here is my config yaml for climate. added hint for your case but i never had heat pump, does your heat pump only heat or does it also cool? exemple here is ok if only heat. If yours heat/cool, try some of the hacs thermostat addon.
A quick search led me to this https://community.home-assistant.io/t/generic-thermostat-switch-between-heating-and-cooling/420053
which point to https://github.com/swingerman/ha-dual-smart-thermostat
but i know they are more hacs addon for thermostat, you may need to search which is good for your use if the one above doesn't suit your needs
