Hi, Im new to the site and hope someone can suggest a fix to my problem.
If I have the system set to pool (filtration and heat) and turn on my spa blower (overflow spa built into my gunite pool) it works perfectly (lots of bubbles from all jets). When I switch to spa, it all stops. The heater is working and the valves switch automatically as required, the blower is on but I get only intermittent low volume of bubbles from just 2 jets.
Where should I start?
