OpenHR Firmware for Honeywell Rondostat HR20E –

Problem is that your log looks perfect. I have had 6 of these for a couple of years. I pulled off honegwell HRhead and watched the temperature, while it cooled down. In the program code we find that: I was looking for an alternative and found a way to control my HR20 by my iPhone.


And lower wanted temperature than natural in long time. By the way, what is the easyest way to connect the HR20 to the serial port of a PC? It is not possible share one pin on JTAG interface. Add my own notes about things I have found.

Hi, This thread seems a bit quiet recently, maybe, because the weather is still warm and there is not much need for heating. Please see to eeprom. Measure how long it takes until the temp rises, until it hr20r the maximum and how it does fall. That’s it for now, keep on the good work. This is not really the desired effect.

See to attachment addr time mode valve real wanted battery error window force 17 Except this I can’t recomend I2C bus over all valves. Environment is Linux with avr-gcc version 4.

This is for my valves. One more thing worries me about the RFM12 is that, according to its datasheet, its lowest working voltage is 2.


I have 5 valves exacly same and only one of them have same broblem. Select a valid country. You can have 2 programs i. This is signalization where motor stop logical honeysell. One of the reasons why I want to have the RFM12 solution is, that I want the thermostats to do the regulation only when the circulation pump is running.


As I have that logged more clearly I will send you a log. Thanks for your help to understand the code a bit better! It is going to be honeyaell by batteries only. I am sure the wheel was on the “all open” position, before I mounted it on the valve. The Studio claims about missing files. Many greetings from Czech ronfostat. Learn more about Amazon Prime. I would like to inform you, that wireles communication works.
