GE RAK180W1 Wireless Thermostat Quest

I recently updated our sunroom with a GE Zoneline PTAC, and also purchased a wireless thermostat for the unit. I’ve read the instruction manual but I am a bit ignorant to understand it. Here are a couple questions I have:

Link to manual

  1. Is there a way to toggle between heat/cool mode? I know that Thermostats are generally controlled by the temperature of the room. In our scenario, we only use the room for short periods of times, and the unit does not run frequently. We’d like to be able to easily power it on, and heat the space using the thermostat but I cannot figure out how to simply turn on heat pump, regardless of thermostat temp. Is there a mode that would allow me to just turn on the heater or AC?

  2. I realize the purpose for the thermostat is to regulate temperate in the room but in our case we’d like to use the ptac to track temperate, and use the wireless thermostat as an on/off switch from another room. Is this possible?

Thanks!

Are you using this custom integration to interface Home Assistant to it?
