Hello all. I recently acquired a pentair intellicenter. I have a heat pump I’m trying to wire in. I’m assuming the heater will go straight to the breaker so it has constant power but what I’m confused about is the diagram on the door shows electric heater next to the aux ports and below the gas heater connection. It’s a 2 wire with a plug. Bit there is no plug to that port. Is this a special wire I need to get or do I run it through a relay.
