Jandy Versatemp not heating/chilling with Aqualink RS

[Rfoor88]

Hey All,

First post here. Recently completed pool construction. Have Aqualink RS system and Jandy JRT3000R heater/chiller. Went to use the spa last night for the first time. Aqualink worked fine putting the pool in spa mode but it would not trigger the heater to come on. When I went to turn on the heater manual form the control panel it worked fine. The heater has the remote option enabled. Verified its setup with 4 wires connected to Aqualink so it can control heating and cooling. Has anyone experienced this issue? What am I doing wrong here?

Welcome to TFP
I don’t have this type of heater but I do have AquaLink. I read in the manual that that if the RS485 (4 wire) is connected correctly then the display for the heater will read JANDY REMOTE ONLINE. Is this what your display states?
Can you show picture of the display, also, can you show picture of the 4 wire connected to the RED connector on the PCB?

Did you ever get this sorted out? I think I am having the same issue.
