    Default Two Zones Created Their Own Manual Timers

    I have no optimization enabled and thus was surprised that I could hear the heating was on. It was about 06:30 and nothing should come on till 07:30.
    At first I thought it may be the update gone funny but box still on V1.

    Anyway two Zones were on because according to the display and app that manual on temperatures had been set ending at 07:30

    No such events were set by me.

    Anyone else seen this?

    Once up I will post a screen dump, still in bed

    Are you sure that the actual temperatures in the two zones didn't fall below the target temperatures?

    Up now
    The zones are all set to 10c during the night increasing to various settings at 07:30

    The two zones that did it were the Kitchen, picking 19.0c and the Hallway picking 16.0c

    I then used the app to turn two more zones on and the evohome you will note shows the two different symbols

    After 07:30, back to schedule

    I hope the photos are in the right order.

    Looking at the middle photo, the Kitchen and Hallway appear to be over-rides set on the controller. Are all your zones configured to turn off/turn down temperature at the same time? I ask because there have been issues in the past when the controller has failed to re-set an over-ride when the next time point is reached. The other symbol is a phone/Pad icon.

    Hi, yes it does sound like the second thread.
    http://www.automatedhome.co.uk/vbull...antom-override

    The kitchen zone temperature is controlled by the wall thermostat option rather than the HR92.

    The hall zone uses the HR92 sensor and no one touched any of the devices.

    I shall keep an eye on it and may even refit the timer in the boiler so it can't run when the heating should be off.

    The best workaround for this problem is to remove the batteries for the HR92's in the affected zones, then reinsert them after a random amount of time.

    This will randomise the timing of the hourly set point reports the HR92's send (which causes this phantom override issue) in relation to your schedule, and as the window of vulnerability is very small (only a few minutes) 9 out of 10 times rebooting the HR92's will solve it.

    I too have recently had these. I have only HR80s around the house and two or three times the schedule overrides have shown when none were entered.

    The clue to this problem is that within about 3-4 minutes after a zone is scheduled to change to a new temperature it will revert to the previous set temperature but with the manual override hourglass displayed, as if the user had overridden it back to the previous temperature.

    Indeed, your clue seems to be correct.
    I have not tried the battery removal yet but will do that later today.

    And yes, the Kitchen zone did it again, setting it to the night time temperature, 10c for the full day (up to 22:30).

    I trust a fix for this bug is also included in the new firmware being rolled out...
