VBus

VBus is a simple 2 wire data bus system for connecting RESOL controllers to performance displays, dataloggers, computer systems and external modules. All VBus devices use a common protocol so data can be freely shared between any compatible devices. The data can be downloaded and stored using RESOL Service Centre software and various connection options. Cable lengths upto 100m+ are possible. (using good quality screened cable - available from stock)

Smart Display SD3 (15% price cut in July price list)

The RESOL Smart Display is designed for simple connection to RESOL controllers with RESOL VBus®. It is used for visualising data issued by the controller: collector temperature, storage temperature and energy yield of the solar thermal system. The use of high-efficient LEDs and filter glass assures a high optical brilliance and good readability even in poor visibility conditions and from a larger distance. An additional power supply is not required. Simultaneous visualisation of collector and storage temperature as well as heat quantityOne 6-digit and two 4-digit 7-segment LED displaysSimple connection via RESOL VBus®Power supply via RESOL VBus®Outstanding designTechnical data

Alarm module AM1

The Alarm module AM1 is designed to signal system failures. It is to be connected to the VBus® of the controller and issues an optical signal via the red LED if a failure has occurred. The AM1 also has a potential-free relay output, which can e. g. be connected to a building management system (BMS). Thus, a collective error message can be issued in the case of a system failure.

Depending on the controller and the sensors connected, different fault conditions can be signalled, e. g. sensor failures, excess or negative system pressure as well as errors in the flow rate, such as a dry run of the pump.
The Alarm module AM1 ensures that occurring failures can be immediately recognised and repaired, even if the system and the controller are difficult to access or located in a remote place. Thus, the reliability and the stable yield of the system are ensured.

Datalogger DL2

This additional module enables the acquisition and storage of large amounts of data (such as measuring and balance values of the solar system) over a long period of time. The DL2 can be configured and read-out with a standard internet browser via its integrated web interface. For transmission of the data stored in the internal memory of the DL2 to a PC, an SD card can be used. The DL2 is appropriate for all controllers with RESOL VBus®. The datalogger can be connected directly to a PC or router for remote enquiry and thus enables comfortable system monitoring for yield monitoring or for diagnostics of faults.

Large display GA3

The RESOL GA3 is a completely mounted large display module for visualisation of collector- and storage temperatures as well as the heat quantity yield of the solar system via one 6-digit and two 4-digit 7-segment-displays. Suitable for public display/reception areas. An easy connection to all controllers by RESOL VBus® is possible.

Stainless steel frame with high quality multiplex wood elements and mounting plates for interior wall mounting. The front plate is made of antireflective filterglass and is printed with a light-resistant UV-lacquering.The universal RESOL VBus® allows the parallel connection of 8 large displays as well as additional VBus® modules. The bus line can be extended using a standard two-wire line.

STA-W (kWh output module)

The kWh output module is an interface designed for the exchange of heat quantity measurement values between RESOL devices and external appliances. It can be connected to a RESOL controller or a calorimeter via the RESOL VBus®. Whenever the heat quantity increases by 1 kWh, the module operates a potential-free contact which is connected to the central building control system. The total number of operated contacts can be visualised as heat quantity by the software of the central building control system.

STA (Signal Translation Adapter)

The adapter is used for controlling the pump via a PWM- or 0-10-V-signal. Via the VBus® the adapter receives information from the controller about the pump speed. The speed is converted into a PWM- or direct voltage signal and put out to the corresponding terminals. A signal corresponding to the speed is only available if the corresponding relay is designed for pump speed control. Otherwise, a signal depending on the position of the relay, for the on or off state is transmitted.

Interface adapter VBus®/LAN

The VBus®/LAN interface adapter is designed for the direct connection of the controller to a PC or router. It enables easy access to the controller via the local network of the owner. Thus, controller access, system parametrisation and data read-out can be effected from every workstation of the network. The VBus®/LAN interface adapter is suitable for all controllers equipped with a RESOL VBus®. A full version of the RESOL ServiceCenter software is included.

Interface adapter VBus®/PWM

The VBus® / PWM interface adapter enables the speed control of two high-efficiency pumps even without an integrated PWM-output on the system`s controller. The adapter is installed between the VBus® output of the controller and the PWM-input of the high-efficiency pump, where it transforms the VBus® data packets into a 0-10 V or a PWM signal. Speed control of high-efficiency pumps for controllers without integrated PWM outputsConvertible from PWM to 0-10 V signal

Interface adapter VBus®/USB

The new VBus®/USB interface adapter is the interface between the controller and a personal computer. With its standard mini- USB-Port it enables a fast transmission of system data for processing, visualising and archiving as well as the parametrisation of the controller via the VBus®. A full version of the RESOL ServiceCenter software is included.

ServiceCenter Software RSC
The modular designed software enables PC-recording of the data measured by the controller, editing of the data files for further processing by standard spreadsheet programs and visualisation of individual systems with all measuring and balancing values.
VBus®-record and Designer as described before in light-version, but additionally:Designer: allows the positioning of the VBus® values on a customised background graphic; in this way, system visualisations for any solar system can be presented in real-timeDataloggers: possibility to manage any number of datalogger; the ServiceCenter establishes connection at the push of a button, reads out the data, if necessary, deletes data from the logger and converts data into a text fileParametrisation: DeltaSol® M, E, ES and the BS-series (and future versions of the product family) can be configurated user-friendly with a PC; the values are checked for domains and possible overlapping and are transferred to the controller via VBus®.
