Thermostat Delayed OFF (on close)

quick one…

I had a problem the other day when 1 of the channels was stuck and the AC continued to blast even after reaching setpoint temperature… hence the following question

When I set the thermostat to “StandBy/Frost” (x) I want to also send a full OFF to the units

But when I send the OFF signal - I want the FAN to continue for 1 minute or so to remove excessive cooling (and moist)… but I don’t see a “Delayed OFF on close” – I could use a virtual channel - but perhaps it would be nice to have this in there directly… ?

There may be a possibility with action 0505. Delayed off only when subject is on, otherwise you may have to use a virtual channel.
