Redline Controller In Canadian Winters

Hi I am in the process of making a major update to my “vintage” 2022 1F Journeyman CNC with BB Controller and the 10” Touch Screen. My question is this. Given I live in Canada (NS) it gets really cold in the winter times (not as cold as the prairies) the Redline Spec’s state an operating temperature of between 5C to 45C but gives no reference to storage temperatures it can get as cold as -20C (maybe 2 to 3 days a year) but winter temps can hover between -5C to 15C for days at a time, will the Redline Controller be OK with those being my cold storage temps? I do heat my shop before using my 1F in winter with a diesel heater usually up to 8C - 10C which is plenty warm for me and is within both BB and Redlines operating temperatures.
