Network OWL 18:41, Today 2002828Possible fault with the hot water tank temperature sensor. The heating has been stopped because the hot water temperature was not increasing as expected. The temperature sensor may have become detached from the hot water tank. 0 John Holloway1 07 February 2015 19:00 See my above suggestion about moving the sensor up towards the top of the tank, this does work! 0 Stefanl69 08 February 2015 17:25 Thanks John, it is at the top of the tank already, I believe they put it on the pipe as the tank has a jacket and they weren't prepared to cut out a section to attach the sensor to it. It is now also saying the battery is very low and there is no wi-fi signal? This was only installed Friday 0 Steve Baxter 09 February 2015 11:39 OWL resolved mine with a firmware upgrade to the tank sensor and you also need to check that the wire from the temperature sensor is firmly connected to the baseplate in the tank sensor. 0 Jnd67 07 August 2016 08:15 I have been having problems on and off with tank sensor but I do not know what it is so that I can move it???
