EDIT - Thanks everyone. I was able to get the dip switches set correctly and learned how heat pumps operate. I now will keep the pool temp setting below the pool temp unless I want the pool heated. Then I can switch to spa mode and click on spa heater which will use the spa temp setting and heat it up on demand.

Hello,

I just had this new full Jandy automation system setup. When I go into the app and click "Spa Heat" and "Spa Mode", the app says standby then heating, however the heat pump is never turned on so the heater never actually works. I have to go into the web app, turn on the heat pump via other devices, then it will heat. Once I turn off Spa Mode and Spa Heat, the heat pump does not turn off, also the pumps speed does not go down to the proper setting, it stays on 2750 which is the Heat Pump speed setting. Im thinking this is some setting I cant find, any help on sorting this out? I posted a photo of the Aqualink wiring and toggles for reference. Im not confident the installer really set everything up correctly, and he's not responsive.

I have the following equipment hooked up;

- Aqualink RS, Wifi
- 2 Auto valves
- Versatemp Heat/Chill Pump Heater JRT3000R
- Truclear salt chlorinator
- VSFloPro 2.7
- 4 LED Lights

Thanks for any help

The first thing that I would check is the DIP switch settings on main panel RS board. See below:
DIP switch 1 position 8 tells the system whether you have a Gas heater, or a heat pump. Verify that S1 position 8 is on. Also set S2 position 1 to on as that sets the system for heat pump priority.

You also want to set S1 position 7 to on as that tells the system that you have Solar Heat, or a Heat pump in the system. This switch setting in combination with the setting of S1 position 8 and S2 position 1 cause the Variable Speed pump setting 7 to get relabeled from Speed 7 to Heat Pump.

I went back and looked at your photo and it looks like S1 - 7 and S1 - 8 are off and those are the incorrect positions for a heat pump. Your system switches are set to tell the Aqualink system that you have a Gas heater which is probably what is trying to be activated when you go into the Spa mode rather than the heat pump that you actually have.

Change the positions of S1-7, and S1-8, move the switch positions to on (to the right) and see if that fixes your issue.

Thanks so much. I will give that a try.

I did flip those two dip switches to on. It doesn’t seem like anything has changed within the system. After, I tried turning on SPA MODE first within the app, then I turn on SPA HEATER, like usual. Unfortunately the same thing seems to be happening, no heat pump activation. It will change to spa mode, the pump speed increases, but no heat pump.

I double checked the 4 wire cable going to the heater and it’s hooked up correctly. The heater screen shows Jandy Remote Online, and I’m able to turn it on/off within the app. So it seems to be properly hooked up.

I also found a setting inside the web app called “HP Priority”, should that be set to enabled or disabled?

Anything else to try? Thanks
 
Ive just discovered the "pool equipment setup guy" came out and added a temp sensor thats plugged into the solar temp sensor spot. This makes me think hes set this heat pump up as some solar type thing. Why would I have a solar temp sensor without a solar system?

Im about to reset everything and set it up myself.
 
Did you power the Aqualink system off and on before and after you changed the dip switches?

Pentair EasyTouch and IntelliCenter systems require a solar temperature sensor to control a Heat Pump. Jandy Aqualink systems do not. But having the solar sensor will not hurt anything.

I am not sure if I powered everything off before I flipped the dip switches, but I have since done a power on/off cycle while testing the system.

I was reading in the Aqualink RS manual and it talks about pool heaters, heat pumps, and solar heaters - all having different setups. It made me think maybe the heat pump was setup as a solar pump or something since its not working correctly.

I read the manual of the Versatemp heater and it says to set the REMOTE setting to REMOTE TSAT, which I did. It was set to REMOTE OFF before I started messing with it.

It seems to me the install/setup is incorrect within the settings somewhere.
 
Make a warranty claim with Jandy.

Have the installer call Jandy Support with you on the line.

Since the HP has never worked since install it is Jandys problem to fix.

Yes, I will have to do that, I was hoping to get it sorted over the weekend as everyone is closed. The pool startup guy whos supposed to set all this stuff up did a half Rear job, so Im not going to bother with him anymore. Ill have Jandys warranty people do it.

If you can turn the HP on using the web app then the Aqualink is communicating with the HP.

Heat pumps are designed to be always ON and to maintain a water temperature. You do not turn a HP ON and OFF as you do a gas heater that heats on demand.

If you do not want your HP to run and heat then you lower the water temperature set point and the HP will not run until it needs to maintain that temperature.

Turning the HP ON or OFF is a maintenance event and why it is in the Other Devices menu.

I think your HP may be operating as Jandy intended it to although it may not be what you expected.

If the HP responds when you adjust the water temperature set point up or down and can be forced off with Other Devices then I think it is working normally.

You may be right, Let me think about that.

How would it work with the chiller? Wouldn’t it always be heating or cooling? What would be the point of the spa heat and pool heat buttons?

Also, when I have the HP on, it raises the VSP speed up to 2750, which never seems to change.

Now I’m confused hah

There should be a dead band of temperatures where the HP does not heat or cool.

Will your HP automatically switch from HEAT to COOL or do you need to select the operating mode?

Pentair had the problem with their UltraTemp HP that it would automatically switch between HEAT and COOL and they were burning up with the cycling. It took some firmware updates to fix.

I don’t know exactly how your Jandy HP behaves with the Aqualink.

I think you select the operating mode but not sure.

I think that is a legacy from gas heaters. Heat pump controls were stapled onto an existing Aqualink system. And then heat pumps became heaters/chillers. It has been a moving target for the automation to update its UI for the changes.

Jandy has the problem of the Aqualink not having OTA updates. So they cannot easily improve the way things work.

It’s Jandy fault.

Let’s agree on some terminology…

The HP can be ON or OFF. When OFF the HP will not run regardless of water temperature.

The HP can be HEATING when the HP is ON in HEAT mode and water temperature is less then the Aqualink setpoint.

The HP can be COOLING when the HP is ON in COOL mode and water temperature is greater then the Aqualink setpoint.

The HP can be in IDLE when the Aqualink set point is satisfied and it is not HEATING or COOLING.

So when you say the HP is ON we need to know which state is it in? HEATING? COOLING? Or IDLE?

The Aqualink should keep the VS pump at 2750 when HEATING or COOLING and not when IDLE.

Set the temperature setpoint way below the water temperature in HEATING mode and see if the pump speed drops down.

Why do you need 2750 rpm? What is the slowest speed that engages the HP?

Read pages 20 & 21 in

Note the different modes the HP can be set to and some of them say “If connected to an Aqualink…”. I think you need to put the HP into the mode you want the HP to operate in.

The HP will not switch automatically and you cannot set the HP mode through the Aqualink.

Thanks so much. I will look into all of this now. Its as clear as mud haha.
 
If you do not have a temp gauge because he used the solar temp leads, I believe this is your problem. In this case you should be getting "open" or something like that for the temp on the screen. Swap the solar over to the regular lead. You need both a water temp and air temp for the heater to work.

Also the temp settings on the main screen use keywords on the VSP speed setup. If those were changed, your heater might also exhibit the same behavior.
