When sending a command, the reply will always start with a letter identifying the reply, optionally followed by additional data. Because range of valve is defined, every calibration in this mode is simple go to “open end” and it’s done. Amazon seems only to allow a one month period for this but ‘faulty manufacture’ covers a much longer period than this under the law but is not, as far as I can see, catered for on the Amazon website? It is rh20e to read on hudge monitor with high resolution – layout have fix size, unable to use bigger window – About dialog contain information about GPL II license, but where it sources?

It is strange, that diffence between this two values is bigger than 1. Hello Jiri, at first: I’m about to buy some HR20s to join this very interesting HR20 development. Therefore we cant restart hash function for each “status” packed from HR On worst situation after movements you will have impulses error on position but it is not probbaly win in lotery it absolute sure compare to this: But I fondostat, that it is too complicated.


But it need expert skill of soldering. Report problems and errors please.


Although most of the information has been discovered by other people, I want to repeat it here for a couple of reasons: This is requested by the C standard and casting the parameters to 8bit types doesn’t change this behaviour. This is maybe worst design I have seen in any product ever. But it is more complicate than current communication. You can edit your question or post anyway. Have a single place of reference for this information, instead of needing to look in several different places.

Time for bed now. I have idea to keep motor eye enabled few secons after motor stop. Maybe the “Betty Remote” can be used to control the single units or all.

I have found a Youtube video which identifies how to fix the same problem with a different thermostat, HR It can be maintained remotely. Most of the time the units shall work independently with their own settings and Honfywell just want to override these settings occasionally, e.


The client will also try to receive a wake-up packet from the server, which is of same size. Watch list is full.

And volume of work for RFM12 is sufficient university dissertation for few peoples it is not only few lines of code. We don’t know how to set it via serial line, how to bugug problematic situation etc.

But not allow connect debuger to HR HR20 will transmit status packet next minute with PK3 -step 8: Maybe the have to be updated in future.

But we need to solve resync after HR20 or master is restarted some initial fixed key. So it would consume 8 to 10 Bytes in Configuration Memory. Serial line pin is used for another function.

It can run under Linux or Windows. Any news on the development? I have more than 10 in my house.
