Aqualink schedule for filter pump only, yet heater turns on too

[ms.claudiao]

I have a in-ground spa that operates with a Jandy Heater, Jandy filter pump and Jandy booster pump. We use the Aqualink system with the app for Aqualink on our iPhones. The remote that comes with it works, but we rarely use it.
There is one item on the schedule and that is the filter pump to run everyday for 2 hours, 2 p.m.-4 p.m.
The problem is as of recently when the filter pump turns on during its scheduled time the heater now comes on as well. The heater is not listed on the schedule.
We have turned off and then on everything at the power box. We deleted the schedule and then re-entered it. Yet the heater keeps automatically coming on during this scheduled filter pump time.
Any advice is appreciated.

What model heater are we discussing?

@HermanTX @MSchutzer @PoolGate should be able to help you turn off the heater in the iAqualink app.

What does your speed setup look like? Is anything on your "Assign to Aux" column? Also can you post a pic of you schedule?

Good morning!
The heater is Jandy JX1400N. I noticed that as per usual, the CHECK FLOW SET message is present. Usually when this is the message, adding water does the trick and the message disappears. Based upon your question though, I did a quick search and am wondering, if there is more to that message?

Since you are seeing a check flow message on your heater display I'm wondering if your heater is even connected to your automation system. Do you have any control of your heater on it's control panel? If the heater is connected via the RS-485 remote connection as it should be (you have all Jandy equipment) then the heater control panel should not be functional. I wouldn't expect that you should see a check flow message if it was in remote operation as the Jandy RS panel would not be trying to turn it on when the pump is off.

It's sounding like the heater is in local heater control, and you have it set to have the heat on. You see the "check flow" message when the pump is off because the heater is disabled because of no flow, and when the pump turns on the heater turns on.

I would check that you have a good connection on the 4-wire RS485 connection between the RS main panel and the heater. If that connection is bad, or unplugged, then the heater would revert to panel control, and it seems that the heater control panel has the heating function enabled.

That would explain why it is heating with out any heat being scheduled or enabled on your Aqualink system.

This sounds like it is the issue. Your heater should be in remote mode. Go through the menu and set it to remote mode.

Another thought, I have a much older Jandy / Laars LX400 heater and mine will drop out of remote mode if the heater has any faults. I turn the external gas shutoff valve off when I'm not going to be using the heater for a while (it's only used for the spa) and if I forget to turn the gas back on I will get a AGS fault and the heater drops out of remote mode due to the error. I have to cycle power to the heater, or press the remote button to get it back in remote control mode.

If your "low water flow" condition was real and not due to the pump being off, that could have triggered the remote control of the heater to revert back to manual, assuming the JXI behaves like the older LX heater model. In any case put it back in remote mode as @PoolGate suggested.

I have that heater and it has never dropped out of remote mode. And I have had errors. Mostly IGN errors but it always is in remote mode.
