Advice re heating/water timer switches

    We purchased a house in December of last year and I'm trying to improve control of the heating/ hot water system.
    Current setup is Oil fired heating and water. There's an immersion as a backup.
    We also installed 40 solar tubes so that is currently heating most of the water.
    There's a Horstmann CHannelPlus H37XL controller, a thermostat upstairs and downstairs, and all rads other than those in bathrooms have TRVs fitted (duplication, I know).
    The house is 4600 sq ft so obviously the heating costs in winter are expensive, we knew that getting into
    it but my biggest gripe is the timer/ controller.
    It's awkward to program and only offers 3 on/off periods per day.
    Often I'll want one in the morning, one during the day (if someone is at home) one when we get home and then maybe a few later in the evening depending on who's in the house etc.
    The biggest problem I have with it though is that any time it loses power it resets to default.
    For example, I had a tradesman in the house this week and he caused a brief power loss in the house.
    This resulted in the controller resetting and heating plus water coming on for a few hours, a complete waste of oil. Likewise, if I was away on holidays when this happened the system could burn a full tank of oil before I got back.
    For the summer I've temporarily set the two thermostats to a low temp to prevent the heating coming on during the day. I'm not sure there's anything I can do for the water, nor could I use this thermostat reduction as a fix in the winter.
    I would like to replace the controller with something that allows multiple on/off per day and does not lose settings with every power loss. Remote access, while nice, is not a necessity for me.
    I've looked at Nest and Climote but Nest would require multiple units and Climote seems like overkill for the issue I have.
    Does anyone have any advice? Experience anything similar? Would appreciate your input.

    Replace stats with 6 settings per day per zone version. CM707 is one I use. Your TRV's are NOT duplication as these can set a max temperature for rooms when the heating is on thus saving money ie. unoccupied bedrooms etc.can be set to lower setting than the zone stat.
    If power cuts internal battery keeps the settings. Maybe your internal battery is dead.

    Thanks for that.
    Looks like internal battery is dead although the manual says it should be good for 8 months of usage. Either that or it's faulty.

    Will have to replace the unit with something more reliable.
    Cheers.
