Is there any way to tell what functions are set on the Fujitsu mini-split with the remote controller? 

The indoor temperature is several degrees below the set temperature and the unit is idling along, putting out very little heat.  Pushing the powerful button does produce plenty of heat but I should not have to do that on a day when it is 32 degrees outside. 

I am wondering whether  perhaps a temperature correction was entered or maybe it is set for high insulation and that delays things when the thermostat is turned up?  So my question is whether there is a way to tell what function settings are currently set.
