Fix issue with naming a controller something longer than 19 characters.
Fix issue whereby the controller could not be connected to without explicitly setting the controller name during the provisioning period.
The ability to set a custom controller name has been implemented. The default controller name is “SmartCirc” and if you only have a single controller and are not operating in a multi-controller environment you can leave the controller name as the default and the app will connect as normal.
Once connected the controller name can be changed by navigating to Settings→Advanced Settings→Controller Name and entering a custom name. Once the name is set, the app will attempt to connect to the controller with this name in the future. If a controller with this name is not found it will prompt for the controller to which to connect. The app can be configured to always prompt for the controller by turning on Settings→Advanced Settings→Prompt For Device.
The ability to set a password on the controller has been implemented. If the controller is operating in a multi-controller environment the password can be set to prevent unauthorized access to the controller.
By default there is no password, but once connected the password can be set by navigating to Settings→Advanced Settings→Controller Password. The controller will remember the password and attempt to authorize when connecting. If successful it will connect, otherwise it will prompt for the password.
If the password is forgotten, the controller can be put into “provisioning mode” by unplugging it, waiting 5 seconds and then plugging it back in. For the first thirty seconds it will advertise the default name “SmartCirc” and not require a password. Connecting during this time will allow the name and password to be configured. During provisioning mode the green led will blink steady on and off every second.
Fix bug that sometimes caused timers to not be stored. Fixed temp sensor driver bug.
The minimum temperature value registered at the temperature sensor after one minute of run time was decreased back to 95F as we were having reports of controllers erroneously turning off with the setting at 104F.
This firmware removes the pulse filter and replaces it with a better algorithm that prevents false triggers by averaging the flow to eliminate high frequency pulses from the pulse count.
This firmware restructures the task that obtains the temperature from the temperature sensors.
The temperature sensor driver was updated to be more fault tolerant of intermittant connection issues.
The minimum temperature value registered at the temperature sensor after one minute of run time was increased to 104F, the temperature at which the thermostatic valve is guaranteed to be fully closed.
This firmware updates the data stored in the log to include the flow value that triggered the run event and the flow value when the pump turns off. If the flow value is 0 then the event was triggered via a timer.
This update requires that the non-volatile memory be reinitialized because the log record size has changed. This will reset any custom settings back to factory default values so be sure to record any timer or setting modification you have made before performing the update. The current log will also be erased.
There are instances when the controller may trigger when no one is actively drawing hot water and this feature was added to address this issue. This feature is available via “Settings→Advanced Settings”. It is disabled by default but if you are experiencing these issues and have increased your sensitivity setting in an attempt to prevent this, you can try enabling this feature and setting the sensitivity back to the default of 20 and see if this resolves the issue.
Before changing the default setting of 19 ms please read the Technical Details.
The controller is normally turned off by sensing the temperature difference, but if there is a failure with one of the sensors, like a temperature sensor has come loose from the piping, the controller would continue to run indefinitely. The “Maximum Pump Run Time” will turn the controller off at a default of 15 minutes. This can be adjusted via “Settings→Max Pump Run Time” from 1 to 30 minutes.
If the “Max Pump Run Time” has been exceeded the controller will blink the red led every 5 seconds instead of the green led every 10 seconds and the smartphone app will display “Run Time Exceeded” on the “Live Data” screen. This will be reset when the controller is triggered for another cycle.
The current pump run time has been added as a value to the “Live Data” screen and is displayed for 10 seconds after the pump turns off.
If the controller has an error communicating with a temperature sensor the controller will flash the red LED, turn the pump off, AND disable the controller until the issue is resolved and the controller reset. Previously it would flash the red LED and turn the pump off, but there have been instances where the sensor error was intermittent causing the controller to toggle on and off rapidly.
This feature is delayed for one hour after plugging the controller in so that during installation you can adjust the temperature sensors without the controller getting disabled. During this time the controller will blink the red LED and turn the pump off but will not disable the controller.
Temperature sensor errors can normally be resolved by inspecting the Y connector where the temperature sensors connect and ensuring the pins are not pushed to one side or the other. If they are you can straighten them with a small screwdriver or pen knife. If they are not visibly bent it can help to wiggle the RJ-14 connector as you insert them to ensure the pins drop into the slot in the connector and make solid contact.
If the controller becomes disabled it can be re-enabled by connecting with the smartphone app and pressing the “Trigger Pump” button. If there is a temp sensor error the smartphone app will display “Temp Sensor Error” on the “Live Data” screen.
The firmware was updated to correctly re-enable timers that had been automatically disabled by the “Smart Timer”TM feature.
