Is it a kit or an AG brew more info would be good

It depends on what yeast you are using. Are you using a kit or all grain?

The yeast packet will have the temperature range printed on it.
I've fermented with the Diamond lager yeast at 12 deg then raised to 18 for a few days before lowering to close to zero - tried slow stepped cooling and cold crashing. There's a good write up here of one of the more rapid lager brewing processes which would apply well to the Diamond yeast Lager Method
First time I used this I fiddled with a two step starter. These days I'd just use a couple of packs of dried yeast instead in a single batch.

10-15 C is the declared optimum temperature. There seem to be a number of comparisons with W 34/70, the latter will ferment nicely into the high 20s, but it'll give the beer an ale character rather than a lager one. I suspect Diamond is not dissimilar.
First time using Diamond Lager and I’m very happy. Pitched on Saturday and it’s already time to start upping the temp towards D-rest. Brewing a Helles that’s normally fermented with wy2308, interested to see how it turns out.
This makes me wish I'd got my ispindel working ... I've been a bit intimidated by the setup so far! I've a lager fermenting at 10 deg at the moment and it's 5 days in and still has krausen. I'm a little worried it is infected since it was v slow to start and data like this would have been v reassuring.
On another note, sadly I am really looking forward to the Scottish winter and the opportunity to stack the outside shed with lagers to cold condition for a few months

The real value of an iSpindle is lager brewing. Previously I’d lose a litre of fermenting brew in sampling’s. It’s a game changer!

.iSpindle setup isn’t too bad. I did cover the kitchen floor in sticky sugar liquid during the calibration process. Once that was done I followed the GF setup instructions and surprisingly it worked. My calibration is off, but I just need to know when to D-rest so I use hydrometer readings to provide OG and FG. If I ever calibrate again I’ll do the fast ferment method instead.

Not necessarily - see this on warm-fermenting 34/70 :

For some reason the images don't download for me, but I've preserved them here :

At temperatures from 12-20°C (and some other variables like pitch rate and gravity, the grey one is a big underpitch and the dark purple one an overpitch, which are the two giving significant "OFF Notes")
