Doubt it. Winnipeg isn't at the North Pole...
It's not much colder there than here in Calgary. Most units set up correctly here will run longer on low with more CPH unless coming off a setback.

some years maybe..last year warm winter ... only -20C
W1 is all that most furnaces need since they are so grossly oversized 90% of the time. Seriously, most furnaces are 2X the size they need. W2 would only be needed during recovery from setback.
Ummm sounds like you need a 2 heat stat
yep I hear ya... probably gonna be be minus 40 all winter this year...we got spoiled last year...
