gb79126/webasto-v4@4.2.4
Controller for the webasto thermotop C diesel coolant heater ECU (also applicable to the chinese knock offs) , a modified version of the Webastardo board originally designed by Simon Raffrey that runs on arduino IDE written code.
It handles the various procedures for starting up, pid combustion manager to reach and maintain a set coolant temperature and shutting down sequence, as well as various safety, alarms, standby, information display and input via rotary encoder.
At the moment is missing BLE functionality to use a phone app to control it remotely.
| Node | Description |
|---|---|
| ventilate-priming-ignition | manages the stove start-up sequence. it begins with a 1 sec delay to give the program time to reset various external processes when in loop mode |
| 20x4-split-lcd | splits a 20x4 lcd screen in two columns |
| webasto-info-display | handles the the sensor, input data and alarm messages on the split 20x4 lcd i2c display |
| webasto-water-thermistor | No description |
| endurance-calculator | Calculates endurance based on the fuel level and fuel pump rate.
Outpus an alarm when time left is less than the specified reserve time value |
| test | blank patch used for testing
|
| ventilate-priming-ignition-loop-run | No description |
| programselector-v4 | cycles through the different stages of the stove operation. Outputs value for the enablers, and various interlock conditions, keeps track of failed ignition attempts
|
| fails-message | used in the ignition procedure outputs a fail message if flame is not detected at the end of ignition |
| standby-stop-v4 | No description |
| nth-output | No description |
| seconds-to-dhms | Converts seconds to days, hours, minutes and seconds for the endurance calculator
|
| average-level-calculator | smooths out the tank level sensor output by calculating the average over the last 10 seconds taking one reading per second |
| active-alarmi-nterlock | prevents a pulse from going through if any of the input condition is true |
| ble-comms | No description |
| bluetooth | No description |
| failed-ignition-manager | keeps track of how many times the stove fails to ignite and triggers the restart procedure. Max number of failures must be specified, the counter reset when flame is detected |
| ventilate-priming-ignition-loop-run-copy | No description |
| ventilate-priming-ignition-loop-run-copy2 | handles the stove starting |
| programselector-v4-copy2 | cycles through the different stages of the stove operation. Outputs value for the enablers, and various interlock conditions, keeps track of failed ignition attempts,. UPDATED TO BE TESTED
|
| push-button-manager | Outputs start and stop pulses by holding the switch pressed for 2 seconds.
Outputs the reset pulse by pressing the switch 5 times in 2 seconds |
| encoder-switch-manager | Combines mapped min-max rotary encoder function with multifunction switch pressing behaviour |
| programselector-v4-1 | cycles through the different stages of the stove operation. Outputs value for the enablers, and various interlock conditions, keeps track of failed ignition attempts,. UPDATED TO BE TESTED |
| not-equal-to | outputs true if input values are different from each other
|
| main-controller-v4-1 | main patch of the stove controller updated, to be tested |
| main-controller-v4 | main patch of the stove controller
|
| peripherals-handler | enables/disables the various peripheral according to the idx output of the program selector |
| idx-handler-fuel-pump | manages the fuel pump rate setting at the different stages of operation, based in the idx output of the program selector |
| idx-handler-fan-speed | manages the fan speed setting at the different stages of operation, based in the idx output of the program selector |
| fan-fuel-idxer-copy | manages the fuel pump rate and fan speed setting at the different stages of operation, based in the idx output of the program selector |
