The GB boiler is designed for ease of bhderus. Note that if not otherwise indicated, all the values are transmitted using big endian order the most significant bytes are located at the lowest storage address. It is only sent upon demand. Besides the default programs already defined in the controller, the user can create and edit two fully configurable programs with 42 switching points each per Heating Circuit. If a device wants to access to the bus, he waits until being polled.

This data package is only a monitor of the heating circuit status.

Then it has approximately ms to send its data package until his turn passes. All the devices are connected in parallel to the bus. To modify the values, use the Working Mode datagrams. The parameters of the previous datagram are fully configurable.

Follow these steps when experiencing a 6A error code:. Have a look at the references to find a more complete specification.

I think it may be type 0x01 but not sure. To allow addressing each bus participant has its own identification.

Venting should not be installed into an alcove where air currents can sometimes keep exhaust hanging in the area to be sucked back in. Information travels at bauds and is coded using an 8N1 configurationwhich means eight 8 data bits, no N parity bit, and one 1 stop bit. After some try and error, I have found that, for the RC35 Room Controller, values 39 and 7 for activation and deactivation work better.

Failures from cross contamination are one of the most common reasons for calls in to Buderus’s tech support line. In the previous answer table you can see that the Hot Water Desired Temperature parameter occupies byte 6.

You may also find it in products from Nefit, a company of the same group. A minimum of 3 feet from an inside or outside corner and at least 5 feet below an overhang is necessary so that the fresh air intake does not draw in particulates from the nearby exhaust that will foul sensors within the boiler, causing it to shut down.

For instance, when leaving the house for holidays, you can switch the DHW working mode to off. According to the EMS Wikiwhen the value in byte 4 is greater than 35, the function is started. In the house where I am currently living there is an old Buderus boiler.

The EMS bus is usually accessible though a 3,5 mm service jack located in the front panel of the boiler. Once sent, if the operation is successfully processed by the destination device, it will send an acknowledge message containing only one byte: For this reason, the reference temperature used by the system to heat the house is an outside sensor.

There are more data types than the ones showed here, and I did not decode all the information provided for each message. This is a status message containing some general information about the working conditions of the system. A 3C error code refers to a bad connection to the fan or a faulty fan. This datagram contains the system total operating minutes. The bus master polls continuously to the rest of devices.

The bus master then will repeat every byte sent on the bus as an echo. When the value is 3, the function is stopped. Byte 30 is the controller type 0 — no buxerus, 1 — RC20, 2 — RC3x.
