Greets from Munich, Mario PS: Too many parts is changed, but not finished. Because range of valve is defined, every calibration in this mode is simple go to “open end” and it’s done. Does anyone know a solution for honeywwll Then I want to add small wireless nodes that monitor windows and doors with a small reed contact.

Youtube-Video “How to control a HR20 thermostat per iPhone” It’s only the first experimental step and the development is going on pcb layout, control more then one HR20 and rondostqt on. Learn More – opens in a new window or tab Any international shipping is paid in part to Pitney Bowes Inc.

This problem can be fixed by active current injection on level change, but it need special chipset. A am not able replay this rondodtat now.

Am I doing something wrong with the SVN update? What does it do then and how is the master itself configured? I still have a lot of questions concerning the code and unfortunately not enough time to go through it and understand it honeyewll detail.


Have one to sell? But till now I was not have any accident from this, because we tondostat use 15 second average for temperature controler. I think i will need a timer for it – Timer1 is not used yet? Windows users must use “Serproxy” and connect daemon.

Have to dig deeper into that code first or wait for your solution: If no motion is detected, temperature wil go to normal value given by timer. I could hear that the valve was still open. At this evening the error happens again. The log was made with original version roneostat Has anyone also my strange situation: Pay on pickup, Bank Transfer.

Refer to eBay Return policy for more details.


It is not problem. If the temperature is too high with hysteresisI close the valve and restore lastProcessValue and sumError from the saved values.

I could be more than one reason. Token or n might get lost. I will add an SW interface to it, which all communication classes has to implement, so that a seamless integration of any interface will be possible.

Environment is Linux with avr-gcc version 4. Will usually ship within 1 business day of receiving cleared payment – opens in rondoetat new window or tab.

Hmm, you’re right about the risks of an external module, but I thought it could be easier to connect a hnoeywell to the pin connector but put the module inside. People running the project found a way of connecting inside the case a small digital radio transceiver called RFM12 b.

I will need testers ;- Jiri. Known problem for Rev I want to have log file from 10 hours or more integration of controller error is slow Jiri. So the next release will require only. I still have problems with my very small toilet room with oversized radiator.


But what I found in the morning is, that the switching times I set are not used. The SW is based on. It would save me from laying my hands on every HR20 twice on each holyday: Do not use “On” setting but some temperature only. The Thermotronic doesnt show the measured temp so I cannot analyze as described in doc. The encryption key is gr-20e by the user. I am honeysell busy working on my remote switches with RFM Maybe the “Betty Remote” can be used to control the single units or all.

This bug was fixed and I was not abble to see that you are use too old version before bugfix.

If you have not success with PK nit mean that one or more packets was lost and second side not change PK. May be I can use some part from it.


A keypad and dial; 3. Is it difficult to use the external one? Did i get this right? But it can be useful for others. Currently I did not like to add this settings to the GUI.
