Hi,
If I get a Pentair Heat Pump Cooler, which AFAIK has a RS485 connection which can be used with a PL4 with ScreenLogic, in order to be able to control the Heatpump from the Pentair app, does the Heat Pump need to use a relay from the PL4, or can it be plugged without the relay, but connected to the RS485? I want to understand if I will be short in relays and need to upgrade to a PL8, or if I can use it only with the RS485 connection and no relay.
If what I'm asking doesn't make sense, I apologize, I'm new in all this.
Thanks
