Thermostat wiring


Can anyone help me to wire this new thermostat for my heat pump. The first picture is my current thermostat from 2002. The second picture is the wiring diagram for the new thermostat. The third picture is the new thermostat I would like to install. Thank you

Why would you get that crappy thermostat for a heat pump? You should have gone full digital so it switches between heat and cool as needed without flicking a stupid switch. Take it back and get a good one.

Dude…that’s not a heat pump thermostat…

Thank you. I will be returning this one.
