I just bought and installed the Janda PDA P4. I got everything working EXCEPT the spa. My PDA doesn't show an option for the spa mode. I am able to switch to spa mode at the board by the pool pump when in service mode.
Here is my setup:
1 pump to circulate the pool and spa
1 pump for the waterfall
1 blower for spa bubbles
gas heater (currently broken with a rusted off igniter bracket)
electric heater (no in use)
I was told by Jandy/Zodiac that i need the PS4 to be able to control the spa from the PDA. Is this true? I am reading contradicting stuff elsewhere.
