   I have a Catalina spa with the Cat100 control . Last fall I replaced the heater just prior to the first snowfall , I could not get the tub to heat up past 52 degrees. It seemed like it was in sleep mode I tried contacting the reliable tech in our area. He said to press the light and the temp button at the same time and everything should be ok we;; same thing . So I decided to to put the tub to sleep for the winter. Just getting around to opening the tub now i powered it up I have the same problem . Any ides on how to get this thing working properly. Note: When I press the blower motor the heat light will come on for the duration og the cycle but will not continue to heat the temp is around 68

   Thanks

   I need to clarify that it is the spa blower button you are pressing and not the jet or pump button. Does the spa pump come on when you push the blower button as well as the blower? I am trying to determine if the spa topside panel causing the problem, or if you have a bad temperature sensor.

   Presently the Low speed motor is recirculating the water all of the time.The water temp now is 85 degrees and has been for the last three days. When I press the jets pump button the the heater light comes on. The blower works fine. When I turn off the jet pump the heater light goes off. The spa recirculating motor stays on ,never shuts off.

   I have also tried putting the mode into economy and back by pressing the Light button and Temperature button together nothing changes from the above paragraph
   Thanks

   Is the pump that is running constantly a circulation pump seperate from the main jet pump? If so, it should be running all the time. My thinking is, when you are turning on the main jet pump it is pushing enough water through the system closing the flow switch allowing the heater to turn on. But when it is just the circulation pump running it is not pushing enough water through to close the flow switch which would not allow the spa heater to come on. You can try removing your spa filter and run only the circulation pump and see if the heat light will come on.
