In your other post where VRVIII told you how to set auto on your remote controller, I mentioned field code 12-4-01 through 08. Review your service manual on when the controller will switch from cooling to heating and back at the 8 different temp differential settings that can be selected. It will not switch from cool to heat at 22 and 24 but rather at higher temp than 24 and a lower temp than 22. Once switched the system will come on (in cooing or heating as necessary) to bring it to the set temp.

For a 2C* difference between cooling and heating you are going to want setting 03.
