A logging feature has been added to the Smart Recirculation Control and the Smart Recirculation Upgrade (sorry, it is not yet available in the Smart Recirculation Retrofit). This feature is available in firmware version 1.5 and later. To access the log, run the app and connect to the Smart Recirculation Control. Select the menu button in the upper right corner of the app and choose "Log" from the menu.
If you have the Smart Recirculation Control the log will provide you with the On and Off date and time and the respective high and low temperatures and the total run time. A total of 53 On/Off event pairs are recorded in a rolling window.
If you have the Smart Recirculation Upgrade it will provide you with the On and Off date and time and the total run time. The temperatures are unavailable as this controller doesn't use the temperature sensors to turn the pump on and off but instead uses the flow to know when to turn the pump off. The temperature of the water in the hot water line is controlled by the thermostatic cross over valve and is restricted to a maximum of 104 deg F by Uniform Plumbing Code. A total of 79 On/Off event pairs are recorded in a rolling window. There are more logs available in the Smart Recirculation Upgrade because there is less information recorded per event.
If you don't see "Log" in the menu then your firmware is lower than 1.5. To see the exact version select F.A.Q. from the menu while connected and the firmware version will be listed. If you would like to have your firmware updated so you can access the logging feature please contact us and we can arrange for you to send your controller in to be upgraded. There is no charge for this other than the actual shipping costs. If the firmware version is listed as "unknown" the app is not connected to the controller.
