I have an Apollo system in a small guest house, and don't have an
owners manual. I just discovered that In A/C mode, hot water still
circulates through the air handler, making it impossible to cool the
house. I shut off the hot water to the air handler and the air
conditioning works now. But, I was wondering, is there a pump in the
hot water line that might burn itself out? If so, how do I shut off
power to the pump?
