Fan-only mode for MS-SD24VC #13

Open mweber88 opened 7 years ago

mweber88 commented 7 years ago

This unit (Mitsubishi MS-SD24VC) has a mode called Fan Only, which is not Auto, Heat, Dry, or Cool.

I would like to emulate this mode. Do you know what the byte would be for this mode?

Really, what I want to do is turn on Fan-only mode and control the fan speed of a different Mitsubishi unit. I would like to have faster fan speed than the bare minimum when the temperature is satisfied in Heat mode, but no setting will make that happen. I'm really hopeful that the fan-only mode will allow fan speed selection, and it will work with my Mr. Slim heat pump.

Ideas?

Is other mode works for your AC? If so, I think you can try this:

edit IRremote2.cpp, go to line 426, you can see this:

case HVAC_AUTO: data[6] = (byte) 0x20; break;

add a new line next to line 426:

case HVAC_FAN: data[6] = (byte) 0x00; break;

in HVACDemo.ino, you can use this code to send a FAN mode command:

irsend.sendHvacMitsubishi(HVAC_FAN, 23, FAN_SPEED_1, VANNE_AUTO_MOVE, false);

If it works, cheers. If not, I need a fan mode IR raw dump of your IRremote. Use this code to get one: https://www.analysir.com/blog/?attachment_id=515. (a 38k IR receiver is needed)
