Ok, here is the equipment.
1. in ground spillway spa
2. len gordon controller FF-1094LTC
3. Raypak Gas heater

This thing seem's to have a mind of it own. It will come on at random times of the day. I am having problems with water in the air lines (I am having to blow them out about every month) and was wondering if the water could be causing the spa to come on. My second guess is maybe a short in the controller but when the water is cleared the controller works fine. Is the water in the air lines a coming thing with in ground spa's? I am new to the spa world so any info/ ideas would be great.

thanks in advance.
