    hi
    just started on t-slim-x2 and control-iq and after 2 days just about it got stuck at around 12 4am then bounce around 11-13 for a 4-6 hours then change insulin site and cartridge and it's still doing the same. normally on the prevoius medtronic 640 i'd just stick a temp basal of 1.8 units for 3hours and it would kick my body back into action but control-iq does not seem to have that functionally i'm in constant variable pain and and maybe my liver sensors get stuck at liking some lv of bg and try to keep it at that level. bolus's and small changes in basal do not seem to effect it. any ideas?

    Hi @Angusc many have found that basal levels from other pumps to not work well when moving to t:slim, I had to modify my basal levels. You have to turn control IQ off if you want to use temp basal. For illness many of us have set up another profile with % different basal levels (20%, 50% .....) this way you can move to another profile but still keep CIQ operating.

    As @Chas C says you have the option of switching off Control IQ to use a temp basal.
    Within Control IQ you can do a 2 hour extended bolus which can act like a temp basal.
    i.e. if your current basal is 1.0 units/hour then an extended basal of 2 units over 2 hours would double your basal for 2 hours. (Use 0% delivered now & 100% over 2 hours) Sounds complicated but it really isn't & you don't have to remember to switch Control IQ back on.

    If you switch off control iq you can set a temp basal

    Another way is to do an extended Bolus 1% now rest over 2 hours

    Sounds if it’s consistent that you need to tweak your basal rates slightly. Just because you have the same rate for a previous pump doesn’t mean it’s correct for this one

    It took me a few weeks of tweaking to get good control

    I also found increasing the maximum hourly basal limit helped so that control iq had more freedom to increase the basal rate

    So much more simple than a t:slim temp basal or other profile :)

    i doubt it basal as it a very steep rise from a flat line and is unaffected by bolus's and not time dependant. so unpredictable :( only happened 3 times so far

    Hi @Angusc

    Are you aware of the dawn phenomenon - where BG's rise in the early morning, for most of us its anywhere between 4am and 8am. My basal has to rise from around 2am to cover it and it rises in my own case by 50% before falling back to my average level. Its the main reason I choose to move to a pump because I could not control it via injections.

    Apologies I'd missed it was random, I'm just about to change from 6mm to 9mm Autosofts due to similar issue I've been seeing.
