HVAC heating only doesn't do anything.

I'm trying to simulate a multi-room building with several electric furnaces of a building that is only occupied once a week. To simulate this, I added several electric furnaces (they don't have the same power) and added the related zones to the HVAC systems. Furthermore, I made different thermostat schedules by setting the heating thermostat at 0 degrees C as standard and priority 1 15 degrees celcius every Wednesday (the day is random, just wanted it to run once every week). I set the cooling thermostat standard on 100 degrees C, since there is no cooling done.

When I ran the simulation, I didn't see any noticable difference compared to other days of the week. Even increasing the heating capacity from 2000W to 20,000W didn't make a difference.

The only room that seems to do what it needs to do is the room with also a cooling unit. I did exactly the same thing there as for the other rooms, apart from a more reasonable cooling thermostat ofcourse.

Does anyone know what the problem could be?
