Release Notes 5.4.0CD

New Feature – Controller Enabled setting

This setting will prevent the controller from ever turning the pump on. Useful if you are going away and are turning off your water and concerned about the controller accidentally turning on.

New Feature – Erase Log advanced setting

Some firmware releases like this one require the log to be erased. This is normally accomplished when the firmware is installed. However, if the version requiring the log to be erased is not installed and a subsequent firmware version is released, the subsequent firmware update may not erase the log. This allows that issue to be easily resolved.

New Feature – Reboot Controller advanced setting

This is useful if your controller is installed in a location that is not easily accessible and there is an issue requiring rebooting.

New Feature – Debug data in log file

A byte of debug data was added to the log file to help our engineers diagnose issues when the controller misbehaves.

Release Notes 5.3.3CD

Bug Fix

Fix issue which caused the LED to not turn red during provisioning mode when the controller is triggered as described in the system test in the Quick Start Guide.

Release Notes 5.3.2CD

Bug Fix

Fix issue with naming a controller something longer than 19 characters.

Release Notes 5.3.1CD

New Feature – Custom Controller Name

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.

New Feature – Set Password on Controller

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.

Release Notes 5.2.1CD

Bug Fixes

Fix bug that sometimes caused timers to not be stored.

Release Notes 5.2.0CD

Remove Pulse Filter

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.

Release Notes 5.1.1CD

Updated Log File

This firmware updates the data stored in the log to include the flow value that triggered the run event. 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.

Release Notes 5.1.0CD

Pulse Filter

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.

Pump Run Time

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.

Release Notes 5.0.6CD

Auto Disabling Timers

The firmware was updated to correctly re-enable timers that had been automatically disabled by the “Smart Timer”TM feature.
