I have a Zodiac AquaLink PDA, and when trying to start the heater for the SPA, it does not do anything.
I first turn on the SPA Mode to let the pump run circulating the water in the SPA.
Then I try to turn on the SPA Heater.
I noticed that the remote is not showing ON for the SAP Heater, but instead it is showing ENA.
Reading at other post in this forum I learned that the Heater will become ENABLED if the temperature of the water is >82 degrees, or if the pump is not on. But in my case, none of these 2 conditions are happening. The pump is one and it is circulating thru the SPA, and the water temperature definitively is lower than 82 degrees.
I notice that the PDA is showing the air temperature but it is not showing the SAP Water temperature (it shows --).
What can I do to solve this problem?
