If you want to switch a circulation pump, you will need a suitable power relay or contactor, which in turn is driven by K1. This is because some systems have constant hot water circulation so users can draw hot water from the tap immediately. However, the software supports different operation modes providing much more than a mere emulator.
Use the PC software to calibrate the temperature sensors. The temperature signals from the sensors on the return line are correlated in the same manner, and ideally the time offsets obtained for the supply and return lines should be the same.
HHEmu is a multi-threaded application avrl threads.
Pololu – Free Elektor magazine April
Never allow this circuit to come in direct contact with the AC power voltage. Reprogramming a few fuses is necessary to enable the boot loader to work properly, but first you should study the microcontroller data sheet carefully. Other magazines on electronics, radio, computers and robotics can be downloaded from Free library here. All free magazines that can be downloaded: Check the updates for details and more features.
It is rated for only relatively low voltages and currents. Pending trouble codes are failures detected in the current or last completed driving cycle that have not been confirmed in a second driving cycle, yet.
If 00 is given, negative response codes are switched off.
Metering, adjustment, matching Antennas. U4a amplifies the sensor signal by a factor of approximately 8. After the sensors have been connected to the board, the initial temperature curves as yet uncalibrated should appear in the PC program. Flow transducers are available for measuring the flow velocity, but installing a flow transducer always requires drilling a hole in a pipe or opening up the piping to insert a fitting.
Simple recipes Farm tools and mechanisms 22010 lovers of travel. Free online library on electronics. This is detected by the temperature difference between the hot water and cold water supply lines. Directory structure and files are almost identical to the old firmware release v1.
April 1,Latest update: If you wish to modify or extend the PC software, you will also find the source code and information on recompiling eektor code in the download. Follow project Add a comment. The firmware update to version 1. How to download files?
The maximum output level of the inexpensive LM opamps is always approximately 1. In this article we describe a relatively elektof way to check these values and monitor your consumption almost continuously. Alignment and calibration The first task is to adjust the three trimpots that set the voltage thresholds for interrupt trigging. To increase the sensitivity of the system, the return line sensor signals are applied to the inputs of a differential amplifier, and the resulting difference eleotor is amplified.
R47 is necessary to stabilise U4a with a capacitive load. Warning for HHEmu V2. After this the LED should start blinking.
Heating System Monitor (090328)
So, they might have to be entered several times with a change of ECU in between. The author wrote the software for the ATmegaAU boot loader and application program in C, and the source text can also be downloaded. Eelektor executes the firmware in a separate thread and simulates all inputs key presses, timer interrupt, data from DXM module, data from optional Bluetooth module 2100 outputs LCD, data to Elektkr module, data to optional Bluetooth module to make the firmware believe it would run on the AT90CAN Opamp U7d is wired as a comparator and triggers an interrupt in the ATmega microcontroller via pin PB1 when the supply line temperature rises.
Security and alarm systems Car. Car electric circuits Car. Electronic fuel injection Car. A voltmeter connected to the input pins of U6a, U6b or U7d respectively is avrill helpful.
If your OBD2-Analyser NG is equipped with the optional Bluetooth module published in the April issue of the Elektor magazine, you even do not need to flash the new firmware to try it out! Then enter the Bluetooth menu.

The project main page just contains the elektog files for HHEmu V2. The boot loader can be downloaded from the Elektor website  ; alternatively, you can purchase a pre-programmed microcontroller from the Elektor Shop. Heating bills often present unpleasant surprises.
