You have to go into the pool heater menu and set a temp higher then the water is probably set lower then the current water temp.

Pull the cover off the control panel. You will probably find a button which would be accessible from outside the panel with a paper clip or pencil but is unlabeled. On the board itself by the button, in small letters it should say "reset". Push the button and see what happens.

SOURCE: JVA 2440 rotates continuously in spa mode

If you remove the handel and open thr top of the actuator you will see a set nut on the center of the shaft that you use to set where the valve stops. If this is tight then you may have a bad micro switch in the unit and you should replace the actuator. Good luck.

SOURCE: Jandy aqualink rs8.Pool and spa lights wont come

If it's both lights and they are on seperate switches I would start by checking the GFCI and be sure it is not tripped and if it is you would need to find out why. Then check power in and out of the light module in your power center. If you can set the power center to service and turn the lights on manuley from there then it is programming but most of the time it will be something in the lights or their circut.

I cant move the jandy valve for pool return which means I can't turn filter on because if I do pool drains into spa.

Have you tried using the three way toggle switch on the JVA? It might be in the locked position.
If the JVA is not working you can always move the valve manually until you replace it.
First, put the directional toggle switch in the locked (center) position.
Second, loosen the retaining screw on top of the JVA handle about half way to three quarter out.
Third, push down on retaining screw firmly to disengage JVA.
Fourth, while pushing firmly on retaining screw rotate valve manually with handle to desired position.

I have a Jandy Aqualink pool system. When I turn on the spa and heater, the spa drains..I've never had this happen but don't use the spa much. What should I check?

His is not typically a control panel issue but more likely a valve issue.

Your valves are set as follows wih a few minor variations.....
Pool mode- sucks from pool skimmer and or pool vac line and returns water to both the pool and spa.
Spa mode - self contains the spa , meaning water is sucked from the spa and returned only to the spa.
If your spa is draining then most likely one of your electronic valves is failing...most likely it's the return valve so what is happening is the water is sucked from the spa and returned to the pool instead of self containing the spa.
Easy check is to be next to the equip when spa mode is selected and two valves should move and align properly, the return side valve is most likely not moving or it is not moving into the correct position.
The fix is either adjusting the valve acuator or buying a new valve acuator.
Another thing to check is on the main panel circuit board to ensure the return and auction 3 pin plug ins are still connected.

My controller says it is in spa mode - trying to heat only spa- but water is spilling into pool. I have 2 jandy valves, only 1 moves when I change from spa/pool mode. Any suggestions?

The valve actuator on the suction side is either bad or the toggle switch on the back is in the wrong position. There are 3 positions for the switch on/off/on. It should be in either be all the way up or all the way down. In spa mode move the toggle switch. If it still doesn't move then you have a bad actuator. If it moves someone has moved the switch.

The Spa Mode emptied the spa water into the pool so the pool level is too high and I cant get the spa to refill.

You RETURN side valve actuator has malfunctioned and did not move into the spa return position. Most actuators have a toggle switch on them where you can over ride the system.
The 3 positions are; normal, off, and reverse. You can check to see how the valve is moving by flipping the toggle switch. If the actuator is more than 10-12 years old it may need to be replaced. Actuators are standardized between manufacturers and new ones will run about $120, easy to change out.

System will not switch from pool m ode to spa mode. I use the remote control and it says the spa mode is on but the pool mode continues to function

First check to see if the valves can be operated manually. There are tiny switches on the side, end or underneath of the automated valve actuators that can be switched to operate the valves manually. With the power on and with the switch in the center position the operator should not move. In the other two positions the operator should move the valve to one limit or the other. If you cannot get either operator to function manually this way then there is likely a problem in the control system. If you still have a problem feel free to respond send me the results and I will respond with more things to do. I hope this helps.

Spa won't heat unless in spa mode, and if it is in

On the automated valves there are tiny switches on one end or under the valve actuator. When you switch to the spa mode the suction valve should should move to fully block pool drains. The return valve should fully block the pipes to the pool returns and spa fountain. If one or both of these valves is not fully blocking the pipes to the pool then the tiny switch on that valve is in the wrong position or an operator is defective. The middle position of either of these switches turns the operator completely off so it cannot move. That is the position to avoid unless you want to operate it manually. One of the other switch positions caused the valve to move in one direction and the other switch positions causes the valve to move in the other direction. If you set the switches so when in the spa mode water is circulating only in the spa then you have the valves in the right position. Next, place the system into the pool mode. Both valves should move to the other position. If not then the valve operator that doesn't move has a problem. It could be the operator, the wiring, the control panel or a stuck valve in that order. All of this sounds complicated but once you know how the operators should act when you flip those tiny switches and how the valves should act when in the spa and the pool mode then getting the switches set right is simple. I hope this helps.

Jandy aqualink rs4: pool has been winterized with the spa left on. when switched from service mode into auto mode system switches back from spa into pool mode (motorized valve switches back to pool mode)....

the only thing you can do since the jandy does not have a "winter" mode is switch the valves off. Once you have the valves in spa mode, there should be a toggle switch on the valve actuators. You can set the switches to the middle position and that will lock them in that position. You will probably have to re-winterize the pool lines.

SPA Filter on while Spa is Heating

If it has motorized valves the stop positions have to be adjusted so that the water coming back is equal to what it drains to stop the spill over process unless you want to add more valves but the pool pump does the job of heating and filtering the spa
