels are available:

Operation level I:

Simple operation settings With cover closed, only the operation modes: normal, reduced and frost protection as well as the temperature setpoint adjustment may be set.

Operation level II:

Advanced operation settings When the cover is opened, with basic indication on, additional modes, all time switch settings and setpoint adjustments are accessible. Additional information about values and settings can be retrieved.

Expert level I:

Parameter setting By means of special key sequences (from operation level II) the controllers basic parameters can be altered.

Expert level II:

System test By means of special key sequences (from expert level I) the relay functions of master and slave controllers and can be tested.

This chapter describes the operation for the enduser. (see also the mini guide "Manual" in the front panel of the controller)
