The only way to see if the Heat Pump is set up properly to heat and cool is to operate the t-stat.
Check the t-stat to see if it has an emergency heat mode.
Check to see if there is a forced air furnace in the home.
If so, put the t-stat in emergency heat mode & turn the t-stat to 10
degrees above room temp.
The furnace should come on. If not, good chance it is not wired
properly for aux. heat
Put t-stat in cooling mode & turn temp down 10 deg below room temp.
Sometimes there is a 5 min delay between modes. If
compressor starts all is well on cooling side.
Now, put t-stat in heating mode & set temp to 10 degrees above room
temp. Unit should reverse to heating, May be a time delay.
