Aquahot bay thermostat replacement or ?
We have temperature sensors in the wet bay, manifold bay, outside and inside.
I noticed yesterday that the manifold bay was hot - 85 Deg. F. The wet bay was 50F. Outside temp was 38F. I promptly went to the thermostat - rotating dial and turned it down from 50 deg to 40. Now the manifold bay reads 59 deg and the wet bay reads 50 deg. Outside temp is 48F.
Thoughts?
