Response to Hello Mercedes, The owners manual we have only shows installation. Jandy Owners Manual . Sounds like the remote is in working order. Do you know what type of heater you have is it Gas or Electric. When you push the button for Heater it will not be instant it has to turn heater on and actuate the correct valves. Then will take awhile depending on tempature of spa. Check to see if your heater is even working. There should be lights on your heater that indicate if it is running or not.
