Our house in the Dallas area has three powered exhaust fans in the attic: each fan is controlled by a nearby thermostat. There are plenty of soffit vents to feed air to the exhaust fans. The rotary resistor thermostats are impossible to synch so one fan may activate before another. It occured to me that when only one or two fans are active, they might be pulling air from the inactive fan opening versus from the soffit vents. (Eventually the summer heat is enough to activate all three fans.) Should I rewire the three attic fans to be jointly controlled from one centrally located attic thermostat, or am I making work for myself? Thanks in advance.
