Setting up UltraTemp heatpump to an EasyTouch PL4

Abilene, TX

Has anyone connected an UltraTemp Heatpump to an EasyTocuh PL4 controller? Easytouch is working good. It controls my VS pump. Heatpump is connected via RS-486 connection to the com port as identified in the manual. The easytouch recognizes the heatpump is installed and the heatpump seems to register the signal from the easytouch with the "heartbeat" icon on the display panel. Problem being is that heater controls on the easytouch have no effect on the heatpump.

I have the water temp installed and the air temp installed. What am I missing? Has anyone tried this equipment setup before?

thanks for your help.
