I've checked the max temp and it's set at 85 for the pool and 104 for the spa.
I turn on the heater, press pool. Heater comes on, everything looks and sounds normal. After a few minutes or sometimes 10 + minutes the heater will witch over to the spa and the "heating" turns off. I can't seem to get the heater to continuisly heat the pool. I've looked over the troubleshooting guide in the owner's manual but didn't see anything that relates to my problem.
Any advice would be greatly appreciated. Kids would really like to go swimming.
