Reefkeeper Lite Question

[maron6977]

Just picked up a used RKL ,got it all setup & started watching YouTube for some info on it . I saw when itemp or ph was displayed , he could hit the enter button & it would display high, low & average. Mine does not do that !!! It looked like his RKL firmware was 2.03 . I updated mine to 2.07 . Just wondering if they changed features with updates or I have to install SL1 module , for that feature to work ???
Thanks Mark
