Intellicenter + Gas Heater + Heat Pump

Hey all, I had a question regarding having both a gas heater and heat pump connected to the Intellicenter.

I have my Raypak 406A gas heater connected to the fireman's switch. I also have a Raypak 8450 heat pump that I cannot figure out how to control via Intellicenter. Someone told me you can connect it to the Solar 485 connections, which seems to get me no where. I even popped a resistor into the solar temp sensor terminals.

Gas heater works fine, but can't for the life of me figure out the automation control to also add the heat pump. Is there any way to do this? I ideally want it to prefer using the heat pump and use the gas heater for the spa or when necessary.

Thanks!
 
The IntelliCenter can control a gas heater connected by firemans's switch or RS-485 and a Pentair UltraTemp Heat Pump connected by RS-485. The UltraTemp HP is the only one so far that reliably connected using RS-485.

I don't see any RS-485 automation support in the Raypak 8450.
