normally most systems can reverse the flow of refrigerant to act for heating but in e-heat mode the system is pushing heat in by its own internal fan only in normal heat mode however the system may take a while to adjust and turn on but as stated in e-heat mode it may only push heat in by its own internal fan some systems may do this

Mitsubishi electric Mr Slim wall unit heat and air. strange smell coming out when air is on, we cleaned filters, but do not know where the heat exchange is or the the fan to clean them
Ductless split systems are know for creating a mildew looking "stuff" on the blower wheel. Try to open/move the louvers on the front of the indoor unit. By opening the "osculation blade"/louvers, you can see the blower wheel, normally blue in color. See if it has some mildew growing on it. If so, I found that a tooth brush and about 2 hrs labor does some good. I've found some aerosol spray, called mildew removal. Works great at covering up/controlling the smell. It's also possible that the unit is pulling air from the condensation drain line. These lines can for algae, and give us a sour yuck smell. To clean, use a wet vacuum, and clean from the outlet of the drain line. Hope this helps!

Mitsubishi City Multi VRV unit fault code 2502
2502 code indicates float switch issue. Try taking a wet vac to the outlet of the drain line and cleaning it by vacuuming the outlet. This will clear the drain line if it's not tied in with multiple drains, but may not clear the code. To clear, try tuning off breaker(s), wait 10 mins, then turning breakers back on. If this doesn't help then there is an issue with the float switch or the control board. Float switch is supposed to prevent the drain from over flowing and is normally located in the condensate pan, but I don't advise anything else, other than cleaning the drain line and resetting the system.
