Heater will not come on.

You need to put a volt meter on the wire that goes from the Aqualink to the heater and verify that it is telling the heater to turn on. Then we can determine if it an issue with the Aqualink or the heat pump. Make sure that the water temp sensor on the AL is reading actual temp. Sometimes they will read incorrectly and, for example, display that the water is 142 degrees. If the AL thinks the water is already at or above temperature it will not close the switch for the heater to start.

All you have to do is put your Aqualink in series with the heater's safety loop. Sometimes there is a terminal block, but regardless if you can find the pressure switch, cut one of the wires and connect the wires from the Aqualink to each side. (There are two ports on the top of the Aqualink power center board designated for this)

At that point the AL is in control of the heater. Make sure that the heater is powered up, turned on, and your thermostat is set to max.The AL will turn the heater on and off following your programmed temperature setting.

I have an Aqualink system, spa set to 104, it will heat to 94 and stay there, temp sensor is working, took water sensor out of line, plugged line, assumed heater would just keep heating, it did heat a

The heater may be wired just fine. The aqualink uses its water temp sensor to call for heat based on what you've set the thermostat to on the aqualink. However, most heaters have built in thermostats that over-ride the aqualink. Those thermostats come factory defaulted not to go over 94. Check your heaters manual on how to adjust the thermostat on the heater. Your heater should have its thermostats set to 104 and the aqualink will control the actual temp of the water by calling for heat based on what you've set the thermostat on the aqualink for. Hope this helps.

Aqualink reads " water temp short " . Is this a

This code menad that the water temperature sensor has gone bad. These will cost around $60-80 retail, unless you buy Jandy OEM, then you will be paying well over a $100.00. But you can also use a Jandy, Goldline, or Pentair sensor and it is a fairly simple repair.

My spa will not heat. The heater shows that it's working but it will not heat the water.

When you say that the heater shows that it is working is it the heater that shows this or the Aqualink. If it is the aqualink it could be a temp sensor, probally the water sensor that is in a pipe comeing from the pump. But the first thing Iwant to think of is your temp is set on the Aqualink but the temp is not turned up on the heater. If your heater is not compatiable with the link you need to keep the thermostat at max and set to pool or spa to have it work. If it is compatiable it could be in the wireing between the two or you just may need to be sure the Aqualink is set to read and override the heater. Your menu can walk you through this or your book on the unit. Let me know how you do and we can check for further problems in your heater. If so let me know brand and model of same. Good luck.
