Raypak heater with Jandy iAqualink

[saxman]

Hi, digging up an old thread here. I replaced our Jandy LXI400 with a raypak. We have an aqualink system in use currently. The raypak heater has a blue, orange, and orange/black wire on it. The RS485 terminal on the iaqualink has four wires, R, BK, Y, GR. Which wires on the iaqualink get connected to the three "remote" wires on the raypak. According to Jandy, terminal 1 or R is 15+ volts, 2 and 3 or BK and Y are data, and GR is ground.

Thanks.

Welcome to TFP.

What model Raypak heater are we discussing?

I don’t think any Raypak heater can be controlled by RS-485 with Aqualink.

You need to use the 2-wire fireman’s switch control.

If you have a standard RayPak heater, it is controlled by the "heater", low voltage relay on the board of the Jandy and either the black/orange and blue wires (using the "Pool" temperature setting) or the orange and black wires (using the "Spa" temperature setting) and following the instructions in this video. In either case, you set the heater for 104 degrees and allow the Jandy to control the temperature.

I am pretty sure that this is correct, but it is SO lame that this is the case in 2024 when smart functionality is so inexpensive.
