I have a heat pump system and a Trane thermo. When AC runs on AUTO with the fan on AUTO the unit immediately freezes up. If I run the fan on ON and AC on AUTO it runs fine.

The AC repair said The thermostat can be programmed to add a delay on the compressor - but he didnít know it and I canít find the setting.

Anyone know how to add a delay before the compressor comes on when running AC on AUTO?
