jandy heater

Good Evening!! I am at my whits end right now and I don't know where to turn. We got a new Jandy heater installed 2 months ago after our original heater took a Crud. Anyway we have only had our pool for 2 years so you can only imagine my frustration. Here is the issue... when the heater turns...

We just got our pool finished and I am having an odd problem with the heater and the automation system. The heater was working fine for the pool and the spa as it is combo system one heater for both. all works fine for a while and then. Was heating pool and working fine then switched to spa...
