Temperature Controller

RRV817

Multizone Floor Heating Systems

Multizone model with up to 7 zone outputs by combining 2 RRV817 controllers.

Used for central control of underfloor heating systems in combination with the

QAX810 master room unit and QAW810 zone room units.

Use

Comfort control of underfloor heating systems via zone valve output control:

• Apartments

• Detached houses

• Light commercial applications

• In conjunction with district heating schemes or local heat sources

Functions

The RRV817 temperature controller is designed for central distributed water heating

systems that require easy operation by the building occupant. Up to 5 zones can be

controlled by 1 RRV817 or up to 7 zones using 1 RRV817 in master mode and 1

RRV817 in slave mode. The MMI required to be connected to the controller is the

QAX810 master room unit. Heat source output combined with a maximum of 7 zone

valve outputs control the temperature within each zone of the building. The RRV817

can be configured for various types of heating systems. These include:

• Multizone floor heating system supplied by a district heating scheme

• Multizone floor heating system supplied by a local boiler

• Remote activation from external switch or home automation system

The unit consists of 2 sections: • Cover (clip-on) • Lower housing section containing: − PCB and built-in transformer − Control input / output terminals − Room unit / slave controller bus terminals − RS-422 terminals − LED for power supply and communication indication − Configuration DIP switches Initial application setup of the RRV817 controller to match the connected field components is made by the selection of DIP switch positions. DIP switches are located at the top of the RRV817 controller.

DIP switch 2 RRV817 mode Master Slave QAW810 DIP switches The QAW810 features DIP switches for zone addressing. In addition to QAX810 zone 1, up to another 6 zones can be connected to the RRV817 controller. Functionality Full RCS bus and control of up to 5 zones S2–1 ON OFF S2–2 ON OFF DIP switches at the rear of the QAW810 They allow setting the address in cases where several room units are connected to 1 RRV817 controller. The room units are delivered with default positions = zone 2. DIP no.

Terminal Designation L, N Power supply Function, input or output As a minimum requirement, the connecting cables must comply to H05. Permanent AC 230 V power supply for the RRV817 controller. Commissioning notes Response on start-up When powering up, the QAX810/QAW810 will display all LCD icons for approximately 2 seconds. The LCD will then revert to normal display. The time segments will be flashing if time of day needs to be set. Set time of day as per operation instructions.

Zone valve connections The SUA21 (motor open / motor close) or STA21 (thermal) actuators may be connected to the RRV817 zone outputs: • The SUA21 requires a 3-wire connection comprising AC 230 V permanent power supply (line and neutral) for closing when there is no demand for heat and a switched AC 230 V connection (Y) for opening when there is demand. • The STA21 thermal actuator closes automatically when power is removed; therefore, only a 2-wire connection – neutral and control (Y) – is required.
